These two sentences contain all of the phonemes (sounds) of the English language and I have found them useful in adjusting things: "Joe took father's shoe bench out." "She was waiting at my lawn." Al W6LX >> The process is to speak random words for several seconds while monitoring >>

A K3/P3 can be used to measure the KX3 SSB TX bandpass. The process is to speak random words for several seconds while monitoring with a P3 in "Peak" mode. After about 30 seconds the display will stabilize. The K3 filter width is 2.1 KHz 350 - 2450 Here are some measurements:

As you may know, the 664 and 666 were EV's first "variable-D" mics -- the 666 was the pro version, the 664 for "PA." The 666 was known as the Buchannon Hammer because Lou Burroughs, co-founder of EV with Al Kahn, demonstrated their ruggedness by using one to drive a nail. (EV was in Buchannon,

Since I am in the field I can't check, but at some past point, I put a file in the folder with suggested EQ settings they've been used by many including WG0AT and found them very useful. Paul KB9AVO On Nov 10, 2016 4:14 AM, "Richard Lamont" wrote: > On 09/11/16 21:28,

Best is to eliminate the low (50, 100, 200 Hzbands). These contribute nothing to intelligibility, and the MH3 has frequency response below 400 Hz, so you'd just be wasting energy because of this. With the low bands at 0dB, I got reports of muddy audio. I would also suggest a mid-band boost,

Pretty much the same for all modern mics. Some have an upper midrange boost, so you’ll need to decide whether you like that. Here is a writeup on TX EQ, compression, etc. https://observer.wunderwood.org/2015/09/09/transmit-audio-and-compression-with-the-elecraft-kx3/
