Hi the radio internall will have a driver and final transistor these are for the output signal or tx. you might find that the final transistor is faulty and needs replacing these fail due to incorrect swr or tuning of the antenna or cable / connector shorts. dont over look a bad microphone connection wiring on either end and internally on the ptt switch

most common driver is 2sc2166 and 2sc1969 for 27mhz amm & ssb

That's usually a defective amc stage that produces RX audio and TX modulation. It's an integrated circuit that will require a tech fixing it. You will have a transmitted carrier with no modulation, and no sound in your speaker. However, make sure you have a good mike plugged in first, and substitute a known good mike to verify it's not the mike. With the WX band working, the above may not apply.

See if you have a carrier...signal going out, but no modulation. Get your Tech to check the mike wiring/circuitry inside the radio, also.

2005 Ultra Classic CB transmits fine, does not receive at all . Replaced headset and cables, no luck.


Have someone check your SWR readings (using a SWR meter) on the antenna. This should give you some information on reception.

Perhaps a faulty connector on your coax cable. Get it fixed or replaced you coax cable with a new one.
