Hans!
I am 20+ years your senior. It should be me grumbling with skepticism
about your simulations and not vice versa!
:-)
Smiling anyway, JZ

Hi Willie
And, of course, the third question is if adding the commutating diode and/or the zemers will affect the output characteristics (spectral purity, spurs, harmonics), in such a way as to render transceiver illegal to operate.
Yes, spot on. That, and whether the diode and/or zeners add anything to the receive noise floor. Probably not. But I need to measure, simulation isn't good enough for me :-D
I tried to order some 47V zeners but got BZY47. Which is 9.1V. Sent back, and got BZY47 **again**. I should put in a large Digikey order in the next couple of weeks and will add some to it. Here Digikey orders take 10 days and incur a significant expense so you can't do it for a sub $1 order like you can in US.
