Was the Omni VI drawing lots of current from the power supply when you
keyed it on 160?

I intend to run the Omni VI+ on a dummy load today, on every band, but I
saw nothing that made me think the match was a problem. I can imagine
seeing a bad load would "fold back" power but there was nothing to fold.
The 706 matched up just fine, same antenna, same feed line, same tuner,
same connector, etc.
I'll report back if anything develops.

Make sure the Omni VI is working OK on the dummy load.
I'm surprised the AH-4 even found a match.
It is only rated to cover 80 thru 10m.
I used an AH-4 a lot in the past but I could never get it to load anything
up on 160m.

Subject: [TenTec] 160 Meter Problem
I was sitting in the shack minding my own business last night when I
noticed
on the DX cluster that W1AW/5 was on 1821.5 in Oklahoma. I have not tried
160M here, but do have a 130' dipole and an AH-4 to match it with, which
might work, so I thought, "what the hey?"
I got it all set up and could hear W1AW/5 extraordinarily well. I moved up
the band a bit to tune and ........ nothing. No output whatsoever. I
checked... traced the coax, antenna connected to wattmeter, wattmeter
connected to Omni VI+, AH-4 tune control getting power, etc. All seemed to
be in order. I tried again... nothing. The radio went into tune no output
no tone, nothing. I switched to 80M, found a clear spot, tuned normally.
I went back to 160M, nothing. I advanced the power knob from nothing to as
high as I dared... still nothing.
I then moved to the 706MKIIG, got it going on 160 and made the contact, no
problem, although I did have to use 100 watts instead of 5.
This is the first time I have tried this Omni VI+ on 160M, but it seems to
be working just fine on the other bands, very well, actually.
What could this be? Where should I start?
