Arthur Dent-"The -12 VDC is used for the RS-232 so if that
was giving you the problem you wouldn't see anything on your
com port (note it will work at -7 VDC or so)......."
the -12 VDC is also used by the OCXO as tuning voltage! Bert Kehren
It may or may not be used for tuning voltage but what I said is
100% correct. The Andrew/Grayson units these T-Bolts were
used in provided -7 VDC for this negative supply and the same
T-Bolts work properly on -12 VDC. If this voltage is missing, the
com port will not work.
