Universal solutions always attract a lot of attention. This is especially noticeable when, against the background of the gray monotonous mass of radio stations, a device appears that is not similar to the others. This was the case when AnyTone AT-5555 appeared. The model turned out to be super successful and different manufacturers made a lot of clones based on it, and some went even further and this is how the Alinco DR-135CB was born.
To be precise, this is far from the first device that functionally copies the AT-5555. Long before the appearance of the Alinco DR-135CB, the creation of the French company CRE8900 was born. The station completely copied the AnyTone AT-5555, but had smaller dimensions, was slightly smaller than 1 DIN, which made it possible to install it in a standard socket from the radio, and was quite expensive. After some time, the Alinco DR-135CB appeared, which, in fact, is a complete clone of the CRE8900, only cheaper.
It must be said that this station has nothing to do with the Alinco company, just as various cheap LPD/PMR portables have nothing to do with the Kenwood brand. The device is produced at the AnyTone factory, and a beautiful and well-known name simply helps to promote and sell, in general, it’s not a bad radio station. Except in Russia, this radio station is not sold anywhere, as you can verify by going to the company’s official website. I don’t know whether the manufacturer has reached an agreement with Alinco or not, but that’s how it is. In addition, the Chinese copied the design of such stations from various American models, as you can see by just looking at.
Appearance
The station is supplied in a cardboard box. Monochrome printing.
The packaging design is made like that of a real Japanese Alinka. For those who have never seen how real Alinco is packaged, here is a photo.
The white box is from the native Japanese Alinco, which, by the way, also operates on the CB range, but only in frequency modulation and is aimed at professional use.
The equipment is completely standard. Radio station, instructions, headset, mounting kit and mounting bracket.
They can be called close to 1DIN.
Still, the station is somewhat smaller than the standard size. One good thing is that such a station is guaranteed to fit into 1 DIN socket, but you will have to think about how to secure it there.
The station itself is made in the form of a monoblock, in a classic form factor.
All controls are concentrated on the front panel. They are somewhat crowded, which can make it somewhat difficult to manage the station.
The station has 7 adjustment knobs, three of which have a dual design, so in reality there are as many as 10 adjustment knobs.
The station has 8 function buttons, plus one button on the Clarifier handle. More details about the functions will be below.
The headset is very light and constantly tries to escape from your hand, since its wire is quite rigid. Unlike the AT-5555, the central button is not marked, although it performs its functions of turning on the automatic noise suppressor if you perform some manipulations to activate this mode.
The headset connector is standard 6 pin.
There are 2 indicator displays on the front panel. The first displays frequency, modulation, and other states and operating modes of the radio station. It has 7 backlight colors, plus a mode in which the backlight color changes sequentially in a cycle, like a garland on a Christmas tree (hello AnyTone AT-608M).
The station has an interesting front panel backlight. The Americans call it NightVision. Inside the panel there are fluorescent light bulbs that illuminate the inscriptions of the handles and buttons from the inside. And despite the fact that the buttons and handles themselves do not glow in the dark, they are quite easy to find, which is convenient.
The station body is painted with black powder paint. Both housing covers are screwed to the chassis separately.
At the rear there is a massive radiator. The station produces about 12 watts per transmission in AM and FM, and about 25 watts in SSB (if you shout loudly into the microphone). The power connector is classic American, which also clearly hints at the country in which the station was designed.
Connectors for connecting an antenna, telegraph key and external speaker. The programming connector located on the rear wall deserves special attention.
It is made in the mini-USB form factor, but this is only a connector. The pinout does not correspond to classic USB and you should not stupidly use a regular USB cable, since this can damage both the station itself and the USB connector in the computer system unit.
Functions
The station has very rich functionality for a regular CB transceiver and 10 meter band.
- Knob for switching range or grids (depending on mode)
- Knob for switching the type of modulation. PA – voice is broadcast to the speaker of the radio station, CW – when a telegraph key is connected to the socket on the back of the radio station, it allows telegraph operation, AM – amplitude modulation, FM – frequency modulation, USB – upper sideband, LSB – lower sideband.
- Knob to turn the radio on/off and adjust the volume.
- Threshold squelch adjustment knob.
- Knob for turning on/off the Echo mode and adjusting the volume of the effect.
- Echo duration adjustment knob.
- Receiver sensitivity adjustment knob.
- Power output adjustment knob.
- Frequency fine adjustment knob and button capable of performing some other functions. By default, changes the frequency step of the knob setting.
