[Elecraft] New APF what happened?

[Hector Padron]

Well,well,well,lets put a couple of cents here.Last night at midnight when the XYL went to sleep and it was very quite I finally installed the Beta version 4.22 on my K3 and after few minutes when it ended up,move the dial to the lower end of 40M band and there was a station from Senegal,my dipole antenna is not too high,just 20 feet over the ground and his signal was only 559 and afer narrowing the DSP to 500Hz still heard him weak and little noisy BUT when I pressed for more than a second the XFIL/DUAL PB key to enable the APF WOW !! I almost fell off my chair,that Senegal station was so loud and clean as a local station,signal was still a S5 but the received audio was so clear and  loud that look like a 599 station.I am very impressed with this new filter and to be honest the last Icom radio I owned was the 756ProIII and that guy could never do this so well.
Again my claps go to Elecraft for having improved further more our K3's.
Thanks

John, did you check in the CONFIG menu to make sure APF is turned on?
