Hi all, I am on the hunt for what seems to be a rare item. The chrome bezel for an S9 radio. the one with the large round meter. I believe that the S6 bezel would work as well. if anyone has one, or knows who might, please let me know. Also please message me with your price if you don't...

cool! i used to have the VSB-1 by selman enterprises (the secret CB people) but i never hooked it up to a radio. how about some pics of the insides of this beast! Who knows maybe i will be one of those weak contacts you can now make! LC (410)

try changing VC1 itself. LC

I like this mod since it allows you to set the range of the external pot using the internal controls. this allows you to run a 1-4 watt range or maybe a 3 -8 watt range depending on your needs. I will say however that i stopped offering variable power as an option years ago unless the customer...

they would actually perform better on a fiberglass mast. metal masts create a "leaky capacitor" to ground and can mess with radiation patterns. strength could be an issue. with the antron 99 in particular, you would want to make sure the first 9 feet of coax coming down from the feedpoint...

Shadetree, this is a perfect excuse to buy a nanoVNA to play with! LC

i worked on these before. the fets are factory as are the ceramic insulators. trying to convert it to bipolar operation could be a pretty daunting task. remember that not all details are shown on the schematics. for example, the jumpers aren't shown. also there are ferrite beads that need to...

im confused as to how the pattern looks clean on the scope with the swing mod installed? LC

the reason no one has just said "adjust x and y" is because we don't know what the actual issue is and don't want to make the problem worse or mess up an expensive radio that would then need to be sent out for an alignment. however, it is your radio and if you feel like you know what you are...

so you don't notice this problem on AM? when strong signals do come in on SSB how do they sound? like, is everyone's voice kind of tinny? bassy? there is a chance that the IF section is slightly off if this is the case. Tuning IF offsets for frequency alone can cause problems because that...

Im going to get right to work on a CB microphone that looks like a hamburger. After that i'll make the next model that looks like a cup of coffee. LC

I think the HP5381a is a great starter frequency counter for CB radio work. It will let you set things down to 1hz accuracy with a 1 second gate time which is very useful when aligning radios. yes they are very old so they should have their electrolytic caps (three of them i think) replaced in...

thank you for the suggestions! I like both the mckinley and the lincoln but i believe i wouldn't have the depth required for the lincoln. just looked as its specs and its 10 inches depthwise. if the EU mckinley is the same size as the FCC version, then its only 6 inches in depth and would be...

Hi all, Im not well versed on all the latest offerings in the CB market as i tend to enjoy/work on older equipment for the most part. however, the factory stereo in my van is starting to act flaky and im in the process of replacing it. This particular vehicle has a double DIN opening, so i...

You might need him to bring the radio and the mic he uses, and at least one of his amps so you can try to reproduce the problem on your bench. he might have some sort of ground loop issue. if that RCI base has its main PC board DC ground isolated from the chassis, he might be connecting the...

can you describe your setup including power and coax connections and also include any grounding? the more detail the better. LC

Disclaimer first. I've never messed with one of these radios, but i wonder if someone would be willing to try an experiment for me in an attempt to help this issue. (this would do nothing for a narrow receiver issue if that's the actual problem) Turn the radio on in AM mode with nothing...

does it happen when the amp is off?

I thought i noticed it happening, but it was just the AC in my house turning off. LC

Doffo, if you compare the schematics, you'll see that this circuit is eerily similar to the AM regulator sections of galaxy and ranger radios that use the 2SB754 (TO-247 style) and the 2SA473 (TO-220). they are basically the same circuits but the parts were beefed up in the later versions...
