Carl,
Thanks for getting this back to at least the original topic!! I'll refrain
from posting any more questions, just call Ten Tec repair, as the questions
seldom get answered, just the threads distorted. I guess the answer to my
original question is, "no, there isn't a source of voltage from the Orion,
somewhere between 3 and 15VDC, on during transmit only, that one can use".
Gee, that would have been simple and not wasted so much time, hi.
73,
Don, WB5HAK
