But disregard the 2012 firmware update link and use the current one from
the Elecraft website (MCU 5.67 / DSP 2.88 / FPF 1.26, 1-22-2019) at

Hello,
I am a happy owner of K3. I came across another K3 with an early serial
number below 1000 in good condition at a local hamfest. It works well,
somehow better than my current K3, so my first reaction was, Wow. It seems
to have a lower noise floor and sounds slightly better.
My question is, how can it be? I have yet to compare all the settings for
either radio. The filter in my current K3 is 2.7kHz, and the new (new to
me) K3 has 2.8kHz. I am not 100% sure these filters can make that much
difference. Besides that, all hardware configurations are pretty much the
same. They both have updated KSYN3A modules. This K3 with a lower serial
number has KAT3, and my current K3 doesn't because I have KAT500.
Any suggestions?
Many thanks,
Chris KM1B
