[AMRadio] FW: Homebrew receiver

[Brett Gazdzinski]

Jim,
I don't forget that all the commercial stuff was built with cost
and profit in mind, I can well understand the restrictions
they faced when designing and building it.

That is mostly why I did not keep the stuff around, it was
too much of a compromise.

Many people would not like my stuff as it tends to be quite large
for its power output.
My 300 watt push pull rig (globe king 400 copy?) is
three times the size of the globe king.
My mod transformer likely weighs more than the entire glob king!
Hardly the thing when you are tight on space, or have a bad back...

Collins was close, they made some big and heavy rigs.
I had a 30K1, and a KWS-1, both quite robust, as is the
32v series.
All those rigs were 100% reliable, and I still have two 32v3,s, which
continue to run like Swiss watches. 

None of that stuff was affordable by many when it was built!
