OnAir 3.2

3.2 follows 3.1. It fixes a long list of reports from users, adds a few features that were asked for, and changes the default look for new installs.

Measured numbers come from OnAir's own test signals, not from over-the-air recordings, unless a line says so.

Things to know first

• Dev A is the default look for new installs. People who already use Classic keep it; they see a one-time notice that says Dev A exists and where to switch back. Small screens start in the touch interface (#139).
• Updates: "check yes, download no" for new installs. OnAir looks for a new version by default and tells you; it downloads one only when you turn that on in Settings. Existing settings are not changed.
• Transmit is no longer blocked by OnAir. The refusal lists, the licence and band checks and the remote-API refusal are gone; transmit warns instead. You are responsible for what you send. The one rule left: nothing is uploaded to the map server while you transmit or for 10 minutes after. In OnAir Web, transmit by listeners is a host setting ("web_allow_tx"), off by default. 11 m (CB) can transmit with a warning.
• A new first-run wizard (4 screens, with the FM step after the region).
• Bandwidth controls for VDL2, TETRA, TETRAPOL and the PSK analyser show the mode's standard bandwidth by default; tick Custom to change it. Anyone who had saved a width keeps it.
• One clock for all modes (#218): the computer clock or the signal's own time, chosen once.

Fixes

• DTMB / CDR (#275): the receiver goes back to the middle channel when the strongest neighbour brings no lock.
• SDRplay (#319): Stop Receiver can no longer freeze the window, and quitting does not abort.
• rtl_tcp (#201): waits for a silent local driver instead of closing the connection.
• HaLow (#192): the scan reaches the outer channels of an 8 MHz BSS.
• DRM (#299): the text message is cleaned before it is shown.
• ISDB-T (#313): the one-seg service plays when the PAT is missing.
• Network radios (#314): one shared list of added network radios for all receivers.
• SpyServer (#321): the tuning range includes the server's IQ centre range.
• Pluto (#316): a scanned network Pluto uses the native driver.
• USRP (#294): receive on RX2 and transmit on TX/RX at the same time.
• KiwiSDR (#257): waits for the rest of a frame after a receive timeout.
• TCI (#248): starts a stopped ExpertSDR3 radio; clearer errors and docs.
• Interface: the big readout digits work in Radio-centre mode and the spectrum / waterfall divider moves both ways (#304); the bottom status cells show Chinese captions (#297); moving Min / Max stops the automatic dB range (#297); "Click centres the spectrum" works in the General Receiver (#301); the View menu had two "Reset layout" items with one ID (#301); the Voice codecs overview no longer asks to accept an accepted notice (#293).
• TX: the TX settings stay readable on the Light skin while transmitting (#320); the APRS / packet Destination field no longer shares an ID with the Destination combo (#302).
• ADS-B (#235): dragging the map no longer deselects the aircraft.
• DMR (#300): UTF-16LE text sent under the big-endian label is read correctly.
• VDL2: the "Advanced: receive bandwidth" control wraps with the rest of the toolbar instead of being cut off at the right edge.

New

• Receive bandwidth by hand for TETRA, TETRAPOL and VDL2 (#274): up to 2 MHz, Auto by default.

• VDL2 session log (#309): every frame with UTC date and time, exported as CSV, JSON or text.

• VDES (#303): positions from AIS-like ASM frames on the map and as NMEA over UDP.

• DVB-S (#322): a single-service signal plays by itself and follows retunes.

• PSK (#308): channel bandwidth by hand, 2.5 to 200 kHz.

• NFC (#271): decodes real 2 Msps captures of a phone reading a card.

• TV (#318): picture shape box: stretch 4:3 to 16:9, zoom, fill.

• LimeSDR (#169): a hint in the radio list when a Mini is plugged in but LimeSuite is missing.

• Documentation: FDM-DUO through its USB sound card (#251); analogue TV status (#73); RTL2832P DVB sticks (#180).

