Once the rig is stable, if I'm left with a heterodyne in the pass band it
can be tuned out with PBT control. I don't mean "filtered out" with PBT;
just a few degrees rotation of the PBT control around its mid position and
the heterodyne rapidly moves in audio tone and out of the passband. If the
PBT control is more than about 5 degrees away from its central position I
never hear a heterodyne at all. I guess this must be some funny mixing
product involving the15.3 MHz PBT oscillator.
The heterodynes are clearly audible above background noise, but they don't
move the S meter and now I know how to shift them I can probably live with
them.
Steve,
I've had this same situation since having my Omni 6 back from the factory
upgrade to option 3. Don't remember it being present before the upgrade. I
just always move the PBT and don't worry about it.
Think I'll dig around in there this week and see if I can find any clues. At
least you know you're not the only one !
