# Radio tracker (/trackers/radio)
|
|
|
|
Private (owner-only, 404 for everyone else) tracker for Opa Chiel's scanner hobby.
|
|
|
|
- **Frequencies** (`radio.frequencies`): freq in Hz, mode, band (marine/air/ham/pmr/other), name,
|
|
location, notes, marine channel, tags. Seeded from Opa's lists (airband banks 4-6, marine banks
|
|
7-10) and the extras in his notes (Haagse ronde, KLM ronde, ISS downlink, ADS-B).
|
|
- **Scanner banks** (`radio.channels`): Uniden UBC125XLT layout, 10 banks x 50 channels.
|
|
`/trackers/radio/banks.csv` exports all 500 channels in BC125AT_SS column order.
|
|
- **Nets** (`radio.nets`): days (1 = Mon .. 7 = Sun) and "HH:MM" times in Europe/Amsterdam.
|
|
- **ISS passes** (`radio.iss_passes`, `radio.iss_tle`): computed in `scripts/radio.ts iss` with
|
|
satellite.js from the Celestrak TLE (CATNR 25544) for Gouda (52.011 N, 4.711 E), 5 days ahead.
|
|
- **Log** (`radio.log`): what was heard, linked to a frequency.
|
|
|
|
## Jobs (systemd user timers on stan-ovh, copies in deploy/systemd)
|
|
|
|
- `radio-iss.timer`: daily 04:15 Amsterdam, `bun scripts/radio.ts iss` in the app container.
|
|
- `radio-remind.timer`: every minute, `bun scripts/radio.ts remind`. Sends an ntfy push
|
|
10 minutes before each net with `remind` on and each ISS pass with max elevation >= 10 deg.
|
|
`radio.reminders` makes each reminder fire once.
|
|
- Both read `~/.config/radio.env` (mode 600): `RADIO_NTFY_URL` (ntfy topic URL), optional
|
|
`RADIO_NTFY_TOKEN`. Log: `~/.local/state/radio.log`.
|
|
- `bun scripts/radio.ts upcoming` prints the next 24 h of reminders without sending.
|
|
|
|
## Quiet hours
|
|
|
|
Reminders whose send time (event minus 10 min) falls in 00:00-08:00 Europe/Amsterdam are skipped. Override with `RADIO_QUIET_HOURS=HH:MM-HH:MM` (or `off`) in `~/.config/radio.env`; the page shows the code default (`QUIET_HOURS` in `src/lib/radio/index.ts`). `bun scripts/radio.ts upcoming` marks skipped reminders as QUIET-SKIP.
|

|
|
## Reminders and banks (26 Oct 2026)
|
|
|
|
Reminders are on only for live events worth tuning into: ISS passes >= 10 deg and the Haagse ronde. The routine coastguard broadcasts (weather 13:05/19:05, nav warnings 17:30) and the tentative KLM ronde (Sun 12:30, 3785 kHz LSB, from one observation) are off.
|
|
|
|
Banks 1-3 were filled by `scripts/radio-banks-1-3.ts` (idempotent; run once in the app container): bank 1 ISS + APRS, bank 2 calling channels + Haagse ronde, bank 3 FM repeaters around Gouda from the RDI list, cross-checked with Wikipedia.
