Stations that are comfortable get used. A radio at the wrong height, a chair that hurts after twenty minutes, or a rat's nest of cable that must be untangled before every contact will keep you off the air more effectively than any equipment shortcoming.
The operating position
- Put the radio's front panel at eye level or just below and within easy reach; stacking it on a

- Use a real office chair. This is not a small thing at 0300 in a contest.

anything else.
Power
- Run one heavy DC bus from the supply to a fused distribution block rather than daisy-chaining
- Fuse both the positive and negative leads at the source, sized for the cable, not the radio.
- Keep the AC side on its own circuit if you run an amplifier, and put everything on a switched

strip so the station has one off switch.
Cables
- Separate RF, DC and audio/data runs where you can; parallel bundles couple noise.
- Use ferrite chokes on the ends of USB and audio cables and a common-mode choke at the antenna
- Leave service loops so you can pull a radio forward without disconnecting it.
- Label both ends of every cable the day you install it. Cable ties and a label maker cost less
- Bring all feedlines to a single entry panel with grounded surge protection rather than through
feedpoint. Most computer-generated noise is conducted, not radiated.

a window in three places.
Grounding inside the shack
Bond every chassis to a common ground bus — a copper strap or bar behind the desk — with short, wide conductors, and bond that bus to the single-point entry ground outside. Wide and short beats long and round: at RF, a braid strap behaves very differently from a length of wire.
Small things that pay for themselves
- A switched antenna selector so you can compare two antennas without unscrewing anything.
- A remote coax switch at the entry panel instead of six lines into the room.
- A wall clock set to UTC next to the local one.
- A shelf for the manuals and a printed copy of your
- A fire extinguisher rated for electrical fires, within reach and not behind the amplifier.
