Re: TVI and the "ARC-5"
Dave Stinson is our "go to" man on this question.
Some time ago, with Dave's input, permission, and assistance, I compiled some information he had provided to the ARC5 forum in e-mails concerning several matters regarding the transmitters.
Not only how to build a correct power-supply for them, but how to correctly connect them to an antenna, how to prevent chirp, how clean or dirty they were with regard to TVI, etc.
He provided details. The transmitters are "unusually clean" (his words).
He had come to the conclusion that any TVI experienced from the ARC-5 transmitter was most probably due to issues at the TV receiver, like 21 MHz I.F.s, fringe reception, etc.
After preparing two documents containing Dave's info, I then published those on my website
www.w7ekb.com/Glowbugs
Since that time, I have found those documents on some others' websites, but with never any "attribution" of their source...
which I consider to be, at least, impolite.
Still, as long as our community benefits from the info, where-ever they find it, I am happy.
