Yes, this is normal.  The KDSP2 pretends to be a real time clock, and 
the K2 does not mute the receiver during auxbus transactions in real 
time clock mode.  So, on certain frequencies you will hear the 
once-per-second raspy tone.

The nice thing is that once the DSP is set up, you don't often need the 
menus.    The AFIL button provides 4 filters per mode.

And with firmware 2.04 you have front panel access to toggling the 
denoiser and notch filters without resorting to the menu :-)
