[Milsurplus] Convoy radios and the MBF

[WA5CAB at cs.com]

The 115 VAC/VDC power supply for the TBY was built to allow usage of the 
TBY on merchant shipping equipped only with MF and HF CW rigs.  Much of the 
pre-war merchant shipping had 115 VDC systems.  It could talk to the TBS on 
the escorts.  The little MBF was built to replace it.