- Channel switching knob.
- FUNC button – in combination with other buttons, allows you to call up second, additional functions of the latter. To call an additional function, you need to briefly press the FUNC button and briefly press the desired function button. A long press on the FUNC button allows you to enter the Menu, more about it below.
- RB, BP button – a short press on the button allows you to turn RogerBeep on/off. In combination with the FUNC key, turns the key beeper on/off.
- NB/ANL, LOCK button – a short press turns on/off two filters Noise Blanker, which suppresses interference from the ignition system and Automatic Noise Limiter, a filter that limits airborne noise. In combination with the FUNC key, it allows you to lock the station control.
- DW button, LCD OFF – a short press activates the two-channel listening mode. To configure this mode, you need to select the first channel, press the DW button, switch to the second channel, and confirm the selection with the DW button. The second function called through the combination with the FUNC button is to turn off the main display. The display with the channel number remains lit.
- SCAN, SC LIST button – a short press activates the scanning mode. Scanning occurs within the same grid. The scanning direction can be changed using the channel switch knob. The second function called through a combination with the FUNC button is the formation of the so-called. scan of the sheet. You can exclude certain channels from the scanning list, leaving only those that are of interest. In this case, the excluded channel is marked with a dot on the frequency display, near the number 2. (2.7,2.8...).
- Button +10kHz, Hi-Cut – a short press allows you to quickly switch up 10kHz, which is sometimes necessary for quick tuning into a “hole”. The second function, called through the combination with the FUNC key, is to turn on the low-pass filter for reception, which allows you to listen to the broadcast more comfortably.
- COL, TOT button – a short press changes the color of the display backlight, and through a combination with the FUNC key, you can turn on/off the transmission timeout.
- EMG, S/RF button – a short press allows you to switch the station to emergency channel 19, and in combination with the FUNC button turns the multifunctional S-meter scale on and off.
Menu
The station has a menu. It consists of a bunch of items and allows you to program some functions of the station. The abbreviations denoting the functions are not at all obvious, and from what is displayed on the display it is quite difficult to guess what this or that item is needed for.
Enter the menu by pressing and holding the FUNC button. Navigation through the menu is carried out by the FUNC button, and switching of parameters is carried out by the channel switching knob.
iC9– Adjusts microphone gain
nO9– The so-called Talk Back or how loudly in transmit mode you will hear yourself from the speaker of the radio station.
CSu– CW tone volume adjustment

rbF– Roger Beep frequency setting. 300Hz – 3kHz.
rbt– Setting the Roger Beep playing time.
CFr– Setting the telegraph tone frequency.
ton– Setting the frequency of a single tone.
Engineering menu
I have already described the method for entering the engineering menu for . Everything is similar here. If you don’t know why you need the engineering menu, then I highly recommend not getting into it!
Switching ranges
This is done by rebooting the station. Usually, out of the box, the station comes with the 10m band turned on, to switch to CB you need to do the following. Turn off the station. Press the FUNC + EMG buttons and turn on the station.
1bAnd appears on the display. Use the channel switching knob to switch the station to 2bAnd mode, then press and hold the FUNC button for about 3 seconds until the words “rese” and “End” appear. Turn off the radio station and turn it on. The station wakes up in the required range.
Turn on automatic squelch
Out of the box, the central button on the headset (the AT-5555 has an auto-squelch on it) does not respond to presses, although it may well perform its functions. To turn on the button, you need to turn off the radio station, hold down the FUNC + DW buttons and turn on the station.
ASQ appears on the display. Rotate the channel switching knob to set En. Turn off the radio and turn it on. Now the button on the headset will turn automatic noise reduction on and off.
Inside
The installation is made on a board made of green PCB. Overall, it's quite neat. This type of editing is found in all AnyTone. I can’t call it thoroughly polished, like, for example, presidents, but overall everything is more or less decent and quite up to par.
The processor is located on the main board. It is the same as the AT-5555.
Output stage voltage regulator, also known as AM modulator.
Stabilizer and ULF
Under the screens are the receiver input circuits
The front panel backlight board is located here.
The output stage is built on 3 IRF520 transistors and one 2SC2314. Out of the box it puts out about 12 watts on AM and FM, and about 25 watts on SSB.
Voltmeter and SWR meter
The built-in SWR meter and voltmeter cannot be called accurate. These are rather indicators that give an approximate picture of what is happening with power and AFU. In my copy, the voltmeter slightly underestimated the readings, by an average of 0.1V, while the standard SWR meter underestimated them greatly and spread them across the range. I was not lazy and took the characteristics of the built-in SWR meter and this is what happened.
