I'm not sure what you mean by a "whurm noise". I presume it's some Scottish term. :)
If you have the audio monitor enabled then the K3 will play the digital audio from the computer sound card through its speaker. Depending on the pitch selected with the waterfall I suppose it might sound like "whurm". If the sound definitely isn't PSK31 at whatever pitch you selected then perhaps you are getting RF feedback into the audio. What you can do is long-press the TX button to put the K3 into Test mode. You can then TX and it will go through the motions but not actually produce any RF. If you still hear the noise then it is audio-related, if you don't then it is RF-related.
