Go to the Ten-Tec website and look in the link for the "knowledge base". They
explain which frequency you are actually TX'ing on in CW. That may have
something to do with it. Good luck.

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
