All modifications are made at your own peril and risk!

Good old Alan 78 Plus. This radio station is well known to everyone who is familiar with the civilian CB band. This is, one might say, a hit of past years. But everything flows, everything changes; in order to reduce costs, radio production is being transferred to China and the Philippines, which entails certain consequences for quality.

This happened with Alan 78 Plus. The production of the once well-designed and fairly decently functioning radio station was transferred to the Middle Kingdom, transferred from output components to a modern element base, but this did not reduce the problems. Let's start fixing them. I remind you that all modifications are made at your own peril and risk! Modern Alan 78 Plus Multi are quite unstable and require an extremely careful approach when modifying and repairing. Be extremely careful when performing operations. Some old problems of the Alan 78 Plus, which were described earlier on the Internet and Fido, have already been corrected in the new models and do not interfere with life, so I did not consider them in the framework of this article.

Modulation improvements

I would like to start with an eternal problem. How we are heard during the broadcast. And although the Alans have very good modulation, as they say, “out of the box,” we will make it even better!

For fans of extremely loud modulation in AM, you can perform another operation to disable the AMC system. The peak power of the radio station after such modification will reach 16 watts, but at the same time, at loud sounds, people who use automatic noise suppressors will have problems receiving your broadcasts, since at loud sounds the noise suppressors for your pumped-up broadcast will close.

Improved intelligibility

If you are satisfied with the quality of reception, do not touch anything.

Refinement of the threshold noise suppressor

Like all other Alans, the Alan 78 Plus does not have hysteresis in the threshold noise suppressor, as a result of which in threshold states the system begins to hiccup, randomly open and close at high speed. The fix is ​​quite simple. You only need to add 2 parts, a capacitor and a resistor. The resistor value is selected according to the device, to obtain a hysteresis of 6-8 dB, or by ear, over the air.

If you do not have enough range of adjustments for the noise suppressor knob, then you need to replace one resistor and adjust the operation of the threshold noise suppressor with a trimming resistor.

In older versions, the squelch clicked when switching from transmitting to receiving, but in new versions of stations this glitch has already been corrected.

Improved backlight

If you, like me, are annoyed when the backlight of a radio station dims when it goes into transmission, then you can install a stabilizer to power the backlight LEDs. For this, a regular LM7809 is suitable, which is included in the standard way in the circuit instead of a primitive resistor.

Alan radios are reliable and durable car radios operating in the civilian range. They are created using the latest modern technology; device parts are made of high-quality materials using semiconductor circuitry based on a durable board. The setup and installation of these sensitive devices must be approached wisely. Let's figure out what needs to be done first.

Before installing this brand radio, please determine the installation location in your vehicle in advance so that you can use it comfortably and safely in the future. The radio set comes with fasteners, with which you can independently fix the radio in the car.

Setting up the radio Alan:

• First of all, you need to connect the microphone device; to do this, you need to plug the plug into the corresponding connector on the device;
• The next step is to check that the antenna is firmly connected to the radio;
• Next, the knob of the automatic noise reduction system “Squelsh” (SQL) must be turned counterclockwise until it stops;
• Now you can turn on the radio, adjust the volume and select the channel you want to use;
• Taking into account the noise level, you can set the SQL threshold;
• To transmit a signal, you need to press PTT and then speak into the microphone device;
• To receive a signal, you simply need to release the PTT button and do not hold it.

If for some reason you were unable to install or configure the radio station yourself, you can always use the services of our qualified specialists at any stage of installation or programming. Our staff will provide you with professional assistance.

This is a low-price civilian radio, a good option for use on the highway and on trucks. The Alan 100 radio station has sufficient power of 8 “allowed” watts and allows you to work in an expanded mode of channels with “zeros” and “fives”. It is worth noting that the market is flooded with Chinese counterfeits, which cause a lot of problems for car owners; we strongly recommend purchasing CB radios from official Midland dealers.

Among the frequent malfunctions of the Alan 78 Plus, it is worth highlighting the failure of the power supply circuit (the fuse is lit) as a result of polarity reversal or the supply of 24 Volt voltage in the truck. The volume and squelch knobs are also the cause of audio dropouts or constant noise. Over time, the quartz filter of the amplifier breaks down and requires replacement. The output stage does not have sufficient cooling and can quickly overheat and burn out if there is no antenna on the car or its malfunction.

The Alan 78 radio station has a simple layout and uncomplicated circuit design; in the vast majority of cases, replacing faulty elements can be done independently if you have experience working with a soldering iron. In this case, replacing the volume potentiometer or noise suppressor, as well as the UHF transistor or the “protective” diode of the power circuits will not cause difficulties. If independent repair is not possible and the question arises where to repair the radio in St. Petersburg or Moscow, please contact us.

Frequent faults of Alan 78 Plus:

• wear and tear on the volume and noise control knobs
• no reception - quartz filter is destroyed
• The fuse is on - the result of an incorrect connection
• no transmission - UHF transistor has failed
• no sound - speaker or ULF malfunction

Typically the transceiver is located under the instrument panel above the transmission tunnel. Do not install the transceiver in the path of a heater or air conditioner. Select the optimal location for installing the transceiver and, using the mounting bracket, mark the holes for the mounting screws.

Before drilling holes, make sure you do not damage the vehicle's power cables. Secure the bracket with screws or self-tapping screws with spring washers. Connect the red wire with the transceiver power cable fuse holder to "+" power supply (best to the auxiliary contact of the ignition switch), and black - to "-" (to the car body). To connect the transceiver, you can use a cable with an adapter to a car cigarette lighter (not included). Install the antenna and connect it with a coaxial cable to the antenna jack of the transceiver. If you decide to use an additional speaker in your car, then install it in a convenient place and connect it to the socket EXT. SPKR.

Replacing the fuse

The fuse is released from the holder by pressing and turning the housing. Use only 2A fuses for replacement (one spare fuse is included with the transceiver).

Antenna installation.

Place the antenna as high as possible.

The longer the antenna, the better the transceiver will perform.

If possible, place the antenna in the center of your chosen surface.

The antenna cable should be located as far as possible from sources of interference such as ignition or measuring instruments.

Make sure the metal-to-metal grounding is secure.

Be careful not to damage the cable when installing the antenna.

Warning. To avoid damage, never turn on the transceiver without a proper antenna. Check the cable periodically.

3.3. MICROPHONE.

4. INFORMATION ON THE DISPLAY.

Your radio has a built-in LCD display that shows the channel number and operating mode.

Note: Due to its physical characteristics, LCD displays should not be exposed to extreme temperatures and humidity. If the unit is exposed to temperatures below -20°C or above 60°C, the LCD display may temporarily lose its functionality and, in some cases, be permanently damaged. Do not expose the radio to extreme conditions, such as leaving it in a closed car in direct sunlight or prolonged frost.

The LCD display has a preferred viewing direction where contrast is maximized. This direction depends on the temperature and condition of the batteries and is found empirically - by slightly changing the orientation of the radio station relative to the operator.

5. INSTALLING THE TRANSCEIVER.

Safety and ease of use are the main requirements that must be considered when installing any mobile radio equipment on a vehicle (boat). All transceiver controls must be accessible to the user so as not to interfere with driving. Make sure that the connecting cables do not interfere with the use of the brake, clutch and gas pedals. It is also necessary to take care of the comfort of passengers (for example, will there be enough legroom). An important requirement is also the speed and ease of removing the transceiver from its installation location when maintenance and configuration are necessary.
