The original hamtronics repeater I put on the air
about 1980 ran the original 600KHz split. I replaced
the receiver with a Midland Low-Band Mobile (works
very well), which scans both the 500 & 600KHz inputs
as well as two other popular frequencies. (The repeater
inputs are priority scanned).
I favor the original 600KHz split because I couldn't
stand having the 500KHz split forced down my throat
even though it probably makes more sense. So both
inputs remain in the game plan for now...

Circa 1981 I built a tube type 15 watt amplifier to
use with the Hamtronics transmitter. It would pretty
much make the system hose up real bad so I took it
off (even after building much strip line filtering
from the ARRL Handbook. The original 2.3 whoping
watts system works fine... for higher power more
tx and rx protection would obviously be required.

Channel 2 from San Francisco is line of sight to our
system. A combination of antenna shielding, some
homebrew filters and a bit of dancing made the system
usable and a lot of fun before the higher power tx
was placed in service.
