[MRCA] Looking for and automatic antenna switch for the BC-639/BC-640

[mkdorney at aol.com]

Hello Everybody,

         I'm looking doe an automatic antenna switch to switch the antenna used by the BC-639 and BC-640 transmitter and receiver working together on the same antenna.  This is an old Control tower radio that I'm trying to convince an air museum to restore to working condition.  Any help is appreciated.
