And although, at the moment, the relevance of this radio station is functionally very low, I decided to review it. It's still a living representative of the old school of building CB radios. Some may like it, some may not, but one thing is for sure, this station has charisma. Perhaps someone is still using the same, or an upgraded version with the Multi prefix and made on SMD components. This device is from my personal collection. This station is also dear to me because it was from it that my path to the world of CBS began.
Yes, yes, this is the same radio station that I described in the "" section. Alan 48 Excel bought in the mid-2000s and still alive today. I carried out a number of operations on it to improve its characteristics, and I am compiling this review as some kind of tribute to this device, which has become a guide to the world of radio for me.

Appearance
The station has a classic design of the front panel, similar to the design of the devices of the American company Uniden.

Compared to modern stations, the body is quite decent in size, it certainly does not overtake American CBS, but it cannot be called small either.


The case is painted with black powder paint. The top cap features the Midland logo and CB TRANSCEIVER logo.


The front panel is made of plastic. It is quite soft and scratches easily. On the front panel there is a transparent insert covering the LCD display and S-meter. In this station, the S-meter is made in the form of a pointer device, which is quite convenient, since it allows you to track slight changes in the input signal visually.


The S-meter scale also serves as a scale for evaluating the output power of the radio.
On the left is the channel changer. Under it is a headset connector, it has an original shape. Such connectors are placed only on the Alans-Midlands. It does not give any advantages, but it looks aesthetically pleasing.


Under the S-meter is a button for switching the operating modes between the mode - the radio station (CB) and the mode - loudspeaker (PA).


To the right are two indicators. One is responsible for the indication of reception and transmission, the second for the indication of the modulation mode.
To the right is an LCD display that displays the channel number and grid. It has a nice amber backlight. It is read only from the front and top, it is poorly read from below.

Outcome
As I already wrote at the beginning of the review, it is impossible to give an unambiguous assessment of this device, some may like it, some may not. One thing is for sure, for its time the device was good. Now it is already obsolete. Despite this, they continue to be released, both regular Alan 48 Excel and Alan 248 Excel on SMD with nasty blue backlighting. This says a lot, and most importantly, there is a demand for it. I don’t know what the consumer is pecking at, but the stations are sold, and from time to time appear on the secondary market, and are even sold there.

I will say this, at the moment, if you need a station for work, I would not advise you to take Alan 48 Excel, especially a modern one. But if you liked this station, and you take it for the soul, I think you will not be disappointed.

Governing bodies

The Alan 48 Plus radio has a simple and easy to remember control, thanks to the fact that the manipulators and buttons are grouped on the panel according to the relevance of their use.

Channel switching is done with a potentiometer CHANNEL – it has a clear, fixed stroke, without any backlash. The switch handle has small notches to prevent slippage in the user's fingers when switching.

In two oval niches located under the display, there are 4 regulators:

-ON/ OFFVOL- enable/disable the station and adjust the volume of the speaker;

- SQUELCH– regulates the operation of the threshold noise suppressor;

- RFGAIN- using this potentiometer, you can adjust the sensitivity of the radio receiver;

- MICGAIN- allows you to adjust the microphone gain to transmit the most natural voice message on the air, cutting off external noise around the correspondent;

The travel of the regulators is smooth, with a linear effort. As well as on the channel switch, each knob has small notches around the circumference.

Next to the display are buttons responsible for working with the station memory. (M1…M5), red key EMG for a quick transition to an emergency channel.

Buttons Q. U.P. and Q. DOWN oblong shape, carry out a quick switching of channels on the grids of the station.

Two large oval buttons switch modulation modes AM/ FM and turn on scan mode SCAN.

All buttons are backlit.

Thanks to convenient vertical switches, the user can switch the station operation mode on the air or in the "megaphone" mode (SV/RA), control the operation of the impulse noise filter (ANL) and quickly turn on the reduced sensitivity mode of the radio receiver (LOCAL/ DX) The latter function can be especially useful when communicating between correspondents at close range, for example, while moving in a convoy or when receiving strong signals.

And although, at the moment, the relevance of this radio station is functionally very low, I decided to review it. It's still a living representative of the old school of building CB radios. Some may like it, some may not, but one thing is for sure, this station has charisma. Perhaps someone is still using the same, or an upgraded version with the prefix Multi and made on SMD components.

Appearance
The station has a classic design of the front panel, similar to the design of the devices of the American company Uniden.

Compared to modern stations, the body is quite decent in size, it certainly does not overtake American CBS, but it cannot be called small either.

The case is painted with black powder paint. The top cap features the Midland logo and CB TRANSCEIVER logo.

The front panel is made of plastic. It is quite soft and scratches easily. On the front panel there is a transparent insert covering the LCD display and S-meter. In this station, the S-meter is made in the form of a pointer device, which is quite convenient, since it allows you to track slight changes in the input signal visually.

