[GreenKeys] Alternate Dovetron Adaptor

[Jack]

If anyone has some old TTY polar relays kicking around
(which seem to be good) you can wire the two coils in
series, place a 100 OHM resistor in series with them and run them
right off the MIL188 output of the Dovetron. You will need
to determine which side of the relay's SPDT contacts
give you a MARK, and away you go!

Remember, the relays have to be in good shape and
must be adjusted correctly.
