Hello Power People, I have an Alpha 86 where something has failed resulting in a fault. Since this failure mode began very shortly after the amp received the newer and stouter PIN diodes, and the am

Mark, You may have already seen this link that discusses replacement of the Alpha 86's PIN T/R circuit with a pair of vacuum relays: http://volim63gtenet.mydomain.com/webservice3/old-mike/Mike/n3eaq_
Hi Paul, nice to hear from you. Yeah, I have followed that design modification philosophy about my amp, and used a lot of Alphas. Interesting that QSK was such an end-all goal back in the days befo

Bandpass filters, ferrite chokes at antenna feedpoints, stubs on power amp outputs to suppress even order harmonics. k9yc.com/7QP.pdf show a setup we use three times a year for FD, 7QP, and CQP ever

I think you guys are discussing something unrelated to my inquiry. 73 - Mark N5OT On 2/14/2020 8:14 AM, Jim Thomson wrote: <The biggest stations run (at least) two radios on each band, one "running"
