[Milsurplus] RBC

[George Babits]

Having owned a couple of RBB/RBC pairs over the years, I have to say they 
are great sets.  They do decent job on SSB once you get the hang of using 
the BFO andriding the RF gain.  I wish I still had  a pair, but all my room 
is now taken up with various HROs.  Every old receiver I have ever had that 
someone added a product detector was pretty well ruined by the addition.
