Have a Flex6600M wish I Could set a Tracking OFFSET TNF To have a Fixed Offset to the Main VFO frequency Can take out the Audio Pitch Hiss that is Annoying In receiver Audio This implementation would be easy for FlexRadio To do in the Menu of the TNF It like a razor edge notch in the Edge of the Filter passband If it only move as a Selectable Option as an Offset To the VFO frequency would be great Right now the TNF stays at a Fixed Frequency Having a Offset Option would be Great ! 73 Mike

    If you are in CW mode, you can get a similar effect by using APF (auto Peak Filter) which is automatically set to your CW pitch frequency. I also get reduced noise by using the RX EQ and setting the 500 Hz slider to the top and all the others to the bottom. Of course I use 500 Hz as my CW Pitch On SSB you can use the RX EQ to reduce out of passband audio hiss by dropping unneeded audio frequencies with the sliders (you can enhance a few, too. It really helps fix poorly EQ’d signals so you can understand them better.

    Ken Comparing 2.7khz with an offset TNF 100hz Wide at the edge gives better Audio that Merely setting Passband to slightly smaller Say 2.6khz The Audio Pitch shows up on wider BW Settings for SSB The NR and APF makes the Audio Harder to listen to due to rapid roll off In the high end audio frequency response Also found the EQ not as good as s Offset TNF Mike

    I'm with Mike. I also use this technique of placing the TNF on the edge. It would be pretty nifty to have the offset TNF as Mike suggests. One can only dream....
