SOURCE: Galaxy DX 959. SSB

on ssyou are some what familiar with working on radio's. just make sure before you pull your hair out aligning the radio that you made sure it definitely is not tx on ssb. b the.Mic gain will increase the modulation. it could just be a meter issue. confirm this by having some one on another radio on ssb the same channel listen for you. if he cannot hear you then the ssb is blown out.sounds likelike

Power drops on galaxy dx 959 when switched from ssb to am and back

if you mean that the power drops from ssb to am then when you change it back what you should do is check to see what power you have to begin with.you may have to go inside the radio to adjust the power. there is hi power and Low power so watch yourself.

Galaxy DX 959. SSB doesn't seem to work. The power meter needle moves in AM but not in SSB. I tried adjusting the bias between test points 7 & 9 to 50 mA via VR12, but can only get it down to 90...

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.

Just want to know if i should use my ll203 amp in am or ssb mode when running with a cobra CB radio?

What radio?? Does it have single side band(SSB)? If not, then don't use SSB.

AM - amplitude modulation
SSB - single side band.

If you have SSB, there would be a switch on it to transmit in SSB. If not, it is AM only.

Second, Has this radio been worked on to be able to run on an amp? If not, you will blow the amp.

A CB radio transmits dead keys with 4 watts of power, and transmits with 4 watts of audio.

a 4 watt dead key is too much for a linear amp. You will smoke the transistors. Also, 4 watts of audio is not enough to drive it properly. You won't get full power.

The dead key needs to be around 2 to 2 -1/2 watts,or what ever makes the linear dead key half its peak wattage., and the modulation (audio) turned up all the way.

It doesn't sound like you know too much about CB radio's. Not a big deal, you can learn. For right now you may want to take it to a cb shop and tell them you want a peak and tune, and set up to run a linear.

You can find CB shops usually at truck stops. Some area's they are other places. Check the internet for local shops.

Radio has 10 watts on side band

Readjust your load coil. You should never attempt this without a load and a watt meter.
