Barney, The most common cause for problems of that nature is RF feedback in the shack. If you have another receiver, listen to the transmitted audio while the K3 is connected to a dummy load. If there are no problems with that configuration, take a serious look at your antenna system for that troublesome band.
There is nothing in the K3 modulation scheme that is band dependent - in other words, if it works OK on one band, it should work well on all bands unless something external to the K3 is causing a problem. 73, Don W3FPR On 11/12/2011 7:34 PM, cbscholl wrote: > I believe that I am hearing raspy or slightly distorted audio on receive on > my K3.
