Station Operations
Part of Radio
Station operations covers the daily practices of running a radio station — scheduling, logging, maintenance, watch-keeping, and the operational disciplines that make a station reliable.
Why This Matters
A radio station is not just hardware — it is a system of people, equipment, procedures, and schedules that together provide communication capability. Hardware without operations procedures fails silently: transmitters fall out of adjustment unnoticed, logs are not kept, scheduled contacts are missed, operators get no practice, and when an emergency occurs, nothing works as expected.
Professional radio operations, developed through maritime practice and military use, codify hard-won experience. The practices of watch-keeping, logging, scheduled contact protocols, and station maintenance schedules exist because stations that followed them remained reliable and stations that did not eventually failed. In a post-collapse community radio network, these practices are equally critical — perhaps more so, since there is no manufacturer support and no trained technician to call.
Operational discipline is particularly important when equipment is marginal or homemade. A factory-made transceiver tolerates some operational sloppiness; a homebrew receiver with drifting components and poor shielding requires careful, systematic operation to use reliably. Know your equipment’s characteristics, document them, work within their limitations, and you will achieve consistent results.
Station Log
Every radio station should maintain a log — a written record of all transmissions, receptions, and significant events. The log serves as: a legal record (should transmissions ever be questioned); a troubleshooting reference (when did a problem first appear?); a scheduling reference (when did we last contact Station X?); a training record (tracking operator development); and a propagation reference (what frequencies worked at what times of day and season?).
Minimum log entries for each contact or transmission:
- Date and UTC time (Universal Coordinated Time, kept synchronized with a reliable source)
- Station identification (your callsign and the contacted station’s)
- Frequency and mode
- Signal reports exchanged (received and sent)
- Subject of communication (brief summary)
- Operator’s name or initials
Signal reports use the RST system: R = Readability (1–5, 5 = perfectly readable), S = Signal strength (1–9, 9 = extremely strong), T = Tone quality (1–9, for CW only, 9 = perfect tone). An RST report of “59” means readable and strong, the ideal. “57” means strong but slightly off-tone. “34” means poor readability and weak signal — difficult conditions. Always give honest signal reports; inflated reports (“59 in the log”) undermine the value of the report and lead to miscalibrated expectations.
Log books should be bound volumes with sequential page numbering, not loose sheets. Entries should be in ink. Errors should be crossed out, not erased — regulatory practice. Completed logs should be stored safely and kept indefinitely. These records have historical value beyond their immediate operational use.
Scheduled Contacts (Skeds)
Consistent, pre-arranged contact schedules are far more reliable than calling and hoping someone is listening. Skeds (short for schedules) specify frequency, time, backup frequency (in case the primary is occupied or propagation fails), and duration.
A typical sked agreement: “We will call on 7.060 MHz USB at 1800 UTC daily. If no contact after 5 minutes, try 3.760 MHz. If still no contact, try tomorrow. Signal check every Sunday at 1200 UTC.”
Post the sked schedule at the station and ensure all operators know it. Missing a sked without notification causes concern — the other station wonders if something has gone wrong. If you must miss a sked, send advance notice through any available channel. If you miss two consecutive skeds, the other party should escalate to emergency status checks.
Propagation affects sked success. A frequency that works reliably in summer may be unusable in winter due to changed ionospheric conditions. Review and update sked frequencies seasonally. Keep a backup sked on a frequency that is less susceptible to propagation changes (e.g., if primary is 14 MHz, backup on 7 MHz or 3.5 MHz will usually work when 14 MHz is closed).
Watch-Keeping
A radio watch is a period of continuous monitoring on a specific frequency, with an operator prepared to respond to incoming calls. The international maritime distress frequency (2182 kHz) was traditionally monitored continuously by coastal stations and ships. This practice — someone always listening — is the foundation of reliable emergency communication.
A community radio network should designate specific frequencies for continuous monitoring. At minimum, the primary network calling frequency should be monitored during all active hours (typically 0600–2200 local time). If manning permits, 24-hour watch should be kept on emergency frequencies.
Watch-keeping duties:
- Monitor the assigned frequency continuously, antenna properly connected
- Log any received transmissions (station, time, frequency, content)
- Respond promptly to calls
- Test transmitter function at the start of each watch
- Check antenna connections and power supply
- Complete and sign the watch log at end of shift
“Silent periods” — mandatory 3-minute silence windows around the hour and half-hour on distress frequencies — allowed operators to listen for weak distress calls that might be obscured by normal traffic. Adopting this practice in a community radio network costs nothing and may save lives.
Equipment Maintenance Schedule
Radio equipment fails when neglected and lasts decades when properly maintained. A written maintenance schedule prevents the gradual deterioration that catches operators by surprise at the worst moments.
Daily: visual check of antenna connections (corrosion, loose hardware); check power supply voltage (battery charge, generator fuel); test transmitter output with dummy load; check receiver sensitivity; log any observed anomalies.
Weekly: tighten all connectors; clean dust from equipment; check ground connections (a corroded ground connection is a common source of mysterious troubles); test backup power; review log for patterns indicating developing problems.
Monthly: check antenna wire tension, insulators, and feedline for physical damage; test all backup procedures; clean and lubricate mechanical controls (particularly variable capacitors and inductors with moving parts); verify calibration of frequency-determining components (especially if the station uses a crystal-controlled frequency standard).
Annually: replace all rubber gaskets and cable jackets showing deterioration; inspect all solder joints; test component values of critical circuits (capacitor values drift, inductor cores can develop cracks, resistors drift high); rebuild any connections showing corrosion.
Keep spare components for every common failure mode: spare vacuum tubes (or transistors) for each type used, spare variable capacitors and coil forms, spare feedline sections, spare power supply fuses and regulators, and a completely backup receiver capable of monitoring primary frequencies.
Operator Training and Skills
The best equipment is useless without trained operators. A radio station staffed by untrained operators will fail in an emergency — not from equipment failure but from operator error: forgotten procedures, garbled messages, wrong frequencies, inability to troubleshoot problems.
Operator training milestones:
- Basic receiver operation: tune to known stations, adjust for best reception, log correctly
- Basic transmitter operation: power on sequence, frequency selection, power level, modulation check
- Routine contact procedure: calling, making contact, exchanging signal reports, closing contact
- Message handling: write, send, receive, and log formal traffic
- Emergency procedures: recognize a distress call, respond appropriately, relay to authorities
- Equipment troubleshooting: identify and correct the 10 most common failures
Train operators under realistic conditions. Run periodic drills — unannounced emergency scenarios during which operators must perform under stress. Cross-train all operators so any operator can handle any position. Document all training in the station log.
An operator who has made 100 scheduled contacts, handled 50 messages, and run 10 drills is a reliable asset. An operator who has only “watched” experienced operators and never operated alone is not yet trained — they are supervised. Do not trust unqualified operators with emergency communications. The difference between the two is hours of supervised practice, which costs nothing but time.
