TX DUP signal problem 200D?
Posted: Fri Oct 05, 2018 4:55 pm
After several years of relatively problem-free use of my 200D I recently have a problem (or maybe not?) with a very poor quality TX signal as seen on the DUP panadapter. When I hit tune, I see many spikes either side of the main frequency- I have attached a screen shot to show an example on 40m. I have re-loaded the firmware (v4.9) and PSDR (v3.4.9), which made no difference at all. Now, the strange thing is that when I have asked for comments on my SSB signal quality, every response has been that it is a good clean signal with excellent audio! So, this makes me question what I am seeing in the DUP window.
So, my question: is this a real TX problem (something physically broken) or is it a fault in the DUP panadapter display of my TX signal? And, how would I be able to check this?
Any help appreciated.
