Logging
#Packet Capture
Menu → Tools → Packet Capture records every packet received on any interface to a file, with its time (UTC) and the interface — for checking coverage, reporting a problem or keeping a record of an event. Start recording / Stop recording; each capture is a new file. Captures can be shared (Share) or deleted.
Replay plays a capture back into the map, station log and packet list — at real time, 10×, 60× or all at once. Replay a file… plays any text file of packets in the usual CALL>DEST,PATH:data form, such as a Stream Log or a raw export from aprs.fi. Replayed packets are only shown: they are never sent on, gated, digipeated, acknowledged or answered.
#Event Board
Menu → Logging & Tracking → Event Board is for public service and club events — a marathon, a cycle ride, a rally, a search. Tap Edit to name the event, list the stations taking part (a call without SSID matches any of its SSIDs) and set the checkpoint radius (default 200 m).
Checkpoints are the named points of the current Map Overlay — load the route's KML or GeoJSON file first. A station has passed a checkpoint when one of its positions came within the radius; the board works this out from each station's recent positions and keeps a log with the times, which survives a restart.
| The board shows | |
|---|---|
| Dot | Green: heard in the last 10 minutes · amber: 10–30 minutes · red: longer · grey: not heard. |
| First line | Callsign, how long ago it was heard, and its speed. |
| Second line | Checkpoints passed, the last one with its time, and the nearest checkpoint now. |
Tap a station for Station Detail. ✉ All sends one message to every station (each to the SSID last heard). ⇪ CSV shares the checkpoint log as a spreadsheet file. Clear log empties it. The board refreshes every 10 seconds while it is open.
#Track Log
Menu → Logging & Tracking → Track Log records your own GPS track. Tap Record to start; the app starts its own GPS listener and logs your position as you move (and with each GPS beacon). The header shows the number of points and the distance covered. Up to 10 000 points are kept.
- Show on Map draws the track in green with a chequered flag at the start.
- Export GPX writes
g7jjf_track.gpx(GPX 1.1 with time, elevation, speed in m/s and course) and shares it — open it in Google Earth, Strava, OsmAnd and similar. - Clear Track deletes all points.
#QSO Log
A simple logbook. + Log QSO (also available from Station Detail, the watch list and Repeater Detail) records callsign, name, QTH, grid, frequency (default 144.800), mode (default APRS), RST (default 59) and notes, with the UTC date and time. If you log the same callsign twice within an hour the app asks before adding a duplicate.
The search box filters the log by callsign, name, QTH, grid or notes as you type. Tap an entry to view it, Edit it or Log Again; long-press to delete. ADIF Export writes g7jjf_qso_log.adi (ADIF 3.1.0) for import into logging programs and LoTW/QRZ uploads; mode APRS is exported as the ADIF mode PKT, and the BAND field is worked out from the frequency.
#Packet Rate
A graph of packets per minute over time, with current and peak rates. Useful for checking a filter or seeing how busy the channel is. It needs at least two minutes of data.
#TX History
Menu → Tools → TX History lists everything the app has transmitted this session — beacons, smart beacons, messages, acks, objects and bulletins — with the time, the interface and the raw packet. Long-press to copy. Use it to confirm what actually went out.
#Stream Logs
With Record APRS stream on (Settings → BEACONING), every line in the Comms monitor — received packets, your transmissions and iGate activity — is appended to a daily file aprs_yyyy-MM-dd.txt. The last seven days are kept. Menu → Tools → Stream Logs lists the files; tap one to share it. Delete All removes them.
