[R-390] R-1247 Nasa Receiver FOR SALE

[Glenn Little WB4UIV]

Do you have the Manson Labs synthesizer that makes this receiver 
different, or just the receiver with the extra BNC connectors and 
relays to allow it to operate with the synthesizer?

I think that the receiver will still function as a standard R-390A 
without the synthesizer, possibly requiring some jumpers.
