Sometimes I am amused by situations when people buy something based on the steepness of the equipment, and not its functional purpose. Either people are really pricked without delving into the essence of the issue. And so, from time to time they bring me Alinco DR-135T, DR-135E and other Alinkas designed to work in the two-meter range. But they ask them to tune in to the international channel of freight carriers (truckers). At the same time they poke at Internet and they say that someone sets them up. Therefore, especially for colleagues in the shop and to simplify the life of the truckers themselves, I decided to devote a short article about Alinkas, their varieties and the possibility of their use for working in the international channel of cargo carriers. I'll start the story about the fact that there is Alinco DR-135 that operate at frequencies of the two-meter range.

Alinco DR-135T/DR-135TE/DR-135F

And so, if you look closely at the inscription on the case, it indicates that the VHF range is used. This is a range of two meter waves. And a radio station "sharpened" to operate at frequencies of 136-174 MHz will not be able to operate at a frequency of 27 MHz. I already wrote about the problem of mismatched frequencies in an article about why Baofeng does not work with truckers. Therefore, if you were sold a radio station designed for the VHF band, then they simply threw you or did it because they did not pay due attention to your question that the radio station should operate on the CB band in amplitude modulation.

Alinco DR-135CB

This piece of iron is already closer to truckers. At least this Alinka can work in the CB range. But there is one problem, which is the type of modulation. The vast majority of truckers use amplitude modulation, and the Alinco DR-135 CB uses exclusively frequency modulation. Actually, the fact that this transceiver works in frequency modulation is written right in the name of the HF model FM TRANSCEIVER.

You cannot switch this transceiver from frequency modulation to amplitude modulation. Maybe a soldering iron, a couple of additional modules, and such and such a mother can be turned into an amplitude one, but why pay for the work, the cost of which will exceed the cost of the radio station and with an unknown result? Although for similar work just not a single specialist will be taken.

In some places in Russia, more precisely in the European part of Russia, some truckers switched to communication in frequency modulation. In principle, this transition was due to two factors. Firstly, the whole of Europe uses frequency modulation, and amplitude modulation is not used due to the fact that it is very outdated and not suitable for communication in urban areas. Secondly, after the transition of taxi drivers from radio stations to Internet applications, a lot of radio stations operating in frequency modulation appeared on the market. Apparently, these two factors gave impetus to the use of frequency modulation on truckers' trucks. But, in any case, you need a radio station that can switch between modulation types.

Alinco DR-135CB NEW

Interesting radio station. It is interesting if only because it has nothing to do with Alinco, except for the name on the box. Nowhere, except for Russia, this radio station under this name is not found. Apparently in Russia no one pays attention to this coexistence, or they are thus carrying out their own product substitution. In fact, inside and out, it's the AnyTone AT-5555 radio. Is that a nameplate from Alinco. On its own, the AnyTone AT-5555 is a great product for hams and civilians alike. The fact is that it is claimed to work at frequencies of 28.000-29.700 MHz, but in fact, after disclosure, it starts to work at frequencies of 25.615-30.150 MHz. And if you take into account the huge number of modulations offered by this device, then this radio station will be just a chic gift for both civilian radio amateurs and ordinary radio amateurs operating on the ten-meter wave band.

These are the radio stations that are suitable for truckers and it is about them that they write on the Internet with a lot of recommendations. In fact, for any average trucker who is not fond of radio communications, this device will be extremely redundant. Not only is it expensive, but it is also equipped with a mass of switches that will never come in handy for communication on the track. So, think a dozen times about whether you need it or whether it will be easier to turn your attention to a brand that is less promoted on the Internet. In fact, this brand is more promoted not among truckers, but among radio amateurs working in the CB band.

For truckers, I would recommend looking for models without a lot of settings. For example, such representatives as Alan, MegaJet, TTi or Vector. I hope that now it is clear why there is such a hype with the fact that someone praises Alinco, and someone claims that it is not suitable for the needs of truckers.

