It was my impression, based on two sources, that for PSK31, it was
best to use the 400Hz filter (FL2 in my case), not the 2.8kHz (FL1 in
my case) filter. Was I wrong? 

But to check, I went to change to the 2.8 KHz filter for the data
mode, and so while in data mode, went to the config menu. and changed
FL2: ON to NO, with the aim of then setting FL1 ON to YES. However,
the configuration menu does not have FL1, so wasn't able to test
whether my problem is that I should be using the 2.8 kHz filter.

No, but I assumed that the installation utility might be designed for
the operating system, and its development for Linux was slower than
for Windows. 

When I run the k3util utility and click Copy New Files from Elecraft
Server, the new files are downloaded to the ~/Elecraft/K3_Firmware
directory. However, the downloaded files are the MCU 2.46 that came
with my K3, not the newest firmware, MCU 2.57.

Any Linux users out there who can explain?
