[TenTec] Omni D Problem

[Joseph Pursley]

You'd better check the bias setting of that rig. If that dosnt work check the
finals. I had the same problem with a Paragon. It suddenly started the the same
thing. The problem was that Ten tec, in constructing the radio forgot to solder
the Bias pot and it was making a mechanical connection until the heat caused it to
open up . The resultant instantaneous  current draw caused the power supply to
shut down.    Good luck    Joe   AKA kf5mc
