Jim,

I'd check zero beat with WWV. Sound like you're off QRG a bit.

Let us know !

PS. Can you check against another rig?

Quoting Jim Allen <jim.allen@longhornband.net>:

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

73 de W6OGC  Jim Allen
