The "noisy DSP" phenomena is well known. Rob Sherwood has also

I wonder if he is talking about QRN from storms, etc. or manmade QRN?
I've heard this before. The K3's AGC pulse rejection feature is intended to
improve
performance in this area.
Has anyone tried to quantify or describe this better? It would need to be done
with an a/b

Thank you for posting K9OM's comment.
FWIW I have a Perseus and two other receivers which both use H-Mode mixers,
one of which uses a version of PA3AKE's H-Mode front end.
With the Perseus used as a stand alone receiver, I have not experienced this

Thanks for your explanation, I had missed the point of RLVZ's comment.
A related cause and I am speculating here without doing the calculations,
when the noise is rough and signals are at or under the noise floor might be
the added in-passband low level intermodulation products generated by a

Would it be possible to add a function to the utility which creates a
file which lists all the K3 settings and configurations and control
settings when it is invoked? Something that could be cut and pasted
into an email or attached? This would be useful for many problem
resolve sessions.
I'm thi
This is a huge undertaking, and the MCU config variables are a moving target.
But it is (low) on my list of possible K3 Utility enhancements.

Regarding key clicks. I suspect this may vary considerably with the
specific circumstances including the likelihood of considerable
variations in the individual transmitter rise and fall times and and the
roofing filter bandwidths.
Last November, I think, I read a suggestion about blanking key
eration on this.