5. Basic operations

Turning the radio on and off Press the PWR button, or turn the ignition switch to the ON position according to the option selected at installation to turn on the radio. Press the PWR button again or turn the ignition key to the OFF position to turn off the radio.	PWR key
Setting the volume level Rotate the VOL button clockwise to increase the sound level, counterclockwise to decrease it. Set the volume to the desired level.	Minimum volume	Maximum volume
	Volume button
Level setting The squelch eliminates “white noise” (background noise when no signal is being received). If the squelch level is too high, then weak signals will not be received, but the quality of received strong signals 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 keep this setting for 5 seconds, then return to the original status. The new squelch level will be saved until another setting is entered.	Squelch level
VFO mode The VFO setting is factory default. The VFO (Variable Frequency Oscillator) allows you to change the frequency according to the selected channel pitch by rotating the channel selector or using the UP/DOWN keys on the microphone. VFO mode is also used when programming data to be stored in memory channels or for changing transceiver setup parameters. 1. Check the current mode on the display. If the “M” or “C” icon is not displayed on it, then the radio is already in VFO mode. 2. If the “M” or “C” icon is displayed on it, press the "V/M" key until these icons disappear.	VFO mode
Rotate the channel switch clockwise to increase the frequency, counterclockwise to decrease it. The UP/DOWN keys on the microphone work in the same way.	installation	increase in frequency
Frequency changes in steps of 1 This will allow you to quickly change the frequency in 1 MHz steps. 1. Press the MHz key. The numbers after 100KHz will disappear from the display. 2. Rotate the channel selector to set the desired frequency.
Changing the channel pitch 1. Make sure the radio is in VFO mode. Refer to page 21 and enter the SET mode. 2. Select the channel step frequency using the setting button.	Changing the channel pitch
3. Press PTT or any of the keys other than SQL on the front panel to enter the desired pitch into the transceiver's memory. The display will then return to the original status. Please note that settings below 10KHz may be automatically corrected according to the selected step, you must select an odd frequency. Working with a repeater Shift direction and shift frequency setting
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 UP - LINK frequency is higher than the DOWN - LINK frequency the direction is positive, if lower, the shift direction is negative. The offset can be set between 0 and 99.995MHz on this radio.	(-600kHz)
Press the F key. While the F icon remains on the display, press the MHz key. The display shows the current status of shift direction and shift frequency. The default value is 0.60 MHZ (600KHz) in the negative direction. Press the MHz key until the desired offset direction is set. If the SIMPLEX mode is needed (receiving and transmitting frequencies are the same), then you need to select the position when the - and + icons are not visible on the display.	shear direction
1. Rotate the channel selector or the UP/DOWN keys on the microphone to change the offset frequency. 2. It changes according to the set channel pitch. 3. In this mode, if the F key is pressed again, the offset frequency can be changed in 1MHz steps for fast setting. 4. Press PTT or any key other than F or MHZ on the front panel to return to the original status.

...

Installation /

Many repeaters require a CTCSS tone or DCS code as a "key" to enter the system, a so-called "selective call". Sometimes CTCSS or DCS is used at the output of the repeater to open the squelch of a specific radio. In this mode, the radio subscriber will hear the caller through the other subscriber's repeater ONLY when the corresponding tone/code signal is received. Combination of CTCSS squelch and DCS code function is not available; only one or the other can be used for a given memory channel.

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 (coding) and the repeater grants access to the radio channel of the radio station that is sending the tone at 88.5 Hz.

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 to display the 3-digit number and the DCS icon. This is a DCS code, a DCS code encoder/decoder is included.

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 encoding mode, 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 you can change it. A standard set of 39 different CTCSS tones is 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, an 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 at 10MHz ; after that install desired 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.

1. Press the V/M key. The M icon will appear on the display. This means the radio is in memory mode. Press the V/M key again to switch to VFO mode.	memory mode
2. In memory mode, rotate the channel selector, or press the UP/DOWN keys to change the memory channel number.	memory channel
3. To change the channel number after 10, press FUNC and rotate the channel selector, or press the UP/DOWN keys while the F icon is displayed. 1. Set the VFO mode by pressing the V/M key. Frequencies and channel parameters are programmed in VFO mode and will be stored later in memory.
2. When all parameters have been entered, press the FUNC key. The F and M icons will appear and the memory channel number will be indicated on the display.
3. Rotate the channel selector, or press the UP/DOWN keys, to select the desired memory channel number into which the setup data from the VFO mode will be copied. An empty channel is indicated by a blinking M. This can be useful for allocating memory channels. For example: 0-9 for local repeaters, 10-19 for local simplex, 20-49 for repeaters within the area, 50-79 for backup repeaters, 80-98 for backup simplex. This makes the memory organization clear for operation and future modifications of the memory channels.	setting an unregistered channel
4. While the F icon is displayed, press the MW key. The VFO settings will be copied to the memory channel and a beep will sound. Memory channel data can be overwritten if a preprogrammed channel is selected (not empty channels memories are indicated on the display by a non-flickering M icon). 5. To program the operational channel (channel quick access) CH-C is selected. Reserve channel Ch99 to store the data used for the “ALARM” mode, which will be explained later. Use PL and PH to program scan parameters, which will be explained in the Advanced Features chapter. 6. To delete a programmed channel, select it in memory mode, press the FUNC key, then press the MW key while the F icon is displayed. A beep will sound and a flashing M icon will indicate that the channel is now empty. 7. Cancellation of deleted channels (recovery of data deleted in point 6).