Here's a picture of how my base antenna is configured. For comparison, the readings of the FG-01 antenna analyzer are presented. It’s not a very rosy picture, but it’s quite suitable for indicating that something is wrong with the antenna. Most likely, deviations in readings will vary from instance to instance, so this is not an absolute picture.
Modifications
Bottom line
The station was a success. It is quite capable of working out of the box. It has excellent sensitivity and everything necessary for working on the air, not only on CB, but also on the 10-meter amateur band. True, it is not very convenient to change frequencies there, but, nevertheless, such an opportunity exists. Modulation and threshold noise reduction, after simple modifications, will delight you with their sound and, accordingly, behavior on the air. On the Internet there are user reviews about a certain percentage of defects in produced radio stations, but it is very insignificant. The station can be recommended to a wide range of civil band enthusiasts for the implementation of any communication-related tasks. I don’t see any point in installing it in a car, since due to the overload of functions, it will be difficult to control the transceiver while driving. But as a basic device, this option deserves close attention.

INSTALLATION
1. WHERE AND HOW TO INSTALL THE RADIO STATION
a) You must choose the most suitable installation, a simple and practical point of view.
b) Your radio must not interfere with the driver or passengers.
c) Remember to protect wires (eg power supply, antenna, accessory cables) so that they do not in any way interfere with the driving of the vehicles.
d) To install the equipment, use the bracket and screws provided (5mm diameter). Be careful not to damage the vehicle's electrical systems when screwing into the dashboard.
e) Be sure to insert the rubber joints between the radio and the bracket as They have a shock-absorbing effect that gives smooth rotation and a strong fit.
f) Choose where to place the microphone mount and remember that the microphone wire should extend towards the driver without interfering with vehicle control.
To use the walkie-talkie, first, connect the antenna to location "B" on the back of the equipment, and then set the SWR (Standing Wave Ratio) before transmitting. Failure to do so may result in malfunction of the power amplifier and void the warranty.
2. ANTENNA INSTALLATION
a) Antenna selection:
For radio stations, the larger the antenna, the better the results. Your dealer will help you select an antenna.
b) Mobile antennas:
Must be installed on a vehicle where there is a maximum of metal surface (plane) away from the windshield.
There are two types of antennas: Pro-variable antennas, which should be used on a well-grounded surface (such as a car roof or trunk lid) and a variable antenna, with a wide frequency range and used on a small surface. For roof or fender mount antennas, good contact between the antenna and the ground surface is required. To achieve this, you will need to lightly sand the cut hole where the screw and castle washer will be placed.
Be careful not to pinch or pinch the coaxial cable (as you risk breaking and/or shorting).
Connect the antenna to location (B).
c) Fixed antenna:
The fixed antenna should be installed in as much free space as possible. If it is attached to a mast, it is necessary to check the current legislation (you should seek professional advice). All DR-135CB antennas and accessories are designed to provide maximum performance for each station within the range.
3. POWER CONNECTION
The Alinko DR-135 27 MHz New radio station has reverse polarity protection. However, before turning it on, it is recommended to check all connections. Your equipment must supply 12 volts DC. Today, most cars and trucks have a negative ground. You can check this by making sure the negative terminal of the battery is connected to the engine block or chassis. If that's not the case. You should contact your dealer.
WARNING: Trucks typically have two 24 volt batteries, in which case it will be necessary to install a 24/12 volt converter in the electrical circuit. The following connection steps must be carried out with the power cable disconnected from the mains.
a) Check if the battery is 12 volt.
b) Locate the positive and negative terminals of the battery (+ red, - black). If the power cable needs to be extended, please use the same or better type of cable.
c) This is necessary to connect the radio permanently (+) and (-). We advise you to connect the power cable directly to the battery (connecting the cable to the car radio wiring or other parts of the electrical circuit, as in some cases it may cause interference).
d) Connect the red wire (+) to the positive terminal of the battery and the black wire (-) to the negative terminal.
e) Connect the power cable to the station.
WARNING: Never replace the factory fuse (10 A) with a different rating.
