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 can set the gate with CONFIG:TX GATE using instructions in the owner's manual, on p59. 73, matt W6NIA K3 #24 On Sat, 01 Aug 2009 01:03:38 +0000, you wrote: >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.
