[Elecraft] MP3 Demo of the K3's Noise Blanker under some rather severe conditions

[Robert Tellefsen]

Wow!
I was trying to work the CQ 160 SSB tonight, and the noise level
was such that it just wasn't worth my time to sit there trying to
figure out what I was hearing.

Now desparately looking forward to my K3 (in April?).
73, Bob N6WG
