[Elecraft] K3 EQ settings?

[Clay Autery]

I did a lot of A-B testing on my K3s TX EQ settings, using Jim's base settings vs flat EQ, high base, flat mid/treb, et al. settings in various conditions on multiple bands.
Mostly for fun, because the science is well established...
Yes, I got more "you sound good, full, et al." with flat or boosted bass from stations that could copy on both settings...
BUT, I was able to demonstrate conclusively that more stations in "fringe" reception conditions copied when using full cut base, flat mid, and boosted highs.  I actually mapped it out.
Now I use a customized version of Jim's base rec that fits MY specific mic best.  (I don't need to boost the highs as much).
Win4K3 Suite allows me to store different settings based on purpose...

Not quite what I recommend.  My "starting point for typical ham mics 
like the Yamaha CM500 headset is:

Bands 1, 2, and 3:  Maximum cut (-18)
Band 4:  -6
Bands 5, 6: 0
Band 7: +6
Band 8 +6

Set Mic Gain and CMP for indicated Gain Reduction of 10 dB on peaks.

Then, get signal reports from trained listeners who have their IF 
bandwidth set for 2.7-2.8 kHz.  These are settings for maximum audio 
"punch" to get through QRM and noise. They get rid of un-needed bass 
which makes no contribution to speech intelligibility and boosts highs a 
bit because they DO contribute a lot. Ignore reports that tell you that 
you lack bass -- you don't want it, because it wastes TX power.

These settings increase the effective voice power by about 13 dB 
(multiplying power by 20).