4. BASIC OPERATIONS MUST BE PERFORMED BEFORE USING THE TRANSMISSION JOB FOR THE FIRST TIME
(without transmission or using “Push-To-Talk” to turn on the microphone)
a) Connect the microphone
b) Check that the antenna is connected correctly
c) Turn on the device by turning the volume knob clockwise
d) Turn the squelch knob to minimum
e) Adjust the volume to a comfortable level
f) Go to channel 20@D grid using the UP or DN buttons on the microphone or rotating the channel selector knob.
5. SETTING SWR (Standing Wave Ratio)
WARNING: This must be done the first time you use the radio (and every time you move the antenna). Adjustments must be made in an area free of obstructions.
Tuning using built-in or external SWR meter
a) To connect an SWR meter.
Connect the SWR meter between the radio and the antenna, as close to the station as possible (use a cable no longer than 40 cm).
b) To adjust the SWR meter.
Install the Alinco DR-135CB NEW device on channel 20@D of the FM grid.
Set the SWR meter switch to CAL or FWD.
Press the Push-To-Talk switch on the microphone to transmit.
Move the arrow to the T pointer using the calibration button.
Set the switch to the SWR position (reading the SWR level). The measurement reading should be as close to 1 as possible. If it is not, realign your antenna to get a reading as close to 1 as possible. (SWR values between 1 and 1.8 are acceptable).
It is necessary to recalibrate the SWR meter after each antenna adjustment.
6. HOW TO USE SWR METER (KCB METER)
Set the DR-135CB NEW radio to channel 20@D of the FM grid.
Press the Push-To-Talk button on the microphone to transmit.

Basic Operations Setting CTCSS / DCS Many repeaters require a CTCSS tone or DCS code as a “key” to enter the system, the so-called “selective call”. Sometimes CTCSS or DCS is used at the repeater output to open the squelch of a particular radio station. In this mode, the radio subscriber will hear the caller through the other subscriber's repeater ONLY when the corresponding tone/code is received. The combination of CTCSS noise reduction and DCS codes function is not available; For a given memory channel, only one or the other can be used. 1. Press the TS/DCS key. These settings will be indicated by the T/SQ/DCS icons on the display and the CTCSS tone frequency or DCS code number. Press the same key to select T/SQ/DCS as shown in the figure. 2. Numbers like 88.5 represent the CTCSS frequency in Hz. When it is displayed with only a T icon, the radio transmits a CTCSS tone while the PTT button is pressed (encoding) and the repeater provides access to the radio channel of the radio station that sends the 88.5 Hz tone. 3. Press the same key again so that the SQ icon appears on the display. Then the CTCSS decoder mode will turn on at this frequency. This will enable the TSQ tone squelch mode. 4. Press the same key again until the display shows the 3-digit number and the DCS icon. This is a DCS code, the DCS code encoder/decoder is enabled. To select CTCSS or DCS frequencies, rotate the channel selector or press the UP/DOWN keys to change the tone or code. Press any key other than the TSDCS/UP/DOW N key to enter the setting and return to the original state. The T/SQ/DCS icon on the display indicates the current status. To turn off the CTCSS/DCS coding mode, you simply press the TSDCS key and the T/TQ/DCS icon will disappear. The CTCSS encoder/decoder frequencies can be set to different values. When setting the frequency to oder, the decoder frequency will automatically be set to the same, but it can be changed. A standard set of 39 different CTCSS tones are available, as shown in the diagram below. The DCS codes for the encoder/decoder cannot be different, they are selected from a list of 104 codes as shown below. CTCSS Frequency (Hz) DCS Codes PLEASE NOTE: Depending on the level of deviation, the incoming DCS scrambled signal may not open your station's DCS squelch.

For the mobile station set:
Location
The transceiver can be installed anywhere in your vehicle where the control panel and microphone are easily accessible and do not interfere with safe driving. If your vehicle is equipped with airbags, make sure your radio will not interfere with their deployment. If you are unsure about where to install the transceiver, contact your vehicle manufacturer.
Mobile antenna installation
Use 50 ohm coaxial cable to connect the antenna. Mobile antennas require an appropriate base for reliable installation and operation. For more information, see your antenna documentation.
Caution: After installing your antenna, be sure to tune the antenna to obtain the lowest SWR (standing wave ratio) value. High levels of external radio frequency radiation can cause serious damage to your radio. Make sure you are not in an area of high radio frequency radiation when the transceiver is operating.
Transceiver installation
See picture below 
Before installation, make sure that your vehicle's 12VDC electrical system has a negative battery terminal on the body. Connect the DC cable directly to the battery as shown below to minimize possible interference. Make sure the vehicle has a large capacity battery as using a transceiver may overload the vehicle's electrical system.
