[Elecraft] K2 RF board resistance check - RYCOM

[Don Wilhelm]

Thomas,
Well, we located it there - but that is not the question.  The real question
is 'how does DC voltage get to RYCOM?'  It seems that the only path is
through another relay coil or through capacitors.  Perhaps the pulse through
the caps is enough to set or reset the relays, but I just don't know.

| Look at Sheet 3 of the RF Board schematic.  Beneath the I/O Controller,
