[Premium-Rx] Beacon Hunting

[Cecil Acuff]

I just sold an R-75 with the full Kiwa mods.  I believe the R-75 to be the 
best general coverage receiver out there for under $2K...maybe $3k.  It held 
it's own with the R8B and many others for around $600.00 with the Kiwa mods 
all new.

Of course it's been discontinued....

I've seen them used for $350.

I used mine quite a bit for NDB hunting!  Worked great.
