[Milsurplus] [spam?] LO DFing, the myth that never dies!

[jmfranke]

The RBA was a TRF, but not a regenerative receiver - hence the BFO switch on 
the front panel and the lack of a regeneration control.  It is a great 
receiver.  I used one for years back in the 60's and wish I could find 
another.
