Hi John and others, I have a couple of Amphenol transfer relays and would like some info if you can help. I have not found anything useful on the internet so far. They are:- 300-10578 328-11005-3 Both

Quite a treasure trove of bits. I have heard that pushing YIGs from 22 to 24GHz shortens their life quite a bit. It made me decide not to push my working HP8566 to 24GHz. Replacements are like rocking

Maybe we should insist on relaxation of the planning laws so our masts are high enough to put them above any human exposure. What about the Apple I phones that are outside limits? https://www.dailymai

Yes alive here. Looking for plenty of bits. A 24GHz feed for an offset dish. 47GHz transmit bits, mixer, amp, feed. Also looking at 76GHz so need a doubler 37-76GHz or harmonic mixers. Looking to scor

All, FYI. Please find below details about the Midlands RT and ATV event for 2019. For those who are new to this it is a small (ish) friendly group of radio enthusiasts all getting together to discuss/