To turn the device on/off using the ignition key, you can use additional accessories EDC-37 (cable for direct connection to the ignition switch circuit) or EDC-43 (cable for connection to the cigarette lighter EDC-36 is also compatible).
Connect one of the cables between the ignition switch or cigarette lighter, which operates only when the vehicle's ignition is turned on, and the EXT POWER jack on the rear of the transceiver.
NOTE: Many cars always have voltage at the cigarette lighter. If this is the case on your car, then you cannot use the cigarette lighter to turn the transceiver on/off.
If this option is selected, the transceiver can be turned on/off manually or automatically according to the position of the ignition key:
1. When the ignition key is in the lock or in the ON (Start) position and the transceiver is turned off, the PWR button lights up. This button will go out if the ignition key is in the OFF position. To turn on the radio, you need to press the PWR button while the button backlight is on (when the ignition key is in the lock, or in the ON position).
2. When the ignition key is in the lock or in the ON position with the transceiver turned on, the radio will turn on automatically and the PWR button will always be illuminated. Remove the key from the lock or press the PWR button to turn off the transceiver/
Current consumption when using an additional cable is 5mA. To operate without this option, use the switch on the transceiver.
Power supply voltage display function
After connecting the transceiver to the power supply, the power supply voltage can be measured. When the SQL key is pressed in place of the FUNC key, the supply voltage value on the transceiver will be displayed on the display. The transceiver will return to normal mode after turning off the power.
The display responds immediately to voltage changes.
The voltage during transmission is also displayed.
IMPORTANT: The displayed voltage range is only from 7V to 16VDC. Therefore, for more accurate measurements, please use a voltmeter.

Setting the levelThe noise suppressor eliminates “white noise” (background noise in the absence of a useful signal). If the squelch level is too high, then weak signals will not be received, but the quality of strong signals received will be very good due to the low noise level. With a low squelch level, weak signals from correspondents will be heard, but at a high noise level. 1. Press the SQL key. The SQL icon will appear on the display and the SQL level will be shown in the position for the memory channel number. There are 21 levels available, between 0 and 20. “0” is the lowest setting. 2. Rotate the channel selector, or use the UP/DOWN keys on the microphone, to set the desired level. To return to normal mode, press PTT, or any of the keys on the front panel; If you do not press anything, the transceiver will still store this setting for 5 seconds, then return to its original status. The new squelch level will be saved until another setting is entered. |

Working with a repeaterShift direction and setting the shift frequency |
||
|
Conventional repeaters operate in DUPLEX mode. This means that the repeater receives a signal on one frequency (UP - LINK) and transmits on another (DOWN - LINK). The difference between these two frequencies is called the offset frequency. If the frequency UP - LINK is higher than the frequency DOWN - LINK direction is positive, if lower, the shift direction is negative. The offset can be set between 0 and 99.995MHz on this radio. |
 (-600kHz) |

Installation /
Many repeaters require a CTCSS tone or DCS code as a “key” to log into the system, called “selective calling”. Sometimes CTCSS or DCS is used on the repeater output to open the squelch of a particular radio. In this mode, the radio subscriber will hear the caller through the other subscriber's repeater ONLY when the corresponding tone/code is received. The combination of CTCSS noise reduction and DCS codes function is not available; For a given memory channel, only one or the other can be used.
1. Press the TS/DCS key. These settings will be indicated by the T/SQ/DCS icons on the display and the CTCSS tone frequency or DCS code number. Press the same key to select T/SQ/DCS as shown in the picture.
2. Numbers like 88.5 represent the CTCSS frequency in Hz. When it is displayed with only a T icon, the radio transmits a CTCSS tone while the PTT button is pressed (encoding) and the repeater gives access to the radio channel of the radio station that sends the 88.5 Hz tone.
3. Press the same key again so that the SQ icon appears on the display. Then the CTCSS decoder mode will turn on at this frequency. This will enable the TSQ tone squelch mode. 4. Press the same key again until the display shows a 3-digit number and the DCS icon. This is a DCS code, the DCS code encoder/decoder is enabled.
To select CTCSS or DCS frequencies, rotate the channel selector or press the UP/DOWN keys to change the tone or code. Press any key other than the TSDCS/UP/DOWN key to enter the setting and return to the original state. The T/SQ/DCS icon on the display indicates the current status. To turn off the CTCSS/DCS coding mode, you simply press the TSDCS key and the T/TQ/DCS icon will disappear.
