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
+
shelf above the desk saves desk space and neck strain.
+
- The **key, paddle or microphone goes where your hand naturally rests**, and the logging keyboard
+
goes where you can type without moving the paddle.
+
- Use a real **office chair**. This is not a small thing at 0300 in a contest.
+
- **Headphones** beat a speaker for weak signals and for household peace.
+
- Leave a clear space for **paper** — a notepad still resolves a garbled callsign faster than
+
anything else.
+
+
## Power
+
+
- Run **one heavy DC bus** from the supply to a fused distribution block rather than daisy-chaining
+
radios. Anderson Powerpole connectors are the de facto amateur standard and let you swap gear
+
between the shack, the go-kit and the car.
+
- **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.
+
- A small **UPS on the computer and rotator controller** avoids the annoyance of a reboot mid-contest.
+
+
## 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
+
feedpoint. Most computer-generated noise is conducted, not radiated.
+
- 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
+
than one afternoon of tracing.
+
- Bring all feedlines to a **single entry panel** with grounded surge protection rather than through
+
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
+
[RF exposure evaluation](/wiki/technical/rf-safety).
+
- A **fire extinguisher** rated for electrical fires, within reach and not behind the amplifier.
