As for the "recieving on a lower channel, transmitting on the right channel" issue I went through all the pots and switches with CRC QD Cleaner, twice.  I even had the front bezel and knobs off for better cleaning access, when I was replacing the meter.  All the switches and knobs seem to work.  No 10khz switch like on my General Lee.  This problem has existed since I received the radio, so nothing I've done so far caused or affected it.


Attached is what the front panel of this old 3300 looks like, disregard the 3300HP-ZX, it's just a photo I found on google that matches what my 3300 looks like.


I can get a photo of the component-side of the echo board later today, and maybe a close up of the backside of the front panel to see all the pots and their wiring.
