Wayne Knowles, ZL2BKC silent key

 Wayne Knowles ZL2BKC, creator of the ZL PLL boards for microwave and weak signal enthusiasts, became silent key on 30th December, 2022.

PLL boards, Signal Sources etc.

I also bought some cheap PLL Developer boards  to play around with. They suffer from jitter, but  good enough for experimenting with. Also picked up a 4GHz white RF noise source for testing microwave receivers, ie. 1.2GHz, 2.4GHz and 3.4GHz transverters.
