- KrakenSDR V2 suite rewritten in C++ -- Python is gone; real-time spectrum and audio demod now run concurrently with MUSIC DoA on Pi 4/5, with a mode selector for tuner allocation. Coherent 5-channel passive radar and TDOA work just got a lot more bench-viable [@krakenrf].
- PortaPack Mayhem nightly n_261115 -- 7756e195 fixes stale audio spectrum updates during modulation changes, and the mainline push kills SD write corruption via single-beat SDIO IDMAC transfers plus PRALINE clock sync to the HackRF Pro's internal 25 MHz TCXO. If you trusted the old spectrum display during sweeps, rerun those captures [portapack-mayhem].
- Turk Telekom GNSS holdover measurements -- ITSF 2026 field data: when GNSS drops at a base station, holdover runs out and timing/sync degrades silently. No grace period, no alarm -- GNSS loss is a hard operational failure, which is exactly what a jammer at 1575.42 MHz buys you [RNT Foundation].
- FCC comments on 2.4/5.8 GHz satellite use -- AMSAT ANS-319 covers FCC filings on ISM-band satellite uplinks plus UNNE-1B/HADES-L earning SO-131/SO-132 designations, and the OSCAR Watch Tracker v1.1.7 adds SSTV handling over Earth view. Worth watching if you hunt 2.4 GHz bird downlinks [AMSAT].
- rtl_433 cleanup pass -- getopt reset/%z fixes for newlib/ESP-IDF, a shrunk MAXIMAL_BUF_LENGTH, clean SDR reopen, and connection handlers silenced before mg_mgr_free(). The ESP-IDF angle means more people are porting ISM decoders onto 2.4 GHz-capable SoCs [merbanan].
- Evil-M5Project ships new Evil-* payloads -- the Cardputer/AtomS3/Core2 802.11 scan/monitor/interact toolkit pushed fresh binaries, with Evil-Flasher Tab5 v1.5.8 landing as a one-shot WebSerial flasher embedding the C6 firmware with SDIO auto-update [@7h30th3r0n3].
- Kismet baselines aircraft and ships -- baseline-transport merge adds per-run rules that baseline ADS-B aircraft and AIS ships, so your wardrive captures stop drowning in transient targets. Docs for the traffic filter landed in kismet-web-docs the same day [kismetwireless].

- Bench-test the KrakenSDR C++ MUSIC rewrite -- point the 5 coherent RTL tuners at a 2.4 GHz beacon or a 433 MHz keyfob and diff DoA accuracy against the old Python pipeline; the concurrent spectrum/demod path means you can now DF while listening to the target's modulation.
- Re-verify PortaPack sweep captures post-fix -- the stale audio spectrum bug means modulation-change sweeps on H1/H4M may have shown garbage; redo your 315/433/868 MHz captures on n_261115 and diff the spectrograms before trusting any old logs.
- Measure GNSS holdover decay on your own timing gear -- feed a u-blox or GPSDO through a cheap L1 jammer (or just disconnect the antenna), log the 1PPS drift vs a rubidium or disciplined counter, and see how many minutes your bench sync actually survives -- the Turk Telekom answer is "fewer than you think."
- Port rtl_433 decoders onto ESP32-S3 -- the newlib/ESP-IDF getopt fixes signal active embedded porting; pull the 433.92 MHz FSK/OOK decoders onto an S3 with an SX1278 or direct RF sampling and build a pocket ISM sniffer that pairs with Evil-M5Project hardware.
- Hunt 2.4 GHz satellite downlinks per the FCC filings -- read the comment cycle on proposed 2.4/5.8 GHz satellite use, then park an RTL-SDR or HackRF on the published UNNE-1B/HADES-L pass frequencies with the OSCAR Watch Tracker SSTV handling and see what actually leaks down.
- Fuzz the LimeSDR Micro scheduled stream start -- the new time-scheduled stream start plus Rx DFT bin measurement with Hann windowing is a clean primitive for timed TDD bursts; test start-time jitter against an external 10 MHz reference and see if you can build a repeatable pulse-Doppler bench.
- Chain WiGLE 2.112 into an ADS-B/AIS wardrive -- the IMS wedge fix means Wi-Fi toggling no longer wedges the radio stack mid-drive; pair it with Kismet's new aircraft/ship baselining on the same handset for a combined 2.4/5 GHz + 1090 MHz + 161.975 MHz mobile capture rig.

The custom-radio desks were the story today: KrakenSDR ripped Python out of its V2 suite and rebuilt DoA processing in C++ so MUSIC runs alongside live spectrum and audio demod on a Pi, while the LimeSDR Micro VSPA firmware gained scheduled stream starts and Hann-windowed Rx DFT bin measurement -- both moves that push coherent multi-channel work closer to field-deployable. PortaPack Mayhem quietly fixed SD card corruption by switching to single-beat SDIO IDMAC transfers and extended PRALINE TX/RX clock sync to the HackRF Pro's 25 MHz TCXO, a fix anyone doing long captures off an H4M should flash immediately. Meanwhile GNU Radio 4 pinned its components for RC3 and volk refactored the 8i_s32f_convert_32f kernel, and Evil-Flasher turned into a one-flash WebSerial app with embedded C6 firmware.
- krakenrf/krakensdr_suite -- full C++ rewrite dropping Python; real-time spectrum plus audio demod concurrent with MUSIC DoA, big speedups on Pi 4/5, and a mode selector for tuner usage. The reference architecture for cheap 5-channel coherent DF.
- portapack-mayhem/mayhem-firmware -- SD write corruption killed via single-beat SDIO IDMAC transfers, stale audio spectrum fixed during modulation changes, and PRALINE TX/RX clock sync extended to the HackRF Pro internal 25 MHz TCXO. Textbook teardown-order fix.
- myriadrf/LimeSDR-Micro_VSPA -- scheduled stream start at a specific time, Rx DFT bin measuring with Hann windowing, and trimmed common code. Timed TDD burst capture just got a firmware primitive.
- gnuradio/gnuradio4 -- RC3 component pins and rewritten workspace/build instructions in the README; the modern C++ flowgraph runtime is close to a real release candidate.
- 7h30th3r0n3/Evil-Flasher -- Tab5 v1.5.8 is a one-flash WebSerial app with embedded C6 firmware and SDIO auto-update for Evil-M5Project and the AWOK Dual Mini v2. Flash-and-go for the Cardputer 802.11 toolkit.
