vr16 .talk to someone and turn it all the way to the left then all the way right and have them tell you which has the better modulation.

yes you just need a pod replacment should be pretty cheap if you take it to a tech it's probabley a 1 to 2 dollar part labor will be more.

It could be your antenna or coax. Check the swr. Also check the rf gain knob. It also could be the mic. Sometimes the wires come off.check all conn. Like coax to the radio. If you still need help here is my email

If your talking at least 2 then it sounds like it is the antenna. Any antenna should talk 10-12 miles on a good day, no matter what radio you're using. So I'd get a second look at that system.

Well first you need to be shure you lost the final's. If you had a high am deadkey it's easy to kill final's but on ssb it is possable. Did you try to transmit on am? If so was there any output? If you have checked the mic and if you have a power mic checked the batt. Put a watt meter in line on am and see if there is a carrier adj. The rf power. If there is life then there could be other problem's. I do peek & tune and small mod's and repairs for myself and some local's but work is slow so I'm doing radio work to help pay the bills.

Good luck with it and 73's

How high do you want to swing? 30 or 40 feet high enough. Clip every diode you see including the surface mount ones. This mod will give you big swing.

Jeremy,how good are you at soldering? Do you have another radio you can hook up next to the 959? hook that radio to the antenna and the 959 to a dummy load.Key the mic and look at the meter on the second radio to see if it moves. If it doesn't then your soldering skills are required. You may have to replace the final and since this radio may or may not have two of the your soldering will be improving.Check out the audio transformer also.Anything in the tx audio circuit. If you don't want to mess with it get a tech to do it for you.

where that at

What is the serial number? There was a mid production change

I think it is safe to say 90% of radio problems are microphone. You get a cheap one when you by just about any radio. I believe you are seeing the meter move but not getting audio from your talkback. No matter remove the mic jack plug from radio. For you particular radio looking at the end of the jack notice the small raised numbers. These female connectors no matter the mic type wired for this radio model has the following wires connected or in your case disconnected. 1-(Ground) 2- (Audio) 3-(Transmit) and 4- (Receive).A RK56 mic would be my suggestion Astatic 636L the second choice a little cheaper but audio it not a crisp. Don't waste your money a repairing the mic or buying a diesel or road pro or even a cdl mic like a cdl 56 or that Skythumper they are RoadKing 56 wannabees. Sorry about the rant my point is RK56 is Quality.

In most cases if the mic works the common cause is the transmitter in the mother board is shorting out or not soldered to the board properly. another cause could be that your antenna is too close to the CB and will disrupt the signal.

I'm not shure if you have tried but turn the mic gain down then check the d.k output. If you still lose power after a d.k it could be a final it's hard to say w/o seeing it. Also an external meter is more stable than the internal one. Check your coax, make shure all are tight. If you need more help e-mail me at

Good luck

check the board maby you have cut or short somthingbernardhttp://www.rylwy.com/

turn off your other radio, when transmitting.

If there is no movement on the meter. have the SWR's check on the antenna system.. Free to have it checked. at a good shop.. You may have whats called a blown final..( final transmitter transistor) from high swr's. although you may hear, doesn't mean the antenna is OK. the other problems are a bad Audio transistor on the back corner, its the Large TO-264package/TO-218/TO-220 Styles. also. there a small diode on the solder side of circuit board near the 10.240 crystal, if its loose will also not let it key up or TX. make sure all your coax cables are tight, and all the switches are in the correct positions... also doesn't hurt to have a second radio nearby to see if it will transmit to it. for testing. If you need more help let me know.

• Well, AM is Amplitude Modulation and Sideband suppresses the carrier and uses only the top half (upper sideband) or lower half (lower sideband) of the wave.

• Whether using AM, USB or LSB you are on the same frequency although if someone is on USB and you are on LSB you will not be able to understand what the other person is saying because you are using different parts of the wave. So 27.185 (channel 19) on AM, USB or LSB is still 27.185.

• If you have further questions please let me know.

• If you have any comments please feel free to leave them here.

• This Galaxy was built as a CB to run on AM (11 Meter). The majority of people on the CB run AM stations. Sideband (upper and lower) is where the carrier is removed and the wave being transmitted on is cut in half. You can do this just fine but mainly if you want to talk to someone and you both know your going to be on Sideband for a little privacy. 38 LSB is a great channel to catch some DX side band on world wide. But yea, AM is the best to find people to chat with.

Heat comb or heatsink for dissipating the heat for internal component. In this case the final transistors which could be 2sc1969 older units or Mosfet 520's newer models.
This does not come on this radio from factory. Radio has most likely had another final added for additional transmit power and the heatsink is for additional cooling.

Something you need to determine is the route this rf interference is entering the radio antenna port or dc voltage supply line.

This Radio you have has a very sensitive receive circuit and i would make sure you are using a good quality well shielded coaxial cable. Perferably 95% shielded i have not found Radio Shack to be a very good source. Check a local truckstop this cable is nothing fancy and a 9ft cable should not be more than 10 bucks.

Often the electric fuel pump or the alternator are the biggest noise generators. They can be toned down by noise filters or capacitors attached at these locations. This is a good read on the subject http://www.termpro.com/articles/noise.html