The S-meter scale also serves as a scale for evaluating the output power of the radio.
On the left is the channel changer. Under it is a headset connector, it has an original shape. Such connectors are placed only on the Alans-Midlands. It does not give any advantages, but it looks aesthetically pleasing.

Under the S-meter is a button for switching the operating modes between the mode - the radio station (CB) and the mode - loudspeaker (PA).

To the right are two indicators. One is responsible for the indication of reception and transmission, the second for the indication of the modulation mode.
To the right is an LCD display that displays the channel number and grid. It has a nice amber backlight. It is read only from the front and top, it is poorly read from below.

Below the display and the S-meter are the control buttons. They are also highlighted and I will talk about them in the functions section.
On the right side are 2 double handles. Top volume control and squelch adjustment. Below is the microphone gain and receiver sensitivity adjustment.

The handles, like the display, have an amber backlight around the perimeter, like BMW's angel eyes. The backlight is not bright. This is convenient and makes it easier to search in the dark.

The headset is small and light, it gets lost in the hand, which is not very good. However, it is quite reliable and works well.

There is a serial number label on the rear panel. Antenna connector. Socket for connecting an external S-meter.

External speaker socket (PA) and external speaker socket (CB). The power cord has a quick disconnect connector, which is a plus.

Functions
The station has 10 grids from A to L. Each grid has 40 channels. Total 400 channels. Channels and grids are displayed on the LCD. There are also 2 types of modulations AM / FM. The modulation is switched by the button with the inscription M4 (AM / FM). Which mode is enabled can be judged by the color of the right LED under the S-meter. Red - FM, green - AM. The transmit-receive mode is also displayed on the LED next to it. The principle is the same. Red is transmitting, green is receiving.

The S-meter has two scales. The top one shows signal strength in points, from 0 to 9+30. This is typical for civil band stations.

The CB/PA button turns off the radio and turns on the external speaker under the hood of the car if you have one installed and connected to the PA jack on the back of the radio.

Radio control buttons

FUNC button - allows you to record channels in memory. A total of 5 channels are available for recording. To memorize a channel, press the FUNC button and press and hold any button with the letter M*. Thus the channel will be recorded in memory. You can call up a channel from memory in the same way by pressing the FUNC button and briefly on the desired M * button.
Button - EMG. Switches the station to 9 and 19 emergency channels.
Button - DW. Enables dual channel listening mode.
Button - SCAN. Enables channel scan mode.
Button - AM / FM. Switches the modulation. The modulation indication is described above.
Button - Lock. Includes keypad lock and channel knobs.
Button - N.K. Enables Noise Killer mode. Works strange, in fact, cuts off high frequencies, highlighting the voice from the noise.

Adjustment knobs
They are on the right. On top is the volume control knob, it is inside, and the threshold squelch control knob, on the outside. There is only one in this station. On the bottom is the microphone gain control, inside, and the receiver gain control, outside.

Inside
The station is made on a printed circuit board made of yellow textolite. This is an old version built on output components.

SMD is used here only on a separate ESP (Noise Killer) board.

According to tradition, the VUN, like all Alans, is filled with paraffin. This is the weak point of the station.

Paraffin is designed to bind parts and protect them from rattling, but in practice, it turns out that the coefficient of thermal expansion of paraffin and solder, with which parts are soldered, is different and with temperature changes, paraffin slowly loosens and pulls components out of the board, destroying soldering. This must be remembered if you suddenly lose reception or transmission. First of all, look at the GUN. The output stage is built on bipolar transistors 2SC2314 and 2SC1969. They are screened. It’s a problem to get the latter now, but if you still managed to burn them, then they can be easily replaced with 2SC2078 without any alterations and power loss. Otherwise, there is nothing particularly remarkable inside the station, it is built according to the classical scheme, and if you close your eyes to some shortcomings, with careful operation, it is quite reliable.

Truck drivers in their work constantly use radios cb range 27 MHz. Historically, in all countries of the world they communicate on one specific channel. This radio can be used as such walkie-talkies for truckers. And since these walkie-talkies have a large number of channels (400), they are very often used as taxi radios.

In the car, she was replaced by 78+, she was struck by the sound of the speaker - completely deaf, upset. Traveled for a while, replaced back to 78+. Then somewhere I found information on how to change the sound of the speaker. The operation was done and the station settled in the car.