The CTCSS encoder/decoder frequencies can be set to different values. When you set the encoder frequency, the decoder frequency will automatically be set to the same, but it can be changed. A standard set of 39 different CTCSS tones are available, as shown in the diagram below. The DCS codes for the encoder/decoder cannot be different, they are selected from a list of 104 codes as shown below.
 CTCSS frequency (Hz) |
 DCS Codes |
PLEASE NOTE: Depending on the level of deviation, the incoming DCS encoded signal may not open your station's DCS squelch. If this occurs, return to the DCS mode setting and press the CALL key. The display will show a decimal point in the 10MHz digit; after that install the required code. This setting can also be stored in a memory channel.
Memory mode
The memory mode in this transceiver provides 100 channels (0-99), 1 operational channel and two channels for priority scanning, easy access to programmable channel frequencies with various settings.

[Programming data in memory channels]
Some features will be explained later, please read these instructions completely.
Memory channels, including 0 - 99 and the operational channel can store the following data:
Frequency
offset frequency
shear direction
CTCSS tone encoder and decoder
Tone squelch mode T/TSQ
DCS encoder/decoder codes
DCS squelch mode
sign of missed channel during scanning
sign of transmission blocking on a busy channel
priority frequency control (programmable via PC)
normal/narrowband FM receiver
reception in the aviation range of AM signals (only for DR-135T).
PLEASE NOTE: Only frequency can be stored in the PH and PL channels to define band boundaries.
Operational channel mode
This is a memory mode that allows the DR-135 to quickly select an assigned memory channel by pressing the CALL key, regardless of the current radio status. The default frequency of the operational channel is 145.00MHz.
|
1. Press the CALL key. The C icon will appear on the display and the transceiver will enter CALL mode. In this mode, the channel switch or UP/DOWN keys cannot change memory channel numbers or frequency. |
 |
|
2. Press the CALL key again or press the V/M key to exit CALL mode. 3. In CALL mode, no viewing functions are available. 4. To store the desired data in the operational channel, use memory programming commands. Write the selected parameters to channel C. The parameters of the operational channel can be changed, but channel C itself cannot be deleted or hidden. |
Receiving signals
Make sure the antenna is connected to the radio, the transceiver is turned on, and the volume and squelch levels are set to the appropriate levels.
Select the receiving frequency you need, or frequencies to browse the channels you need to listen to. The S-meter shows the signal level between the BUSY and FULL marks when the transceiver detects an incoming signal.
If the S-meter indicates a signal but there is no sound from the speaker, check the volume level, squelch level, and CTCSS/DCS decoding settings, which are explained elsewhere in this manual.
The Monitor function is designed to receive weaker signals. Press and hold the SQL button for more than 1 second. Regardless of the signal level, the squelch will open, the BUSY icon will appear on the display, and you will hear a signal through the speaker. Press any key on the front panel to enter noise canceling mode.
....Broadcast
|
1. Select the desired frequency. You must be sure that you are authorized to operate on this frequency. Check that there is no signal so as not to interfere with correspondents broadcasting on that frequency at that time. 2. Select transmit power. Press the FUNC key, then press the CALL key while the F icon is shown on the display. By pressing the CALL key you can select one of three power levels. The Lo icon means low power, Mi means medium power. When the transceiver is set to High Power mode, these icons will not appear on the display. The transmit power level cannot be changed while the PTT key is pressed. |
|
|
3. The default is high power. Press the PTT key on the microphone to transmit and release to receive messages. During transmission, the power level is shown on the radio display in the form of segments. LOW POWER = 2 segments, |
 low power  average power  high power |
|
4. When powering the transceiver from a car battery, avoid long transmission times with the engine off, as this will lead to intense battery drain. Check battery voltage frequently. Also, current consumption increases significantly when the headlights, stereo, air conditioning and other auxiliary systems of the car are turned on. If all these systems are turned on, the output power of the transmitter is reduced, so some of them are turned off to reduce the load on the car's battery. Monitor the traffic situation when working on the road. Check local regulations regarding the use of radio frequencies and mobile radio transmitters in the area. |
Parameter setting mode
Important: Please read the following pages in full before changing any settings.
THE PARAMETERS CANNOT BE CHANGED WITHOUT ACTIVATING THE INSTALLATION MODE.

