 Paul, et al,
If you do determine that it's a bad relay, here's a write-up I made for myself 
that will speed up the repair. By the way, don't try to figure out which one of 
the pair is bad. Just change 'em both.


Ten Tec swaps them all out when they have a bad one. I can't see benefit to 
doing that cuz who's to say how long the "new" ones have been sitting on a 
shelf somewhere.


I only swap out the pair for the failing band(s) and most of my relays are 
still the 18-year originals. 
Some of the replacements have had to be replaced again.


Removal of the Omni VI Plus Low-PassFilter Board
 
1)Remove the top and bottom covers.
 
2)Remove the bottom “inner cover.”
 
3)Remove the top “inner cover.” (It’s along the back of the unit and includes 
thespeaker plate)
 
4)Unplug J13 and J17, and remove the 3 screws at top the edge of the board.
 
5)Turn the unit over and unplug J8 and J14, and remove the 3 screws at the 
bottomedge of the
    board.
 
6)Cut the ty-wrap holding the J14 harness and the J17 coax. Also remove 
thenearby double-
    sided tape.
 
7)With the rig still upside down, remove the board far enough to unplug J12 
andthen 
    J7, J9, and J11.
 
Note:To work on the board (i.e. Replace relays, etc.) the white coaxes can be 
leftin place.

I’d check the output filters. The relays have a tendency to go kaput. If you 
can  
monitor DC input current, that would be helpful. If you’re drawing 15 amps and  
getting 10 out, then output filters would be a good place to start. 
 
You didn’t mention if it was on one band or all bands. 
 
Try using the separate antenna input to see if your receiver comes back. That  
jack bypass the filter board and swr/alc board.

&gt;&gt; A couple of days ago while in QSO my Omni VI+ lost both rcv and TX. 
&gt;&gt;  
&gt;&gt; Into a dummy load it shows about 5 watts reflected with about 10 watts 
&gt;&gt; drive. I tried this with 2 different dummy loads and 2 different 
&gt;&gt; meters, plus on the meter on the radio in the SWR position all same 
&gt;&gt; results. 
&gt;&gt;  
&gt;&gt; Until this happened, it had worked flawlesly for years. 
&gt;&gt;  
&gt;&gt; It is like a short across the output/input. Has this happened to 
&gt;&gt; anyone on here? Or have an idea what the problem could be? 
&gt;&gt;  
&gt;&gt; At $110 per I am not anxious to donate to the TT relief fund if I can 
&gt;&gt; fix it myself. 
&gt;&gt;
