DBHamPlot vs SVXLink

Compute distance and bearing using Maidenhead location. This was originally intended for use by amateur radio operators who participate in microwave communications however it can be used by any ham in order to determine a distance and bearing to another radio amateur. This version specifically for the iPad provides map and controls all on one screen. The larger map area over both iPhone versions should prove helpful. You get a map of the source and target along with a pin annotation and an overlay identifying the six-digit grid area. If a user touches an empty location on the screen for one second a new annotation is added at that spot identifying the grid. Any user-added annotations are removed if a new source or target are entered. This feature is great because you can zoom in on a location, touch the screen, and get a 6 digit grid; this is especially handy when your microwave buddy pulls over to the side of the road to make a contact with you (or someone else) but he/she has no idea what their grid square is.

Control your RF.Guru hotspot over Bluetooth, watch the live feed, send DTMF, and explore the live reflector map from iPhone or iPad. HotSpot is the official mobile companion for the Analog HotSpot SVXLink platform. Pair once over Bluetooth Low Energy and the app takes over from there: read live SVXLink state, switch talkgroups, send DTMF, watch the reflector network on a real map, and keep an eye on your 4G uplink. What you can do: • Live state feed — callsign, frequency, current talkgroup, active and last talker, TX/RX flags, plus 4G signal bars when an LTE modem is fitted. • DTMF & device commands — full DTMF keypad with quick buttons (status, parrot, IP-announce) and a control menu for SVXLink start / stop / restart, 4G on / off, reboot and power-off. • Talkgroup quick-dial — buttons highlighted yellow for the talkgroups your hotspot is actively monitoring, grey for switchable ones, with a green "last heard X ago" timer on each when the live feed is on. • CTCSS info — output tone and the full input-CTCSS → talkgroup mapping shown on the Hotspot Info screen. • Live reflector map — OpenStreetMap-based view of every node on your reflector. Spiderfy clustering, colour-coded pins (red transmitting, green ON0 repeaters, orange nodes, blue AI-detected, grey offline), floating callsign labels on active talkers, and a glass info card on every pin tap. • Home radius — saves your QTH from GPS and frames the map at a configurable radius (default 150 km). One-tap re-center. • Reflector talker history — live, server-paged list of who's been on the network, sourced from the same WebSocket feed. • Auto-everything — auto-connect to your last hotspot on launch, auto-detect WSS support per reflector domain, auto-fetch the talkgroup labels from the portal, and fall back to Bluetooth-only mode when there's no internet. • Keep-screen-on with auto-sleep — optional, slider from 0 (never sleep) to 120 min. • Just Works pairing — no PIN, no fuss.
