I put your tirade on the end of this as it's not relevant to the

The original post (by A*s*i*m*o*v) mentioned back to back diodes as
protection, so my reply was quite relevant.
Not sure what ruffled your feathers so badly Allison. But, whatever it
was, I am sorry if I did something that didn't meet with your
approval.
I also worked professionally as an avionics tech, and was in the
business when the first Motorola commercial repeaters using
synthesizers were put up...and they wondered why the other repeaters
on the same tower couldn't hear well. That only took 'em about 10
years to figure out. Then, about 10 years after that, they started
using gasfets, and it took them another 10 years to figure out they
didn't do well in high rf fields. By then, it was the 1980's.....but
at least they got it right eventually.
Maybe you designed some of those early nightmarish radios yourself?
Anyway, I wish you luck. And hope you realize the importance of
keeping the front end clean, which sometimes means dumping the gasfet
and using a bipolar preamp instead.
Actually, I hope the original poster (A*s*i*m*o*v) got the message
about introducing gross non linear back to back diodes across the
antenna terminals.
Have fun.
