Hi, I have a Realistic TRC-446. It powers up with the weather side working fine, but the CB side is dead. The Tx/Rx light is off (NOT green) while in receive, turns red when I key the mike. The needle never moves, even when attempting SWR calibration. I get a good "thunk" when I switch ACE on and off, otherwise nearly silent. With volume on full, I have a bit of hum which disappears when I turn up the squelch just a bit. Any suggestions? Thanks.
 

look inside n check the so239 connection first.
 
Found this on another forum "
The trc-446 is made by MAXON & is essentially a Maxon MCB-100WXD with cosmetic
differences. The internal board design is NOTHING like any Uniden , Cobra or
Ranger CB radio. These models are well built, but don't "peak up" well &
aren't able to "do" xtra channels. A Uniden 76/78 or Cobra 29 is a much better
radio"
I don't know how factual it is though.

    I will not be there but hopefully by the end of this month I will have my New tower and antennas back in the air including my M2 6M5X. The old tower and all of my antennas came down in October 2023 during a Hurricane.
