[Elecraft] K3 APF

[N2TK, Tony]

Finally had some time to play with the APF. This morning VK6HD was called
out on Topband. I could not hear him at all. I have limited real estate so
no long beverages. Just have some pennants and flags for receive. Tuned to
where the pileup was at. Turned on the APF and he pops right out of the
noise. Listened to him for about a ½ hour trying different settings – RF
Gain, Width, Preamp both internal and external. I forgot to try the NR. Just
amazed the one thing that made the difference comparing the other parameters
was the APF. 

I just need to remember to HOLD the XFIL button and not TAP it to toggle the
APF.

 

Tnx for the great implementation of the APF. Now if only there was a spare
switch? Maybe when Santa brings me a P3 I could toggle the APF from there?
