[Elecraft] K3: Firmware 3.03 introducing artifacts?

[James Sarte]

Hello group,

 

I upgraded to 3.03 the other night, and immediately noticed several
fast-tuning birdies in places where I'm 95% sure were not there prior to the
update.  Switching antenna jacks or removing the antennas all together makes
no difference.  These birdies are only noticeable on the main receiver and
are not present on the sub.

 

Also, while the birdie removal function works, it doesn't seem to do it as
described in the release notes.

 

For example, the release notes state that the tool moves the artifact out of
the passband within 100 Hz segment.  But, I've noticed that if I have a
two-tone birdie occurring at 28.135.30 and the other at 28.135.35, using the
tool to remove the signal at 28.135.30 doesn't remove the tone at 28.135.35.

 

Am I missing something here?

 

73,