Details and features of the parameter setting mode menuThe specific procedure for setting some parameters is explained in more detail later. |
Setting the channel stepThe channel step is selected in VFO mode. Refer to the chart below to determine your actual cadence. |
 |
TypeThe scanning type allows you to select one of the conditions - scanning by timer (TIMER) or by time of presence of the signal carrier (BUSY). Timer scanning allows the radio to resume scanning 5 seconds after finding a busy channel, regardless of whether it remains busy after the 5 seconds have elapsed. When scanning the BUSY type, the radio resumes scanning only when transmission has ended on a given channel and the signal is not indicated. Scanning modes are explained later. |
 |
Sound signalThe beep is turned on when BEEP-ON is set. This means that a beep will sound when you press some keys. When set to BEEP-OFF, the beep sound is disabled. |
 |
TOT transmission time limitation
TOT is especially popular in repeater systems. This mode prevents the user from transmitting after a certain period of time has elapsed. By setting this function as required by repeater systems, the radio alerts the user with an audible signal 5 seconds before the end of this time. When the time expires, the transceiver automatically stops transmitting and enters receive mode. This allows the repeater to switch to TOT mode for the next correspondent. Until the PTT button is released and pressed again, the transceiver will not transmit.
Pause timer between TOT Penalty transmission sessions
When the TOT mode is set, this function prohibits transmission if less than the time set in this mode has passed from the moment of one PTT press to the next.
.....Auto shutdown mode APO - OFF
In this mode, the transceiver automatically turns off. This is useful for the mobile station to avoid draining the car battery. If there is no radio traffic, a beep will sound after 30 minutes and the transceiver will automatically turn off.
Ring tone frequency
This mode allows you to activate the operation of some repeaters or correspondents that are in standby mode by emitting an audible tone of a certain frequency. Typically, a repeater system does not require a tone if the repeater is activated.
Blocking transmission on a busy BLCO channel
This function disables transmission if there is a signal on the transmit frequency. The default value is BCLO-OF. By activating this function, the radio transmits only when:
Alphanumeric label
Channels stored in memory mode may be shown on the display with an alphanumeric mark instead of a frequency. First program the channels into memory. A total of 67 characters are available, including the letters A-Z and numbers 0-9.
|
1. Enter installation mode when the radio is in memory mode. |

List of TNC commands
All commands are supported by the built-in TNC. You must enter a space between the command name and the parameter, or between two parameters.
| Team | Short form | Default | Options | Description |
|---|---|---|---|---|
| AUTOLF | AU | ON | ON/OF | When ON, sends a line feed (LF) to the PC after each carriage return (CR). |
| BEACON | B | EVERY 0 | EVERY/ AFTER n (n=0 – 250) |
If set to EVERY, sends a beacon packet at intervals of the specified period (n). If set to AFTER, sends a beacon packet only once after the specified period (n). The unit of n is 10 seconds. |
| BTEXT | BT | - | 0 –159 characters | Specifies the content of the data portion of a beacon packet. |
| CALIBRAT | CAL | - | - | Sends a space/mark square wave (50/50 ratio). Enter Q to exit Calibrate mode and restore the Command mode. |
| CHCAK | CH | 30 | 0 – 250 | Specifies the interval from signal drop-out until execution of disconnection. The unit of the parameter is 10 seconds. |
| CONNECT | C | - | Call1 (VIA call1, call3, ....call9) |
Sends a connect request. Call 1 is the call sign of the station to be connected to. Calls 2 to call 9 are call signs of stations to be digipeated through. |
| CONVERSE | CONV or | - | - | Causes the TNC to enter Converse mode. Press +[C] to restore the Command mode. |
| CPACTIME | C.P. | OFF | ON/OFF | When ON and in Converse mode, sends a packet at intervals of the period determine by PACTIME |
| CR | CR | ON | ON/OFF | When ON, appends a carriage return (CR) to all packets to be sent. |
| DISCONNE | D | - | - | Sends a disconnect request. |
