[Elecraft] New Elecraft Antenna AX4

[Rick Tavan]

+1 on that! I've tried the NR functions on various radios and never
actually used them - too much ringing, too little S/N improvement, a sound
too weird to tolerate. The SSNR in the recent K4 Beta makes Q3 signals Q5
and pulls nearly inaudible signals out of the mud to be readily copyable.
It reduces background noise dramatically, almost to "code oscillator
clarity" on CW and "full quieting" on SSB, greatly reducing listening
fatigue. I'll be using it a lot.

73,
