Hello All, I've got a TR-3 that I have a question and wish some ideas/suggestions on.
With Function switch in the SSB poistion, and SideBand switch in left (no "x") as I switch the bandswitch thru it's positions I get the following:
80 meter = with function switch left, LSB light, with function to right - USB lights.
40 meter = with function switch left, USB light, with function to right - LSB lights.
20 meter = with function switch left, LSB light, with function to right - USB lights.
15 & 10 all = with function switch left, USB light, with function to right - LSB lights.
Notice the 40 & 20 meter bands seem to be reversed. On 20 meters it seems to RX and TX ok and it's on freq with the LSB light on - and on the freq of other station. The RX & TX freq do not match exactly - or maybe I'm not tuning RX close enough - hard to get real clear as my 756Pro does.
If the Function Switch is moved to right ("X") position voices stay distorted as normal for wrong side band.
I was thinking it might be simple as a couple of wires crossed, but I look at the schematic and it sure looks like the S1a and S1b (front & rear) switches share most of the wiring from the USB/LSB lamps with the function switch taking a wire to ground depending on selection. My schematic is not very clear with some numbers/letters not legible.
Any ideas or suggestions of where to start? What could cause this?
