[Elecraft] K3:New APF what happened?

[N2TK, Tony]

John,
Maybe the impact of the APF is a moving target influenced by the band
conditions at the time?
Yesterday morning 160M was very quiet. I could not hear the VK6 without the
APF. When I turned on the APF the VK6 popped out of the band noise and was
easily copyable. There was no hint of ringing even with the bandwidth down
to 50HZ.

Last night as usual in the evenings here 160M was noisy. When I turned on
the APF it still did its magic. But there was almost a trace of "ringing".

I need to play more with it to see if it is a definite pattern comparing
between quiet and noisy band conditions.

Also I think I should install 4.14 in my second K3 to compare the two
versions to see if I hear the difference you are hearing

Hi

I was so impressed by the original K3 APF firmware. Why is it so lack luster
in the current beta?

I have read all the posts that there is no difference,  my ears tell me
different? 

When I used the APF in its original release on 160m and 80 meters it just
blew me  away to mars and back. Now I might as well not have it on! The
signals dont "pop"out of the noise like they use too. 

I might have to have my ears cleaned and checked for wax or something.
I am mystified especially when Lyle says that there is no difference in the
firmware.


The K3's APF in the current beta behaves much like the one in my Icom radios
and they are very ineffective in the Icom radios. 

I have shifted back to the old beta 4 times  and the results are better for
the old APF and it wins hands down. I will keep the old beta just for
contests, its just too good  not to use.
