[Premium-Rx] consumer vs premium-rx's

[Carcia, Francis A HS]

Every job I've worked on for the past 8 years or so required a last time buy
for production. The COTs components change constantly and thermal
performance is always 
a big question that requires a lot of testing. You no sooner qualify a
system and parts go obsolete. 38510 / 883 parts were great and I love a
radio with that type of normal components. my $.02. fc

An example of component quality:  the PRC-74 was a small 20 watt
solid-state military SSB/CW transceiver from the 60's.  When I was in
Navy MARS, we picked up some through the equipment disbursement program.
The units had been stored in an open crate in a field outside of Austin,
TX for at least 4 years, exposed to rain, heat, cold, etc. THEY WORKED! We
found a sheet with one of them that listed the cost to the government as
$6800.

Sounds like a lot, but consider that every solid state component had been
subjected to repeated hot/cold cycling and vibration testing before it
ever made it into the rig (one can only imagine how many didn't make it),
and every connector and PCB land in the unit was gold plated.

When you removed one of these units from it's case, you got the same sense
of awe that we get today when we look into a premium receiver.

Just my opinion - maybe I'm more easily impressed than some! :-)
