[Elecraft] Filter question

[Don Rasmussen]

>> I'm a little confused as to what the KBPF3 is
really providing.

Bill - the stock K3 band pass filters will greatly
attenuate signals that are more than 1 megacycle from
a ham band. The KBPF3 will resolve that problem. 

Still, the only roofing filter that comes with the
stock K3 is the 2.7 khz filter so that's what you
would be hearing through in the stock setup.

So you would need the AM 5.0 filter for better
fidelity. 

Ultimately, the 15 khz FM filter would be the best
choice for roofing AM and FM (on receive).
