<div class="moz-cite-prefix">100% Linux in my shack ... am not into
contesting, so the list below meets my needs. Here's what i use:<br>
- Logging: cqrlog (built from src)<br>
- FT8: wsjtx (built from src)<br>
- PSK: fldigi (built from src)<br>
- LOTW: trustedqsl (installed the .deb from arrl)<br>
- SDR: gqrx and cubicsdr (built from src). Planning to test

These run on a homebrew intel box with debian bullseye.<br>

There are several.

I'll have to admit that though I used to run Linux in the shack,
nowadays I'm heavily into contesting, and I'm running Windows,
as N1MM+ covers a lot more contests, out-of-the-box, than any
Linux contest loggers I know of.
<br>
<br>
Back when I was running Linux in the shack, I was using Xlog for
daily logging, and tlf or yfktest for contest logging. I was
also a maintainer for the Alinco DX-77T section of Hamlib
(Hamlib is a library for controlling radios, rotators, and other
ham computer-controllable hardware. Most Linux apps that need
to interface with radios use it.

<br>
I'm using an Astron analog power supply, so I don't have much
problems with RFI from the power supply. I've mostly had to
deal with RFI the other way, with RF in the shack affecting
devices connected between the PC and the radio. That's been
dealt with by the selective application of cables with ferrite
beads build in, or by the user of snap-on ferrites.

<br>
Some of that may be coming from cables from the computer, which
might be handled by snap-on or wrap-around ferrite chokes
(Palomar Engineers has a nice kit). Some of my issues were
helped by tying my radio and computer hardware to a common
ground bus. Also check the cables on the monitor.

I've got loads of both linear and switching power supplies in and
around the desk but I spent lots of time putting chokes on
everything to keep it clean. I also usually spend a bit more on
the supplies. Most of my switchers are DIN-rail mount units or
similar industrial units that have filters in them and don't
radiate much because they're intended to be in close proximity to
other sensitive devices like PLCs. Nearly everything at my desk
that used to have a 5V wall wart is now sharing one of three
5V/10A DIN rail units. I have an enclosure at the end of the desk
with a single C14 inlet with integrated magnetic filter (like this

and terminal blocks that I use to wire appropriate patch cords to
power the devices. I did the same for a couple higher voltage
items (mainly 24V devices) and anything that was network related
now runs PoE. I used to have over 40 wall warts and I'm now down
to two because they're oddball voltages (one is 7.5, the other is
15).
<br>
<br>
I also usually put in ground breaks on all the audio lines between
the radios and computers. Most of my radios are patched through a
couple Behringer mixers so I can route audio to different places
(headphones, computers, speakers, etc.) but I find that a good
portion of audio problems almost always stems from ground loops.
I buy the ground isolators intended for automotive applications
and patch them inline with the radios. The good ones are
transformer units so you get galvanic isolation on the audio lines
as well as the ground break.
<br>
<br>
I've got three VHF/UHF stations and one HF station and no issues
from my operating area. Nearly all my noise is from the
neighborhood coming into the antenna.
