Paul, I would have a hard time blaming something like that on the antenna. Furthermore, if signals are intelligible on 40 meters, they should also be intelligible on 80 meters - the same sideband is used. Similarly on 20 and 17.
The only thing I can think of is that your your SSB filter settings are not optimized. I encourage you to use Spectrogram or a similar FFT audio spectrum analyzer running on the computer to set your SSB filters. Take a look at part 3 of the K2 Dial Calibration article on my website www.w3fpr.com for information on how to accomplish that - you might want to go through the whole process and come out with a correct dial calibration as well. The only other thing I can think of (other than filter alignment) is that you were listening to some lousy SSB signals (or AM signals) on 80 meters - some of them are almost unintelligible even with a properly adjusted receiver - but then many of them are very good too. 73, Don W3FPR On 4/22/2011 8:16 PM, Paul Agoglia wrote: > I have been testing my K2 serial 7059 on receive only today.
