You'll need to connect Frequency Counter to C252 & adjust:

USB Frequency: 10.6975Mhz adjust L126 in receive mode
LSB Frequency: 10.6925Mhz adjust L127 in receive mode

Just got a ranger rci69ffb4 CB radio. I do not know how to operate it. What band number to put it on to talk. There is 1-7 on it. And do I put it on an or ssb mode. Thanks


If you want to talk on AM put it on AM if you want to talk on SSB then put it on SSB. Did you recently purchase this radio? You do realize you need a ham radio license to use this ?If you are on the upper ham bands you better have a license or they will come and get you .Look at the the dial that has 1 - 7 on it. Now take the owners manual and look at the diagram of the knob . It should say something about frequencies and the frequency you need to operate on is from 26.965 to 27.405 MHZ .

Transmitter Frequency alignment


look I'm going to tell you now. If you have no idea where to measure the voltage then you shouldn't be playing with that radio. First ,you need a scope,a frequency counter,a distortion meter,a signal generator,a watt meter,a voltmeter,a sinad meter and patience. If you have none of these then don't mess with it.

Galaxy 979 SSB Modulation Problem Voice Cuts Out.


It sounds like you had a cold solder joint. Leaving it in the sun probably temporarily corrected it. I would take it to a tech to have all the solder joints corrected, unless you are handy with a soldering iron. The problem will most likely come back.

All you have to do is pull the top cover off, which will show the bottom, or trace side of the board. Using a soldering iron, make sure any solder joint that doesn't fully look soldered and make sure the solder is fully covering the joint. If need you may have to add solder.

As for the frequency counter going nutty when you modulate, Don't worry about it. There is nothing wrong. Because when you modulate you are modulating the carrier signal you are changing the signal so the counter will interpret that as a different freq because it cannot differentiate. Freq counters are for use with carrier only. As long as the carrier shows correct, it is right.

How do i adjust the sideband


Instructions

Connect one end of your coaxial cable to the output port on your SSB Transmitter. Connect the other end of the cable to the coaxial input port on your RF demodulator.

Connect one end of your 1/4 inch audio cable to the audio output port on your RF modulator. Connect the other end of the audio cable to the audio input jack on your amplifier.

Turn on your SSB transmitter, RF modulator and amplifier. Adjust your SSB transmitter modulation by adjusting the knob on your RF

SSB off frequency


Hi, my name is John. Welcome to FixYa. It will take a tune-up that involves some expensive meters. The tune-up should be only about $35.00 to $45.00. The 148 is a great radio, I have three myself and they are great. Only your local licence tech. can do it, or any CB shack. Good luck and thanks for choosing FixYa...John

Symptom:Buzzing or motorboating sound in either the transmit or receive.
Problem: TR602 is oscillating
Cure: Replace C602 with a .01uF cap {Cap is located in the power supply board}.
RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.
