[Elecraft] New to Elecraft - help with audio settings

[Walter Underwood]

The ModMic is an electret mic that can be added to your favorite headphones. I’ve been suggesting it to people for years, and I’m delighted to hear that someone is using it.

Electret mics are pretty flat, so just go with Jim Brown’s recommendations. You can see a graph comparing his recommended contour to Heil’s at my blog post (link below). I plotted all the contours posted to the Elecraft mailing list to compare them. About half were very similar to K9YC’s contour, and the rest were all over the place.

The description of this mic is in conflict with itself -- it first calls it a "noise cancelling mic" but down the page calls "uni-directional."  VERY different -- noise cancelling works on the basis of distance -- two perfectly matched capsules, out of polarity, reject sound that isn't within an inch or so of the mic. In general, they sound awful. Unidirectional mics are ok but not great -- they suffer from proximity effect, which strongly boosts low frequency sounds, wind, breath pop,  and vibration (like handling noise).
