[Milsurplus] possible modifications for RBC receiver?

[WA5CAB at cs.com]

In addition to that, if you modify an RBB or RBC by converting it to have a 
product detector, you will lose the ability to work break-in CW.  The two 
receivers were design for the Navy's standard practice for MF and HF sets up 
through the 1950's where transmitters usually had dedicated antennas but 
receivers were usually tied into a receiver antenna transfer patchboard.  And 
there were usually no control connections between receivers and transmitters. 
 Which meant that the receivers had to be able to work satisfactorily with 
a 500 watt transmitter connected to a nearby antenna being keyed.  For AM 
voice, other than the low power TCS, audio was muted in whichever remote was 
patched in.  The recovery time of an RBB or RBC on CW is instantaneous, so 
you can use it as a keying monitor and still hear someone trying to break you 
through your dits.
