[Elecraft] Noisy band changing

[Bill Scovell]

Hi Gang,
I'd like to share a problem I am experiencing with K2/1946 with latest
firmware revision.
I'm getting a brief but disconcerting burst of noise when changing
bands 'downwards' from 24MHz to 21MHz and from 18MHz to 14MHz. When
going from 24 to 21 the noise is like a burst of static, but from 18
to 14 the noise has a raw oscillatory character around 500Hz. In both
cases the duration of the noise is less than half a second.
This problem exists only when 21 and 14 are approached from the next
higher band --- changing 'upwards' is perfectly clean.
Some months back I had a problem when 21MHz was 'skipped' when
attempting to change to that band from either direction, and also it
could not be selected by 'direct entry'.
Wayne advised a 'full reset' (4,5 & 6 held down on 'power up') and
this was successful.
For the record I've just tried another 'full reset' but the current
problem remains.
Anyone else experienced this?
Any thoughts?
