[ML-Hams] amplifier

[Bruce Campbell]

If it is the same Chinese 8w amp that I have it is water tight already.
Also BBHN is not spread so you aren't limited to the spread spectrum power
limits. I had a USB WiFi adapter plugged directly into the amp that was
plugged directly into the antenna. A raspberry Pi running HSMM-Pi OS drove
the adapter. One got ya with my amp is that my amp could not handle much
input power. Power over about 500mw saturated it. I ran it at about 100mw
to keep distortion down.

The amp was a pain. I would get it working without the amp first then add
it once I get happy with the set-up. If it is the same as mine, it looks
like a gold coloured metal box about 3" X 3" X 1" with 2 "wings" to allow
you to mount it. It also has 2 BNC connectors on it.