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 operational channel frequency 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 selector 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 the CALL mode. 3. In CALL mode, no viewing functions are available. 4. Use the memory programming commands to store the desired data in the on-line channel. 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.

Signal reception

Make sure that the antenna is connected to the radio, the transceiver is turned on, the volume and squelch levels are set to the required levels.

Select the reception frequency you want, or frequencies to view the channels you need to listen to. The S-meter indicates the signal level between BUSY and FULL when the transceiver detects an incoming signal.

If the S-meter indicates a signal, but no sound is heard from the speaker, check the volume level, squelch level, and the set CTCSS / DCS decoding parameters, the settings of 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 tone 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 have the right to operate on this frequency. Check the absence of a signal so as not to interfere with the correspondents who are radioing on this frequency at this time. 2. Select the transmit power. Press the FUNC key, then press the CALL key while the F icon is displayed. By pressing the CALL key, one of three power levels can be selected. The Lo icon means low power, Mi is 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 setting is high power. Press the PTT key on the microphone to transmit, release to receive messages. During transmission, the power level is shown on the radio display in segments. LOW POWER = 2 segments, AVERAGE POWER = 3 segments, HIGH POWER = 5 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 drain the battery intensively. Check battery voltage frequently. Also, the current consumption increases significantly when the headlights, stereo system, air conditioner and other auxiliary systems of the car are on. If all these systems are turned on, then the output power of the transmitter is reduced, so some of them are turned off to reduce the load on the car's battery. Control the situation on the road while working on the road. Check local regulations for the use of radio frequencies and mobile radios in the area.

Parameter setting mode

Important: Please read the following pages completely before changing any settings.

PARAMETERS CANNOT BE CHANGED WITHOUT ACTIVATED INSTALLATION MODE.

In setup mode, some of the radio parameters can be changed to suit your needs. Options are selected from the options menu.

Please note: Alphanumeric channel labels will not be displayed in the menu unless they have been programmed in advance!

2. Rotate the channel selector to select the desired setting. 3. Press the SQL or UP/DOWN keys again to enter the selected setting into the radio's memory. The transceiver is now ready for additional parameter adjustments. 4. Press any key except SQL/UP/DOWN to exit the parameter setting mode. The only exception is the alphanumeric channel labeling mode, to exit from which you can only press the PTT, FUNC, MHz and TSDCS keys. Details and features of the parameter setting mode menu The specifics of the setting procedure for some of the parameters are explained later in more detail.

Setting the channel pitch The channel pitch is selected in VFO mode. Refer to the chart below for actual cadence.
Type The scan type allows you to select one of the conditions - scanning by timer (TIMER) or by the presence of a carrier signal (BUSY). Timed Scanning allows the radio to resume scanning 5 seconds after finding a busy channel, regardless of whether it is still busy after 5 seconds. In a BUSY scan, the radio resumes scanning only when the channel has ended transmission and no signal is displayed. Scan modes are explained later.
Sound signal Beep is on when BEEP-ON is set. This means that some keys will beep when pressed. When set to BEEP-OFF, the beeper is disabled.

TOT transmission time limit

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 according to the requirement of repeater systems, the radio notifies the user with a beep 5 seconds before the end of this time. When the time expires, the transceiver automatically stops transmitting and switches to 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 transmission sessions TOT Penalty

When the TOT mode is set, this function prohibits transmission if less than the time set in this mode has elapsed from one press of the PTT to the next.

.....

Auto Power Off Mode APO - OFF

In this mode, the transceiver automatically turns off. This is useful for the mobile station to avoid running out of the car battery. If there is no radio communication, after 30 minutes a beep will sound and the transceiver will automatically turn off.

Ringing tone frequency

This mode allows you to activate the work of some repeaters or correspondents that are in standby mode by giving an audible tone of a certain frequency. Normally, the repeater system does not require a tone if the repeater is active.

Blocking transmission on a busy BLCO channel

This feature 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:

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.
LEXT	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 LEXT 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	MC	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	MR	ON	ON/OFF	When ON, causes the TNC to display the entire digipeat list for monitored packets.
MYCALL	MY	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	PE	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 acknowledgment 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	SE	$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.
UNPROTO	U	CQ	CQ	Specifies call signs to send a packet in Unprotocol mode. Call 1 is the call sign of the destination. Call2 to call9 are call signs of stations to be digipeated through.
XFLOW	X	ON	ON	Causes the TNC to perform software flow control when ON, or hardware flow control when OFF.
