Re: [Elecraft] K3 Crackling audio with Noise Gate running

Hi Lance, I had exactly the same reports from local stations when I tried to use the feature. (I'm using a Heil dynamic ProSet plugged into the back.) After playing with various adjustments and finding none that would elimminate the distortion, I elected to turn TX Gate off and not use it. Mak

Lance, If that is a standard Heil headset (with a dynamic mic element like the HC4 or HC5), then you should *not* have bias turned on. If you have the Proset K2 (with an electret mic element) or a Proset with an -iC (Icom) suffix, that also has an electret element and will require bias. The "

Try adjusting the noise gate level up until the crackle disappears. If you have it set too low, it doesn't seem to close quickly enough with high background noise levels. I had the same problem with a cooling fan behind me at an angle. Works fine now. The level here is 18. Of course, YMMV. You

Howdy! I am using the Heil headset with the K3, and have the mic connected into the rear panel (the front panel connection was having RF distortion) with the HIGH bias level. The Mic gain is less than 5 and the compression is 10. The ALC is never out of the indicated range. With the TX