| DISPLAY | DISP | - | - | Causes the TNC to display the current status of all the commands. You can also specify a class identifier A, C, H, I, L, M, or T to display the status of only the desired command class. Enter a space between the command name and a class identifier; ex. DISPLAY H. A (ASYNC): RS-232C port parameters. C (CHAR) : Special TNC characters H (HEALTH): Counter parameters. I (ID): ID parameters. L (LINK): TNC-to -TNC link status. M (MONITOR): Monitor parameters. T (TIMING): Timing parameters. |
| DWAIT | DW | 30 | 30 | Specifies the interval from no carrier detection until execution of transmission. The unit of the parameter is 10 milliseconds. |
| ECHO | E | ON | ON/OFF | When ON, causes the TNC to echo received characters to the computer. |
| FIRMRNR | FIR | OFF | ON/OFF | The other station sends a notice (packet) to you if it is not ready to receive data. When ON, receiving such a notice causes the TNC to suspend transmission until it receives a “ready” notice. |
| FLOW | F | ON | ON/OFF | When ON, starting key entry causes the computer to stop displaying received packets. |
| FRACK | FR | 3 | 0 – 250 | Specifies the interval from one transmission until retry of transmission. The unit of the parameter is 1 second. |
| GBAUD | G.B. | 4800 | 4800/9600 | Selects 4800 or 9600 bps as the transfer rate between the TNC and the GPS receiver. |
| GPSSEND | GPSS | - | 0 – 59 | Specifies the content of the data to be output characters to the GPS receiver; this data is used to program the default settings on the receiver. The output data is not stored in memory. |
| GPSTEXT | GPST | $PNTS | 0 – 6 characters | Specifies the type of a message to be determined by LTEXT. |
| HBAUD | HB | 1200 | 1200/9600 | Selects 1200 or 9600 bps as the transfer rate between packet stations. |
| LOCATION | LOC | EVERY 0 | EVERY/ AFTER n (n = 0 - 250) |
If set to EVERY, sends GPS data at intervals of the specified period (n). If set to AFTER, sends GPS data only once after the specified period (n). The unit of n is 10 seconds. |
| LPATH | LPA | GPS | Call1 (VIA call2, call3, ... call9) |
Specifies calls signs to send GPS data. Call 1 is the call sign of the destination. Call2 to call9 are call signs of stations to be digipeated through. |
| LTEXT | LT | - | 0 – 159 characters | Specifies the content of a message to be included in GPS data. |
| LTMON | LTM | 0 | 0 - 250 | Specifies the interval for displaying a message determined by LTEXT on the screen; a message appears like a received beacon packet. The unit of the parameter is 1 second. |
| MCOM | MCOM | OFF | ON/OFF | When ON, causes the TNC to also monitor control packets. When OFF, causes it to monitor only information packets. |
| MCON | M.C. | OFF | ON/OFF | When ON, causes the TNC to monitor other stations while in connection with the target station. |
| MONITOR | M | ON | ON/OFF | When ON, causes the TNC to monitor packets. |
| MRPT | M.R. | ON | ON/OFF | When ON, causes the TNC to display the entire digipeat list for monitored packets. |
| MYCALL | M.Y. | NOCALL | 6 characters + SSID | Specifies your call sign. |
| PACLEN | P | 128 | 0 – 255 | Specifies the maximum length of the data portion of a packet. |
| PACTIME | PACT | AFTER 10 | EVERY/ AFTER n (n=0~250) |
If set to EVERY, sends a packet at intervals of the specified period (n). If set to AFTER, sends a packet only once after the specified period of (n). The unit of n is 100 milliseconds. |
| PERSIST | P.E. | 128 | 128 | Specifies a parameter to calculate probability for the PERSIST/SLOTTIME method. |
| PPERSIST | PP | ON | ON | Causes the TNC to use the PERSIST/SLOTTIME method when ON, or the DWAIT method when OFF. |
| RESET | RESET | - | - | Restores the default status for all the commands. |
| RESPTIME | RES | 5 | 5 | Specifies the acknowledgement packet transmission delay. The unit of the parameter is 100 milliseconds. |
| RESTART | RESTART | - | - | Causes the TNC function as if it is switch OFF then ON. |
| RETRY | RE | 10 | 10 | Specifies the number of transmission retries. If packets are not correctly accepted while in connection, a connect request is sent again after the specified number of retries. |
| SENDPAC | S.E. | $0D | $0D | Specifies a character that forces a packet to be sent. |
| SLOTTIME | SL | 3 | 3 | Specifies the period of random number generation intervals for the PERSIST/SLOTTIME method. The unit of the parameter is 10 milliseconds. |
| TRACE | TRAC | OFF | OFF | When ON, causes the TNC to display all received packets in their entirety. |
| TRIES | TRI | 0 | 0 | Specifies the number of transmission retries programmed in the retry counter. |
| TXDELAY | TX | 50 | 50 | Specifies the time delay between PTT ON and start of transmission. The unit of the parameter is 10 milliseconds. |
