Hello, Mike,
I had a little experience with some military L-band RF design (JTIDS), but
that is about all. I have also designed miniature lumped-element filters
for the 3 GHz region. But most of my work and also my ham radio experience
have been at HF. Also, I am mostly, but not entirely, an analog specialist,
which has put me somewhat into the Jurassic Age.

There is no reason to apologize for being good with analog. ;-) I
worked as a broadcast engineer during the time they announced the first
memory chip, (1101) which was a slow, noisy 256 bit * 1 DRAM with very
critical timing. I also did analog and digital work on the microwave
equipment built at Microdyne, before L3-Com closed the Ocala plant.
The reason I asked about the microwave equipment, I would like to
meet the people who designed the C-band CATV receivers I had to maintain
in the '80s. I always loved Collins equipment, till I ran into those
radios. They had a horrible failure rate, and took over six months to
have serviced by Collins. I think I still have a set of manuals for
the fixed tuned, and the agile models. I started repairing them for
United Video in 1982, and could return most of them to service the same
day.
