Do back-to-back diodes across a receiving antenna degrade receiver performance before they begin to conduct? what I'm considering is back-to-back series strings of diodes to limit RF voltage at the f

Pete, I'm not sure if the diodes would degrade or not. Back in the 60's Drake used a small incandescent bulb across the receive ant input to absorb high amounts of RF. I had a TR3 & didn't notice any

I built a K9AY loop that uses a mini-circuits 9:1 DIP matching transformer. When first constructed, I blew out several of them whenever I operated QRO. Being unsatisfied with the performance of the t

Pete Many, many years ago, I used a separate receiver and transmitter, along with separate antennas for receive and transmit instead of using a T/R switch. To protect the receiver from the very stron
