Hi, On some signals the cw receive note is somewhat basy and fuzzy. PBT doesn't help. My question is will the 9 mnz 500 and 250 hz filters help with this condition? I already have the 500 and 250 mhz filters in the 6 mhz. if. What confuses me is that not all received signals display the condition. Thanks, Vince Santis, N1VS NEQRP #598 QRP-L #2372 Winsted, CT
