📡 Multiple QTHs

Operating from more than one location in a single log — travel, POTA, Field Day? Rayfall reads MY_GRIDSQUARE / MY_LAT/MY_LON from each QSO and groups them:

• Every unique QTH gets its own marker on the map (grouped at 6-character grid precision).
• Each contact popup shows From QTH: so you always know where you were when you made the QSO.
• Toggle Color Pins by QTH to color every contact by its originating station.
• Use the QTHs filter row to isolate contacts from one trip stop.

🔍 Filtering Contacts

• Show Lines: Toggle lines from each QTH to its contacts
• Color by Band: Color-code pins by frequency band
• Color by QTH: Color-code pins by originating station (wins if both are on)
• Band / Mode / QTH Filters: Check/uncheck to hide contacts by band, mode, or originating QTH

The QSO counter updates live as you filter!
