Good Lord!!

I'm setting here with a very weak carrier tuned in on 10m that is barely
detectable in the noise with my 250 CW filter set to 50hz.

When I turn the APF on it jumps out of the noise and actually sounds like an s-5
or s-6 signal!!!

What a wonderful addition for CW operators.

GOOD WORK!

Thanks,
