I didn't know Polycom made one, Pete but it sounds liek a neat mate for 
your HA-410.  This Johnson came from a local guy who ran an aerial 
spraying business, using the old AM business band located just above 10 
meters.  He gave me several of the solid state mobiles too, just wanted 
it gone.  Turns out he was trying to copy some information in-flight and 
the skip was in and he ended up spraying the wrong field.   Ripped it 
out and went FM.  I don't know how widely this AM business band was 
used, but you do see amps from various CB makers like Sonar on eBay and 
at hamfests.  What I thought was cool about the Johnson PA/85 is the 
high level modulator vs.  a linear amp.
