Believe oit or not I found my instructions for installing the PT-11 tuner in
the pegasus. The instrucitons talk about the RT-11 circuit board. I don't
remember if there really was an RT-11. It may just be the circiut board
number for the PT-11.
Anyway, the green wire is the serial port control wire and it is the wire
that recieves command to the tuner from the serial port. So it need to go
to the receive data line of the serial port. The green wire needs to be
soldered to pin 3 of the DB9 serial port connector.

Subject: [TenTec] Pegasus Auto Tuner
I picked a Pegasus with an auto tuner and have been playing with it for
the last few days. I enabled the tuner and was expecting some relay
chatter and didn't get any. Now that I have a basic understanding of
how to maneuver around the settings I decided to investigate a little
more. I took off the cover and found a lose wire.
The radio has an LDG RT-11 auto tuner board rather than the PT-11 that I
seem to find referenced on Google. The tuner board has a set of header
pins similar to a normal Ten-Tec connector that is labeled J3. It has a
red wire from the radio guts soldered to pin 1 of this header instead of
a connector and the red wire appears to be the +13.8V line. There is a
green wire that was obviously soldered somewhere in the past, but is now
hanging loose. The only other wires are coax in/out lines.
My guess is that this is not an "authorized installation", but probably
is effectively the same as a PT-11 install without the proper
connectors. I can't find a schematic on line for the LDG unit, nor the
Pegasus for that matter.
Any ideas where the green wire goes?
Thanks and 73
