Does anyone have a link that shows the inside of a roadking mic? I have several that are in pieces and the little wires are all mixed up. I know how to wire it to the radio but not sure of the inside of the mic. There is a passive filter or something that has four wires or so coming out of it...

I have had a post on the tech section of cb with no help so here we go .....
What would cause distortion with this talkback board. I have tried everything I know to do with grounds. I tried another module and it is doing the same thing so I must have something wrong. I have gone over and...
I am having trouble with low audio from talkback and also distortion. it is a cobra 29......any help appreciated . I have played with the grounds....do you know where the resistor is that you can cut for more gain.
thanks

I got the single mosfet final that does not require replacing the pre driver. My kit was sent for a 29 cobra. So the complimintry circuit is not the right one. resistors diode and disk cap.
does anyone have the instructions for the 66 as well as the tune up.
thanks

I bought a nice looking radio at the hamfest in Jackson ms. sat.
The problem is the radio is dead..there is some sound on fm. and the panel light is on. frequency selection works but is not working on 11 meters. there are three jumpers behind front panel and I have tried most every...
which jumper unlocks 11 meters or all available channels. thanks..just picked one up and anxious to give it a test drive. I have never been around one of these.
thanks davis
I have been ask to join the local ham club. They use six meters for the better part. I have taken the practice test. And soon will have my tech papers.
Question:
what radio would you look for on ebay used. I think I want high freq plus six meters
what do you think of the sb 200...
I am trying to get the voltage down on an unregulated power supply.....it is frying pills because it is doing 22 volts at key up and goes down only to 16.
I have tried using a five watt resistor of different values both on the ac side(pri and sec) and dc side.....could some give me some...
Thanks again for your help.............I am so close to having this figured out........
What are some common reasons for high swr when amp is in the loop..I have high swr even if the amp is off. I even took all the wires of the relay except the in and out wires and still high swr. I have...
has anyone here bought the splatter combo from these guys; cleanrf.com ?
they are break out boxes for your scope. one between radio and amp....and the other between amp and ant.
the manual makes it all seem so simple to me....dunno though....
one is x the other is y on...
I just built a amp that the schematic called for a 1446 for the first stage. I had several 2879's so I used one and ended up with one 2279 driving two 2879,,,
the first thing i noticed was not enough power coming from amp 175 watts. I have a bird 43 but only have a 100 watt slug...my...
does anyone have this......I am looking for keying info .....some amps have a diode on the coil of the relay some don't.....I am burning the keying transistor. On one side of the coil there is the keying circuit.....on the other side can I just make it hot if not running var power....on this...
can you give me a good link for tune up on this radio. it has a dead key of 38 watts on bird 43 but no swing.....I used it barefoot on a trip recently and it was not getting out like it should.
any help will be appreciated....there is a guy that has a web page for this radio but I cant...
I finally broke down and bought a bird 43 with a 100 watt slug.
Does this meter only show the carrier and not any modulation?
it shows rf power up to 38 watts max. but again no modulation at any power setting ......the radio meter is showing modulation....mmmmmm
I have the arrow in the...
