Re: T/R Switching
Hi Jim,toggle quoted messageShow quoted text
One of the solutions which springs to mind is the "Magic Box" an excellent example of one of the 4SQRP kits, check it out on the website. One other solution I have used in the past is a single transistor driven C/O driving a relay, don't forget to put a couple of back-to-back diodes across the RX input to help limit what the RX sees. I can't guarantee it's safety with the good ole '857 though. There will be others on here who will no doubt offer more accurate and up-to date advice. Do ckeck out the "Magic Box" though, as a standalone solution to T/R switching it's neat.
