One thing I have recently discovered is that my SX28A is not built to
the same schematic as the military model.  Specifically the two triode
sections of the 6SC7 tube in the audio section are interchanged.  I've
found two different versions of the schematic, one in the military
manual and one that agrees with the way my receiver is wired.
