[TenTec] Omni D problem

[Gary L. Ingersoll]

When I go to cw with the mode switch on my Omni D, it keys up, even though I see no unexpected ground anywhere on the t/r line.  When I go to lock, where it SHOULD key up, nothing!  And of course, I can't key it, since its always on in cw position.  There is 13 volts on the "T" line at all times, receive and transmit.  Since the  "T"  line runs all over the place, I can't seem to find where its coming from.  Any Ideas?
