  • PortaPack Mayhem nightly n_261115 -- 7756e195 fixes stale audio spectrum updates during modulation changes, extends PRALINE TX/RX clock sync to the HackRF Pro's internal 25 MHz TCXO, and kills SD write corruption by switching to single-beat SDIO IDMAC transfers. If you trusted the old spectrum display during sweep captures, rerun them [@portapack-mayhem].
  • KrakenSDR suite rewritten in C++ -- the V2 suite drops Python entirely: real-time spectrum and audio demod now run concurrently with MUSIC DoA, with big speedups on Pi 4/5 and a Mode selector for tuner allocation. Coherent 5-channel passive radar and TDOA work just got a lot more bench-friendly [@krakenrf].
  • Turk Telekom GNSS holdover measurements -- ITSF 2026 data shows when GNSS drops at a base station there is no re-sync grace: holdover runs out and timing/sync degrades silently. Treat GNSS loss as a hard operational failure, not a nuisance -- which is exactly how a low-power L1/L5 spoofer takes down a cell grid [RNT Foundation].
  • AMSAT ANS-319 bulletins -- FCC comments on proposed 2.4 and 5.8 GHz satellite use, plus UNNE-1B/HADES-L earning OSCAR designations SO-131/SO-132. New OSCAR Watch Tracker v1.1.7 adds SSTV handling over Earth view -- fresh 70cm/2m downlinks to hunt [AMSAT].
  • rtl_433 cleanup push -- fixes getopt reset/%z on newlib/ESP-IDF, shrinks MAXIMAL_BUF_LENGTH, reopens SDR cleanly, and silences connection handlers before mg_mgr_free(). The newlib fixes matter if you're porting decoders onto ESP32 for always-on sub-GHz ISM sniffing [@merbanan].
  • Evil-M5Project new payload builds -- the M5Stack Cardputer/AtomS3/Fire/Core2 Wi-Fi scan/monitor/interact toolkit ships additional Evil-* payload binaries, with Evil-Flasher Tab5 v1.5.8 landing as a one-flash WebSerial app with embedded ESP32-C6 firmware and SDIO auto-update [@7h30th3r0n3].
  • WiGLE wardriving 2.112 -- fixes an IMS wedge when toggling Wi-Fi and adds a filter icon showing display/logging/alert state. Small fix, but the IMS toggle wedge was a real capture-killer on the road [@wiglenet].
  • LimeSDR Micro VSPA firmware -- adds scheduled stream start at a specific time, Rx DFT bin measuring with Hann windowing, and trimmed common code. Scheduled start is a quiet gem for coordinated TDOA captures across multiple Limes [@myriadrf].

  • Bench the KrakenSDR C++ MUSIC rewrite against the old Python pipeline -- run the same 5-element coherent capture through both, diff DoA accuracy and latency on a Pi 4, and check whether the concurrent spectrum demod introduces coherent-sample jitter that skews the MUSIC covariance estimate [inspired by @krakenrf].
  • Replay GNSS-loss scenarios with a HackRF signal generator -- feed a GPS-disciplined receiver a clean L1 C/A signal, then yank it and measure holdover drift on the local OCXO/TCXO; the PortaPack's new 25 MHz TCXO clock-sync path makes a handy portable timing reference for the same test [inspired by RNT Foundation].
  • Hunt the new SO-131/SO-132 downlinks -- pull UNNE-1B/HADES-L TLEs, compute passes in gpredict or sdrangel, and capture the 70cm telemetry with an RTL-SDR + SDRangel DSD merge; the FCC 2.4/5.8 GHz satellite docket is also worth reading for future Wi-Fi-band interference angles [inspired by AMSAT].
  • Port rtl_433 decoders onto ESP32 post-newlib fix -- the getopt/%z ESP-IDF fixes mean you can now build a battery sub-GHz ISM sensor sniffer on raw ESP32 RF without the RTL dongle; pair it with Evil-Flasher's SDIO auto-update path for fieldable sensor taps [inspired by @merbanan].
  • Verify the PortaPack SDIO fix under long sweeps -- flash nightly n_261115, run multi-hour spectrum captures to SD, and confirm the single-beat IDMAC transfer change actually eliminated the corruption; also re-check PRALINE clock sync against the HackRF Pro TCXO for TX drift [inspired by @portapack-mayhem].
  • Chain LimeSDR scheduled stream start into a TDOA rig -- use the time-scheduled stream start plus external reference clock input on two Micros to build a poor-man's TDOA passive sensor for ISM or ADS-B, then feed the IQ into the Hann-windowed Rx DFT bins for coarse signal detection [inspired by @myriadrf].
  • Stress-test WiGLE 2.112 IMS toggling on the road -- rapid Wi-Fi/BT/IMS toggling during a drive used to wedge captures; verify the fix holds across a full wardrive and check whether the new filter-state icon actually reflects the logging path or just the display [inspired by @wiglenet].

Quiet blog stretch, but the git wire was humming: HackRF portables got a corruption fix and a TCXO sync path, a coherent DoA rig dropped Python for C++, and the sub-GHz decoder king quietly made itself ESP32-portable. The Meshtastic Android snapshot churn is debug-keyed and rebuilt every push -- pin a real tag before field LoRa work, and note the protobuf bump to v2.8.2.31-snapshot can shift wire framing if you're parsing Meshtastic traffic off-air. Kimocoder's new repo is a shell CLI for wrangling local inference instances -- off-channel for us, but the Wifite2 dev shipping tooling is worth a raised eyebrow. Nothing here is conferenceware; it's maintainers tightening capture paths at 2 AM.

  • portapack-mayhem/mayhem-firmware -- 7756e195 kills SD write corruption via single-beat SDIO IDMAC transfers, extends PRALINE TX/RX clock sync to the HackRF Pro internal 25 MHz TCXO, and fixes stale audio spectrum during modulation changes. Pull the nightly if you capture to SD.
  • krakenrf/krakensdr_suite -- full C++ rewrite dropping Python: real-time spectrum plus audio demod concurrent with MUSIC DoA, Mode selector for tuner usage, big speedups on Pi 4/5. The 5-channel coherent DF rig just became deployable.
  • merbanan/rtl_433 -- getopt reset/%z fixes on newlib/ESP-IDF, MAXIMAL_BUF_LENGTH shrink, clean SDR reopen, and connection handlers silenced before mg_mgr_free(). The ESP-IDF fixes quietly unlock bare-ESP32 ISM sniffing.
  • myriadrf/LimeSDR-Micro_VSPA -- scheduled stream start at a specific time, Rx DFT bin measuring with Hann windowing, and refactored common code; the companion LimeSDR-Micro_FW push adds configurable external reference clock frequency off LA9310_DCS_CLK_HZ.
  • 7h30th3r0n3/Evil-Flasher -- Tab5 v1.5.8 is a one-flash WebSerial app with embedded ESP32-C6 firmware and SDIO auto-update for Evil-M5Project and the AWOK Dual Mini v2; browser-to-radio flashing with zero toolchain is a nice field trick.
