v1.9.6 — POTA/SOTA ADIF fixes, wheel-to-tune, iOS bar menus

POTA and SOTA logging put right, the mouse wheel tunes the radio, and the bottom-bar
menus work on a phone again. Almost all of it came from field reports in the two days
after v1.9.4 - Don Adams WB0LQW went through the ADIF file field by field after four park
activations, and the rest arrived from people using v1.9.4 and v1.9.5 on the air.

Logging — from Don Adams WB0LQW's report after four park activations

• Your callsign is written as STATION_CALLSIGN, the field POTA reads. It used to warn "No station_callsign field, assuming operator …" on every upload, and guess.
• Park-to-Park and Summit-to-Summit contacts can be entered afterwards. A new P2P ref column in the web log editor: type just the reference — US-1241, G/LD-049, DLFF-0123 — and the Tab5 works out the programme and fills in both fields. It refuses a reference with no dash, because that value goes out as a claim that a specific park was worked.
• FT4 is logged the way the ADIF specification defines it: MODE=MFSK with SUBMODE=FT4. Editors like ADIFMaster refuse to open a file that declares FT4 as a mode at all. LoTW uploads are unchanged — the pair is turned back into FT4 before signing.

Records already in your log keep the old spellings; only new contacts change. The Today only download gives you a clean file for an activation.

The mouse

• The wheel tunes the radio over the spectrum and waterfall: 10 Hz a click in CW and the digital modes, fine enough to zero-beat by ear, and 100 Hz in SSB (Roy KI0ER, John Dusek). It stops at the band edges, and anything covering the panadapter takes the wheel instead.
• It no longer scrolls panels into blank space — winding past the last row of the settings list or the log used to carry the contents off the screen (Roy KI0ER).

Updates

• The bottom-bar menus work on an iPhone again. A line added for portrait mode in v1.9.4 made Safari hide those popups behind the page (Travis AK6TB, Randy N4OPI).
• "Check for updates" stops claiming you are up to date while it is still asking (Michael KZ4LY, Samuel W7STF).
• Background downloading is now a switch — Tab5 Settings → Network, or the web Settings → Updates. Off still tells you a new version exists; it just waits before spending 3.3 MB (Michael KZ4LY, Samuel W7STF, Steve N9SZ). Nothing has ever installed itself, and that has not changed.
• An automatic download now waits until the Tab5 has settled after boot and has memory to spare (Steve N9SZ).

Also

• Coming back from the radio's own menus restores your frequency and mode — a trip through them could leave the radio on 160 m (Randy N4OPI).
• Basic/Expert is remembered across a reboot (Samuel W7STF).
• A re-sent signal report now carries a fresh measurement rather than the one from when you first called.
