[Elecraft] Noisy K-3 Receiver

[K2MK]

I would like to hear more about the AF Filter Module. I didn't have any 
initial interest in the DSP board upgrade but maybe I would reconsider if I 
knew what the AF Filter Module did. Maybe someone who has upgraded could 
comment.

My understanding is that this is part of the DSP board swap upgrade,
and is in currently shipping K3s.

But I've been known to be wrong!
