Check the mic wires inside the connecter, there might be a loose or broken wire that is making an intermittent connection.

bad ground ?Look at your meter when you key and check out the number reading you get . 2.7 and below is ok but the lower the better.

It sounds like the radio wattage is cranked way up, the RF METER adjustment is not set right (Adjusting VR5 while keying the radio will fix that) SWR is VERY high or there is a break in the antenna line between the radio and the base of the antenna.

Have you checked the SWR's on the anntenna. Make sure all the coax connections are tight and not loose on the so239 connections.

with wilson antennas you don't have to need to run duals the proper way to adjust the SWR is to get an external meter like a trucker 2000 and a dummy load. you hook the dummy load to one antenna while working with the other and then switch the operation around. this way both antennas are matched seperatly yet work together.

the person is talking about a cobra 38wxst and you guys give him information on a cobra 25,but the information is solid as to what is said Check your SWR ,Make sure your squelch is open,check for dust on the knobs , and then take it to a tech and let him fix it because a receive alignment is more sensitive then a tx alignment.

its a secret

you need a signal generator that costs more the radio you want turn the squelch up on.If its a one time deal its not worth it.If you intend on repairing radios then you will have a headstart. you need a service manual.the manual will tell you which vr to adjust.

if this is a used radio its because some golden screwdriver got into it but if its a new one then its the radio.Check the reverse polarity diode in either case to see if its burnt. If so replace it and see if it happens again.
