Folks, I seem to have a new problem with my Paragon. It transmits spurs 600 Hz above and below the carrier about 10 to 20 dB down from the carrier. This was reported to me by someone using the spectr
What mode are you running? If AFSK, how are you creating the shifts? 73, Mike N4NT _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.co
This happens in Tune or CW. I can't generate a pure enough sinewave to measure in SSB, but will next week. I took some data on receive this morning and the spurs are down at least 40 dB on receive. I
Joel, What was the input voltage to the Paragon? I think it maybe sensitive to input voltage. Before I retired it, I ran mine off of a 13.8V supply and never had any complaints about my TX purity, no
Mike, Well, I went to measure, just to be sure, and everything was as expected - voltage wise. What surprised me was that the problem has now gone away. I would attribute it to contact resistance bei
Hi Joel, You'll notice from the pictures on the link I posted that the spur content was a function of frequency as you might expect from a multi-loop synthesizer. You might want to check several diff
Joel, Seems to me awhile back someone said problems with their (minor?) loop board causing spurs, and the usual resolder job took care of it. I tried a search and couldn't find anything, nor can I re
