Allison Well said. Are we ignoring the possibility of using series LC traps to suck out some of the bugs (bug traps...?), 8-) Arv _._

Re: Stone Soup
We probably shouldn't feed the trolls, but... I agree. I remember the 60's and 70's gear (I was first licensed in 1961 as a Novice). I'm sure those WWII surplus ARC-5 transmitters weren't very clean

Re: Stone Soup
My position is its got bugs.? So what. Fix the worst ones.? The low pass filter issue has several fixes.?? Spurs if you stay under 20mhz they are generally not a big deal. So you didn't get 10M

Re: 80 Meters Harmonics Fix Proposal

Re: UBITX TX level diagramme
To low res to blow it up to 200% and at the current size its really poor (fuzzy) to read. I'll sketch it on paper and shoot a picture if I get time.? Either that or start all over in Impress. Allison
