Can you hear the Omni TX on the dummy load using the 706 in RX (no antenna)?
Or put the OMNI TX on the antenna and 706 RX on a dummy load.. Can you hear
the OMNI VI?

So far, it appears to be ok with WWV although USB and LSB are a few clicks
different.
RIT/XIT both off, Split off, VFO on A, side tone set for 700 hz.
I set the Omni to CW on 14.050.00 on a dummy load. I set the 706 with no
antenna at all on 14.050.000. Bring up power to a few watts on the Omni.
As I change the sidetone, but not the frequency in either radio, the signal
in the 706 does not change, indicating to me that the transmit frequency
isn't changing either, merely the sidetone. I thought the sidetone
indicated the transmitter offset, which would vary exactly with the
sidetone,
Varying the sidetone throughout its range doesn't vary the received signal.
I hooked up the antenna, and tuned in AD4ES, good strong signal on 14,032,
matched his tone to the sidetone at 700 hz, pushed the power to 100 watts,
and after his CQ sequence, gave him a call. Nothing! 4 or 5 times, I
repeated this. He stopped each time and began calling CQ again by the time
I sent my call. XIT/RIT off, PBT at 12 noon, VFO on A, Split off.
I should be able to be heard at the station with a strong signal here.
Something is goofed up.

Be sure XIT is not on nor is RIT on. It seems that the radio might not be
receiving or transmitting on the same frequency. Also be sure you aren't
in SPLIT mode.

Subject: [TenTec] Omni VI mystery
I have an Omni VI with Opt 3 installed, purchased from an SK estate about
a
year ago. After our move to Texas, I got an antenna up and got on the
air. The meter and a couple of other functions were inop so off it went
to
TenTec. They fixed all this, gave it a good checkout and got it back to
me
very promptly.
I have the output going to a wattmeter, thence on to the AH-4 remote
tuner
which feeds the 130' dipole with twin lead. On CW, the transmitter loads
to 100 watts output, good SWRs etc.
I have noticed an inability to get replies on CW. I spent an hour the
other night calling W1AW/5 in Missouri, another hour or so each this week
calling W1AW/1 and /2, and various other stations. Some of this I
attribute to being a 100 watt station with a wire antenna in a pile up.
There have been other instances where I have called and called only to
have
the other station start up a CQ again.
Yesterday I decided to fire up my Icom 706 at QRP levels and work the
Florida QSO Party on 20M. To my astonishment, I had no trouble making
contacts with every station I heard, running 5 watts, other than being
treated as a weak signal (AGN?) which I'm sure was true. While doing
this,
I heard HB9CA in the Helvetia contest, gave him a call and after going
QRO,
made contact. I also worked W1AW/1 with 5 watts in 1 or 2 calls. I made
25 or so contacts in Florida with the 706, all QRP.
This started to puzzle me, so I shut down the 706 and fired up the Omni
VI. Once again, I had trouble getting responses. I tried fiddling with
the sidetone, thinking maybe I was not tuning to be inside the other
station's passband, but did not improve things. The "split" switch was
off!
I am stumped to imagine why I can make contacts at 5 watts with the 706
but
not on the Omni VI at 100 watts, same antenna. The radio appears to be
operating normally in every respect. Is there something I am overlooking
in the set up of the Omni VI? Any other possibilities?
TIA
