Switch from getCurrentPosition (which looped via push_patch) to
watchPosition with a 60-second throttle. Break the server-side
request_gps loop by skipping re-request when coords already exist.
- "My Location" button with text label (was just an icon)
- Two share buttons after results:
- "Copy Link" — fixed coordinates, exact result
- "Copy Link (use viewer's GPS)" — source=gps, dynamic per viewer
- CopyLink JS hook copies full URL to clipboard with "Copied!" feedback
Bookmarking /path?source=gps&destination=K5TR&band=10000 will use
the viewer's device GPS to resolve the source location on load.
The LocateMe hook handles both button clicks and server-pushed
request_gps events. Once coords are resolved, the URL is updated
with actual lat,lon and calculation runs automatically.
- TX/RX height in feet (converted to meters for terrain analysis)
- TX power in dBm with mW equivalent display
- TX gain and RX gain (dBi) inputs
- Power budget: TX power + TX gain - feed loss = EIRP - path loss
+ RX gain = RX power vs CW sensitivity = margin
- Loss budget: FSPL + gaseous (O2+H2O) + diffraction + rain
with per-km gas rate detail
- GPS "Locate Me" button using browser geolocation API
- Lat,lon coordinate pairs accepted as input
- Weather displayed in F with C below
- LiveStash preserves form inputs across page reloads
- Terrain cross-section with beam line and Fresnel zone
