[Elecraft] New K3 owner, couple of questions (APF vs. DUAL PB, NR under the water sound, KPA3 temp)

[Andreas Hofmann]

Hi,

I put together my new K3 without any issues. My 8 and 10 year old daughters helped and they really enjoyed it too. Overall I am very happy with its performance.  I do not seem to need PRE on the high bands as much, but I do seem to need ATT on the low bands more...  I guess that is by design. I have a few things I need to figure out and the manual does not seem to help:


1.       DUAL PB, APF. I am not sure I get the APF to work. I do not hear or see the middle peak of the filter. I think I only get DUAL PB, no matter what I set in the config menu.  I am using the latest FW. Any ideas how to verify?

2.       NR:  I like how the noise goes away, but I do not like the under-the-water sound (K2 owner, no DSP experience).  I seem to switch constantly back and forth... I am using the default setting for NR (F1-1). Is there a way to back off the setting slightly to have a better compromise setting?

3.       KPA3 temp: The fans are MUCH quieter as my K2's which is good, but I do worry that I have not setup something right...When I monitor the KPA3 temperature, what is the max value that I should watch out for? I am getting up to 41 C during casual operation.

Thanks in advance and 73,
Andy
