[MRCA] World War Two ATC tower radio

[mkdorney at aol.com]

I'm trying to help out a museum purchase and restore a World War Two Control Tower radio.  We've whittled things down to a BC-639/BC-640 radio combination.  The objective is get a complete and functioning radio. We have the transmitter  ( BC-640 ) complete, in the rack ( Frame FM-39 ) and the Power Supply ( Rectifier RA-42 ).  We also have a receiver ( BC-639 ), but no frame FM-39, and no power supply RA-42 for it .  Modified equipment is not an option, since this is going into a museum.  We will also need an antenna switch external to the radios so that the radios will work as a transceiver.  There is a Junction Block, JB-45 that is an antenna switch, but we don't know if that antenna switch will work with the BC-639/ BC-640.  The BC-639/ BC-640 operate on 100 to 156 MHz AM.  At least part of that frequency range falls into the 2 meter Ham radio band.  Any help would certainly be appreciated.
