I acquired an EF Johnson 5318 which is a very old radio in that when it powers up it only displays 1 version number (3.x.x something) and can only be programmed with PC Configure 1.28.08 using 9600 baud.? The file version on it is 5.5, I believe.? I am using a remote head, not a HHC.
Is there an older method or version of PC Tune than version 2.2.3 that will work on this radio?
Otherwise, the radio works fine in that it transmits and receives in analog and P25.??
