Wayne, Congrats on what looks like a very well-designed amp. I've been waiting on an amp with these features for a very long time. Of particular interest to me is your continued use of PIN diode T/R switching. Can you describe SWR protection to the Rx PIN diodes at the 1.5KW level? I suspect that a fast-detecting SWR switch will be the main focus of protection, as well as HV back-biasing of the Rx diodes. An open or short RF termination requires over 900V DC to keep Rx PIN diodes from going into conduction. Can you describe this area of circuit protection just a bit?
Secondly, I know that fan noise is difficult to quantify in words. Anything particularly innovative you're going to minimize cooling noise? Thanks!
