[TenTec] Before I call Ten Tec . . .

[Jim Goudie]

Thanks for the replies!

First of all, a big confession....  After getting up this morning, I looked at the rig, turned it on, and in my half-awake state I just played around with it, as if some easy fix would jump out at me.  I'm glad and sorry to say that one did.  Glad because all bands receive now... and sorry because it shows how dumb I can be!

I have another Omni VI which I was going to sell, until this one quit.  When I switched back to using that one, I moved all the filters over!!  Yup... my receive problem was that filters were selected that aren't installed in the rig!  Not much gets through that way!  How dumb can I be?!... receive problem solved.

So I'm back to my original problem with no power out... not so easy.  I'll report back after some more snooping around.

By the way, I had forgotten that they don't work on Omni VIs anymore...  Thanks for the reminder and motivation to keep looking...

> I have an Omni VI opt 3 with no power out.  I've taken it apart, poked around with my limited skills and VTVM.  Resistance checks on the power transistors seemed ok.  R5 on the DC Input board (.015 ohms) checks ok and the voltage is ok.  I've exercised the connectors and put Deoxit on them...  But the problem persists but my abilities to fix are limited.
