I have a homemade K9AY loop with the classic diode setup to pick direction remotely. Unlike the classic switching scheme with Bias-T's, I use isolation transformers at both ends to couple switching v
So what is killing these simple semiconductors? Thinking about removing all semiconductors and running independent switching wires. How is the RF bypassing and layout? _________________ Topband Refle
I think you raise a good point Tom. I know I have some RF in the shack especially when running the amplifier on 10M which has been happening a lot the past few months. The computer sometimes reboots
The antenna end of mine, looks very similar to PG0A/PA3FYM implementation, drawn at http://remco.org/wordpress/wp-content/uploads/2008/01/pg0a-k9ay-small.jpg Uses an isolation transformer (not an aut

Is there a better way to use an isolation transformer to couple relay control voltages over the coax? Or is it as simple as, Bias-T's are always best, and there's no good way to do it with a transfor

"Things like this are not rare. Simple circuits can have multiple modes of operation that are hidden from view on a schematic. A page linked on not using MOV's on power lines is similarly narrow focu
