Radio is more useful when somebody else learns why it works.

Radio started with listening, curiosity and some youthful transmitting that is properly described as unlicensed. The licensed record began in 2004 and grew into a practical mix of local voice, HF, data, digital systems, teaching and field communication.

Radio in practice

Operating, teaching and club work

The station record is stronger when it shows radio being used, not only equipment and menus.

Signal, teaching, field use

Radio is equipment, path, practice, and people.

Usually monitoring: GEARS 147.975 MHz (-600 kHz), PL 110.9 Hz.

Fixed, portable, and mobile radios can take the local watch as operating conditions require. “Usually monitoring” describes the operating plan, not a promise that a particular radio or operator is continuously present.

The station begins outside the radio

Antenna, elevation, path, noise, timing, then equipment.

The Home QTH is less “one antenna system” than a small argument among feed lines. The IC-756 Pro III switches among the Mosley 20/15/10-meter beam and the 80-meter loop, which gets more actual use than anything else; a 40-meter dipole normally joins that switch but is down for replacement. VHF/UHF work is split among the roof-mounted Arrow 2m/70cm J-pole on the secondary FT-897D, a dedicated roll-up J-pole for the shack FT-5DR, a Workman III triple-collinear on the QTH TM-D700A, and a smaller Workman II available for the FT-2400. A quick-connect is next so the FT-5DR can borrow the Arrow when wanted, one radio at a time.

Every fixed antenna path provides a DC or static-drain path to ground. All fixed antennas except the 80-meter loop are fully DC grounded through their antenna and/or switched-feed arrangements. The loop is not fully DC grounded; its lightning arrestor and grounded shunt provide its static-drain path. Those arrangements help discharge static, quiet receiver noise, and support the station’s overall lightning-safety system; they are not a claim of lightning immunity.

The radios matter. The path still gets the final vote.

Field radio

The backcountry supplies honest test conditions.

Snow camping, backcountry skiing, whitewater kayaking, running, EUC travel, and long road trips expose weak power plans, poor cable choices, unrealistic antennas, and software that requires an internet connection to explain why it has no internet connection.

Go-kits are organized by task: voice, position, message, power, charging, antenna, weather, and documentation.

Digital field guides

Stop configuring by folklore.

DMR, C4FM/WIRES-X, D-STAR, NXDN, P25, M17, AllStar and EchoLink now share one K6RCS troubleshooting model: identify the layer, prove it, then move outward.

Callsign first. Route second.

Email and telephone remain the durable public front door. Radio operators can use the station identities and usual hangouts below to evaluate a path or propose a sked; none implies continuous monitoring.

Best for a question that should survive propagation, batteries and whether I happen to be near a radio.

Radio is public and fallible. These routes are not private, not continuously monitored and not appropriate for emergency traffic. Skeds are welcome; publish enough detail to establish the contact without publishing credentials, private schedules or sensitive traffic.
Why POCSAG/DAPNET is not a contact tile yet

It earns a public tile when there is a stable public RIC/capcode and an actual monitoring practice. Owning or configuring a mode is not the same thing as being reachable through it.

Personal radio contact

If the radio route does not fit the question, use the ordinary one.

Email is the durable default. If you want a text reply or radio-related follow-up by SMS, the optional box below is separate and starts unchecked.

Social & sharing

Share-ready artwork

Branded landscape and square artwork are kept with the property instead of hidden in a release archive. The landscape card is optimized for link previews; the square tile is built for social posts and profile-driven sharing.