• First-run setup, version 2. Four short screens, each skippable: the radio (found automatically, with a help link per radio, or the test signal), the location (city search, locator or coordinates; sets the country, ITU region, band plan, FM step, DAB band III, TV channels, the ADS-B position and the time zone), the interests (which modes are starred first, the starting mode and starter presets) and a summary with the tour on offer. It shows only when there are no earlier settings, so an update never shows it to existing users. Run it again from Help > Setup and lessons > Run setup again.

• Fast scan v2: Whole span, two-sweep confirmation and spur / image flags; a HackRF firmware sweep with a retune fallback; a dect2fastscan test tool.

• New modes: ROS (detection only, partial), SSDV pictures (uses the GPL-3 fsphil/ssdv code, credited in THIRD_PARTY.md) and Eurobalise / EBICab at 4.234 MHz.

• Icom IC-R8600: a native driver with firmware import (based on work by Topol in collaboration with AI).

• Ham: an 11 m RX button, a ham voice band plan, command line --list-devices, --device and --antenna, and Inmarsat-C EGC area, subject and save.

• Hosting (OnAir Web): TLS (OpenSSL) in the macOS, Linux and Windows packages, the certificate store found automatically, web/onair-web included in every package, the origin fix behind a proxy, docs/HOST-A-RECEIVER.md.

• Decoder quality: the DMR coarse-carrier search no longer follows a strong adjacent channel; P25 and NXDN capture frequencies beyond the channel filter; the AGC no longer ratchets down on repeated bursts.

• Windows fixes: the AVX2 Viterbi stack alignment on MinGW (#324), UTF-8 wide paths for the DRM USAC codec search (#329); also RTL-SDRs that share a serial number (#328) and analog TV / FPV full screen (#326).

Pull requests merged, with thanks

• #327 HFDL: the bits of each ICAO octet are reversed, so aircraft addresses match dumphfdl (frank-1225).
• #295 P25 trunking follows Phase 2 calls from the Phase 1 control channel, and the exact CIC decimator and 8 to 48 kHz upsampler for the voice receivers (Mike, drelectro).
• #315 Chat mode for the Enhanced Sub-GHz Chat app on the Flipper Zero (A2ureIm4la).
• #305, #306, #307 DMR: position history kept across a reset, a bounded and followable map card, NMEA positions in text messages (Vladimir, vlig-alt).
• #311 TETRA: the GSSI of a group call sent to an SSI with a usage marker (Dmitry Obedkov, drfruct).
• #298 Band plan: Portuguese (Portugal) UI picks the CEPT plan, not Brazil's (ffishman).

Known issues

• #254 could not be reproduced; it stays open.
• dvbt_real (a real 7 MHz DVB-T recording) can still differ in the number of damaged packets on x86 CPUs, because the floating-point order differs from arm64; decoding is not broken.
• Decoder quality: P25 with a +40 dB adjacent channel went from 75 % to 67 % decoded, and DMR next to a +30 dB adjacent channel still does not decode.
• Needs a user test (not tried on real hardware or signals): the HackRF firmware sweep, the IC-R8600 driver, ROS and EBICab, Tailscale / Cloudflare hosting of OnAir Web, and the Windows fixes #324 and #329.
• Tests that fail in the project's CI on main as well as in 3.2 (not new): dvbt_real, halow_engine, ham_js8 (Linux), fastscan (macOS), native_netradio, scan_soapy, tx_quality_* and wifi_engine (timing), time_ntp, and on the Windows (MinGW) build about 20 tests such as isdbs, presets, latest_slot, backup, native_tci, mesh_proto_rs, voice_keys, dvbs_vlsnr, iridium_bits and hfdig_kbd. Slow runners also make native_kiwisdr, updater, iono_engine and plugin fail by timing now and then. Three tests that failed on the release candidate (credits, gui_rules, hfdl_proto_rs) and icom_r8600 (it crashed in the USB library on the CI runners) were fixed before release; the fix commits are test-only, and they were not run on GitHub again before this release.
