- Turk Telekom GNSS holdover failure -- Calnex ITSF 2026 measurements show base-station timing silently degrades the moment GNSS drops: no re-sync grace, holdover runs out, sync rots underneath. Treat GNSS loss as a hard operational kill, not a nuisance -- the exact failure mode you produce with a $30 GPS spoofer [RNT Foundation].
- PortaPack nightly fixes SD corruption -- n_261115 kills SD write corruption by switching to single-beat SDIO IDMAC transfers, extends PRALINE TX/RX clock sync to the HackRF Pro internal 25 MHz TCXO, and fixes stale audio-spectrum updates on modulation changes. If you trusted the old waterfall during mode switches, rerun your captures [portapack-mayhem].
- KrakenSDR V2 suite rewritten in C++ -- Python is gone: real-time spectrum plus audio demod now runs concurrently with MUSIC DoA, with big speedups on Pi 4/5 and a Mode selector for tuner allocation. Five coherent RTL tuners doing passive DF on a Pi 5, finally without the Python GIL choking the correlation [krakenrf].
- FCC floats 2.4/5.8 GHz satellite use -- AMSAT ANS-319 covers FCC comment rounds on letting satellites into the same 2.4 and 5.8 GHz ISM chunks your Wi-Fi, LoRa, and FPV gear squats in, plus SO-131/SO-132 OSCAR designations and SSTV handling in the OSCAR Watch Tracker v1.1.7 [AMSAT].
- WiGLE Android 2.112 fixes IMS wedge -- toggling Wi-Fi no longer wedges IMS, and a new filter icon shows display/logging/alert state so you know exactly what made it to the log versus what you only saw. Small fix, but the IMS wedge was silently killing captures mid-drive [wiglenet].
- rtl_433 hardens SDR reopen paths -- recent commits fix getopt reset/%z on newlib/ESP-IDF, shrink MAXIMAL_BUF_LENGTH, reopen SDR devices cleanly, and silence connection handlers before mg_mgr_free(). The clean-reopen work matters if you hot-swap dongles on a Pi during long ISM stakeouts [merbanan].

- Bench the C++ MUSIC DoA against the old Python stack -- flash the V2 suite on a Pi 5, feed a known bearing from a handheld transmitter at 433 MHz, and diff DoA accuracy and latency against the legacy Python build to see if the C++ rewrite traded correlation depth for speed [krakenrf].
- Replay GNSS-loss holdover decay on the bench -- feed a u-blox or GPSDO-equipped SDR a clean simulated constellation, then cut it mid-run and measure how long holdover holds phase on your 10 MHz reference before drift kills coherent captures [RNT Foundation].
- Hunt 2.4/5.8 GHz satellite downlinks before the FCC rules land -- point an RTL-SDR or HackRF + helix at the new SO-131/SO-132 passes, record the 2.4/5.8 GHz segments, and characterize what satellite traffic in ISM looks like before it shares spectrum with your Wi-Fi attacks [AMSAT].
- Verify the SDIO corruption fix under heavy capture -- flash nightly n_261115, run long spectrum captures with aggressive SD logging on H2/H4M, and diff card contents against the old multi-beat IDMAC path to confirm the corruption is actually dead [portapack-mayhem].
- Fuzz Meshtastic protobuf framing against v2.8.2.31 churn -- the proto bump can shift wire framing on the LoRa mesh; capture meshtastic traffic with rtl_433-adjacent tooling or a HackRF at 915/868 MHz and diff ToBot decoding before/after the protobuf change [meshtastic].
- Stress rtl_433 hot-swap on ESP-IDF targets -- the newlib getopt fix plus clean SDR reopen means you can now build rtl_433 on an ESP32-S3 with an attached tuner; try it and see how long a 433.92 MHz stakeout survives USB re-enumeration [merbanan].

The custom-radio and DFing desks shipped real metal this window: KrakenSDR ripped Python out of its V2 suite entirely, LimeSDR Micro firmware gained scheduled stream starts and Hann-windowed Rx DFT bin measurement, and GNU Radio 4 pinned components for RC3 while VOLK refactored its 8i_s32f_convert_32f kernel. Meanwhile Kismet merged baseline-transport rules for aircraft and ships, and sdrtrunk bolted a RadioReference overlay onto its spectral display. The signal is in firmware and DSP cores, not advisories.
- krakenrf/krakensdr_suite -- full C++ rewrite dropping Python: real-time spectrum and audio demod run concurrently with MUSIC DoA, Mode selector picks tuner usage, big speedups on Pi 4/5. The coherent-DF stack to beat right now.
- portapack-mayhem/mayhem-firmware -- single-beat SDIO IDMAC transfers kill SD write corruption, PRALINE TX/RX clock sync extends to the HackRF Pro internal 25 MHz TCXO, and stale audio-spectrum updates during modulation changes are fixed. Textbook teardown-order hygiene.
- myriadrf/LimeSDR-Micro_VSPA -- adds scheduled stream start at a specific time, Rx DFT bin measuring with Hann windowing, and trimmed common code. Scheduled start is a quiet TDOA enabler for multi-node captures.
- gnuradio/gnuradio4 -- modern C++ SDR/DSP framework with a high-performance flowgraph runtime; components pinned for RC3 and README workspace/build instructions rewritten. Worth a 10-minute diff against your GR 3.10 flowgraphs.
- kismetwireless/kismet -- baseline-transport merge adds rules that baseline aircraft and ships for the current run only, pairing with the new traffic-filter docs in kismet-web-docs. Clean run-scoped filtering instead of stale global baselines.
- 7h30th3r0n3/Evil-M5Project -- C++ Wi-Fi scan/monitor/interact toolkit for Cardputer, AtomS3, Fire and Core2, with new Evil-* payload binaries shipping alongside the Evil-Flasher WebSerial one-flash app. The ESP32-S3 attack handheld keeps growing.
