[Elecraft] Gap Hearit Speaker

[Grant Youngman]

The GAP Hear-it is quite effective on SSB, but not on CW.  I don't use their speaker, but do have the Hear-it module.

Th narrower the bandpass, the less effective DSP noise reduction becomes.  For CW at narrow bandwidths, you might be better off using the audio passband filter (APF) in the K3.

Someone has recommended the Gap Hearit Speaker to me as being so wonderful. I have been checking into it, and it appears as just another DSP and speaker ckt. So, I’m wondering if it would really make any difference to me, with the K3 and it’s internal DSP.
