[Elecraft] MCU 3.30 DSP 2.26 and Loud Noises

[David M. Elliott]

Lyle,

Most of us understand that we are beta testers and what our  
responsibilities in that role are.

We appreciate what you are doing and I will repeat again that the new  
NR function is awesome -- better than anything else out there by a lot.

We are all anxious to help solve the noise problem.

In my case, the noise blast was preceded by a period of time (several  
minutes) when the volume control did not work.  I had it turned to  
minimum and could still hear the signals at normal volume.  When I  
tried to fix that by twiddling the volume control and/or adjusting the  
NR settings, the noise blast happened.

Thanks again for working on the holiday weekend.
