[Elecraft] K3 APF FINE Tuning

[Ron D'Eau Claire]

I'm not clear on the value of changing the APF center frequency
independently of the actual signal center frequency. If the other station
drifts off-frequency, I just tune him back in with the RIT or, since I use
SPLIT as my basic operating mode, with the VFO knob. 

In what circumstances if tuning the APF frequency useful?

Yes, you can fine-tune (1 Hz) using either the VFO or RIT.

In addition, it looks like the next release may provide 5-Hz  
increments for tuning the APF center frequency (presently 10). We're  
testing that now.
