When I tap DISPLAY and get "S1 nr nt" I hear a raspy tone ticking off the
seconds. It is present in any DSP or time mode. It is loud enough to be
annoying. This phenomenon only occurs on 60 meters. Has anyone else experienced
this? Is it normal?
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 :-)
