[Elecraft] Dynamic Mics on K3

Jim's settings look good for standard bandwidth SSB.  For the K3's ESSB 
mode, I would rein-in on the EQ extremes, and try a cut at 200Hz.  The 
50-100Hz bands can be flat or even boosted slightly, depending on the 
response of the mic.  At the high end, I would back off on the 3.2K setting 
to no more than +5-6 dB, again depending on the mic's response.  Results 
will vary, but that's a good place to start with a dynamic mic.

I'm not sure if anyone has measured the K3's TX ESSB distortion products 
between 50-100 Hz (sourced through the front panel mic connector), but 
backing off on TX output power and running a slightly elevated V+ may be the 
neighborly thing to do.