Strongly finished off the lack of memory. the meaning of the buttons of the memory cells is lost, each time to set everything up again, I stopped at the tent / store to buy water and everything again flew off, turned it off and on, everything flew off. As a result, improvements were made:
1. Power supply - capacitors C434, C702 are thrown out, an ionistor is installed at 1000F 5.5V. Holds more than a week for sure, maybe more, but there was simply no downtime.
2. Zeros and fives were made by the seller by switching the processor (holding the PTT and turning on the station will be zeros). But after all, I made the memory of p.p.1 i.e. goes switch will not work, but the solution was found quickly. We cut / solder the jumpers from the ANL switch and connect the ground to it on one contact and the 68th leg of the processor on the second. As a result, in one position of the switch, the memory is saved, in the second position, the processor starts with a reset and, by polling the state, turns on the desired mode. I note that when you start with a reset, all memory is erased :(.
3. They rarely complained about modulation, but they redid it. I soldered C456 and soldered a 4700pF capacitor between 1 and 5 legs of IC104
4. I switched the SCAN button to scan memory cells, it's more useful for me.
5. I connected the signal for voicing the keys and turning the encoder, the signal from leg 7 of the processor through a 220K resistor and a 0.01 mF capacitor was fed to the ULF input (pin 5 of IC103). But this is for me and the fact that the station is in the car. If for the house, then you need to apply to the upper (according to the diagram) output of the volume control. Then the volume of the signal will change depending on its position, for the car it was irrelevant for me, more precisely, it’s even important that the beep be as loud as possible.

By the way, the memory there should generally be supported without alterations, if the station is connected to the power supply all the time, the processor is fed bypassing the switch. Does not work due to a sharp jump in current consumption at the time of shutdown i.e. they didn’t think of something, in a simple version it’s enough to put a larger capacitor. I tried to keep the memory at 500mF for 10 minutes, although the capacitor was some kind of ancient, it is possible that its self-discharge current was more than the current necessary to maintain the processor memory :).

Among the shortcomings of my copy is a very high signal level at the ULF input, it is unrealistic to use the station at a volume of more than 14 hours at the regulator position, it yells loudly and there is too much distortion, you can make out what they say, but it’s very difficult. So far I have not dealt with this problem. Yes, and recently engaged in a large number of improvements. The main thing was the humming of the speaker.

Pros:
- Sensitivity adjustment is very useful.
- Quite a good sensitivity, who complains, try it on different antennas, I checked, there are very significant differences.
- Good volume (even unnecessarily).
- Availability of memory cells.
- After the alteration, scanning by memory cells.
- Height 1DIN.
- The possibility of some increase in power, but I do not need, there is something to increase :).
- Captures the 10 meter range.

Minuses:
- Threshold noise reduction.
- Ergonomics, I would tear off the hands of the one who came up with this. The volume control next to the massive PTT connector, well, it’s very inconvenient to turn, there is also a channel switching wheel (valcoder). That is, those things that are needed most often are just the most hidden, although they seem to be in plain sight.
- The height is 1DIN, but the width is not. Stupidly inserting into a one-din place will not work.
- The station is very deep, in a couple of cars I barely screwed it in, and then with the help of files and other similar things - I couldn’t fit it. Another thing is that, nevertheless, it is 1DIN in height - it is easier to attach than something that does not correspond to the size at all.

In general, if I were offered the same thing now with automatic (spectral) noise reduction, then I don’t need anything else. Although no, the AM-FM modulation would still be remembered in the cells, then nothing more is needed for sure.

So, in my opinion, the station is quite balanced in terms of functionality and quality both in the car and as a base station. At the reception, it works for me a little better than ALAN 78+, although this is already faintly perceptible. Compared with some other stations of the same class - I did not see any difference. In comparison, there were megajets and yosans.

Alan 48 Plus Midland Controls

The Alan 48 Plus radio has a simple and easy to remember control, thanks to the fact that the manipulators and buttons are grouped on the panel according to the relevance of their use.

Channel switching is done with a potentiometer CHANNEL – it has a clear, fixed stroke, without any backlash. The switch handle has small notches to prevent slippage in the user's fingers when switching.

In two oval niches located under the display, there are 4 regulators:

—ON/ OFFVOL- enable / disable the station and adjust the volume of the speaker;

— SQUELCH– regulates the operation of the threshold noise suppressor;

— RFGAIN- using this potentiometer, you can adjust the sensitivity of the radio receiver;

— MICGAIN- allows you to adjust the microphone gain to transmit the most natural voice message on the air, cutting off external noise around the correspondent;

The travel of the regulators is smooth, with a linear effort. As well as on the channel switch, each knob has small notches around the circumference.

Next to the display are buttons responsible for working with the station memory. (M1…M5), red key EMG for a quick transition to an emergency channel.

Buttons Q. U.P. and Q. DOWN oblong shape, carry out a quick switching of channels on the grids of the station.

Two large oval buttons switch modulation modes AM/ FM and turn on scan mode SCAN.

All buttons are backlit.

Thanks to convenient vertical switches, the user can switch the station operation mode on the air or in the "megaphone" mode (SV/RA), control the operation of the impulse noise filter (ANL) and quickly turn on the reduced sensitivity mode of the radio receiver (LOCAL/ DX) The latter function can be especially useful when communicating between correspondents at close range, for example, while moving in a convoy or when receiving strong signals.

Tangent

It is small in size and fits comfortably in the hand. It is connected to the station with a twisted wire with strong and elastic insulation that does not harden or crack when used at low temperatures. The microphone is of the electret type.
