Yeah true words Al. With the previous Windom I had RF in the shack on 40M especially with the desk mic. NOW I think some ferrites on the USB connections will work. I noticed during CQWWSSB that on 20M, I would space-bar the Contact into N1MM+ prior to making contact. When I transmitted, the Exchange Fields would clear, the frequency display would clear and after transmit, I'd have to space-bar again after contact. A minor adjustment that I'd like to resolve.
This antenna I made myself using formula and two direct measurements. I like that it resonates better on the lower end. And 80M seems to load up better too. The CQ WW RTTY will be a great test of the antenna though, higher or maybe tighter duty cycle will be the 'tell of the tale'.
My TL922a repairs are mostly finished including new tubes except for a few final connections. I was going to go thru with a few mods but after reflection, I will press it into service as is. Some testing will now ensue after a final review of my work. If I get +1KW output, I won't question what's wrong until I get to the CQ WW RTTY or maybe the WPX.
Looking forward to the Winter Contest Season.
Ciao Brother!
