GopherTrunk v0.5.0 — a standalone P25 Phase 2 talker-alias follower harvests aliases off the traffic-channel FACCH-S signalling (no voice tap needed, the way SDRTrunk does with two SDRs), plus a decode-activity-gated power log, shared-front-end overload detection, and a P25 network-configuration / activity-summary report

Reddit — body

**[GopherTrunk](https://gophertrunk.org) v0.5.0 is out** — pure-Go digital-trunking scanner for RTL-SDR / HackRF / Airspy / USRP. P25 (Phase 1+2), DMR (AMBE+2 voice), NXDN, Motorola Type II, EDACS, LTR, MPT 1327, dPMR, D-STAR, YSF, M17, plus APRS, POCSAG + FLEX paging, and AIS / DSC / ADS-B. No CGO, single static binary for Linux / macOS / Windows.

This release is headlined by a standalone P25 Phase 2 talker-alias follower and a set of wideband-engine diagnostics.

**What's new since v0.4.9:**

* **P25 Phase 2 talker-alias signalling follower** (#376). On Phase 2 the alias rides the traffic channel's FACCH-S MAC signalling during hangtime, not the control channel — so on a busy multi-site system, where most grants never get a voice tap and encrypted calls tear down before hangtime, it was almost never decoded. A new signalling-only follower allocates lightweight DDC taps on a `role: wideband` dongle and harvests the alias off the traffic channel independent of the voice pool — the way SDRTrunk does with two SDRs. Enable it per wideband device with `signalling_taps: N` (2–4 suits a busy Phase 2 system); decoded aliases bind onto the RID automatically.
* **Decode-activity-gated power log** (`log.power_log`). An opt-in, rotating per-channel IQ-power log for the wideband engine that only records windows where a protocol (DMR Tier II/III, P25 Phase 1/2) is actually decoding, so idle and off-band channels never appear. Defaults to logging only low-power weak-signal windows — the "decoding but marginal" diagnostic — with `all_windows: true` for a full power time-series.
* **Shared-front-end overload detection** (#749). The wideband engine now flags shared-front-end (RTL-SDR / HackRF) overload on wideband captures, so a swamped tuner shows up as a diagnostic instead of silent decode loss.
* **P25 network-configuration / activity-summary report** (#758) across the CLI, web, and API surfaces — a consolidated view of system identity, topology, and observed activity.
* **Hunt diagnostics + reliability** (#757) — blank-identity hunts are diagnosed, a decode-phase SDR overrun is fixed, and low-power WARNs are clarified.

Heads-up: the v0.x line is still flagged prerelease — actively developed, feedback / captures / bug reports very welcome.

**GopherTrunk v0.5.0 is out** — pure-Go trunking scanner for RTL-SDR / HackRF / Airspy / USRP. P25, DMR, NXDN, M17, analog trunked, APRS, POCSAG + FLEX paging, AIS / DSC / ADS-B. Single static binary, zero CGO.

Headlined by a standalone P25 Phase 2 talker-alias follower plus wideband-engine diagnostics.

**What's new since v0.4.9:**
- **P25 Phase 2 talker-alias follower** (#376) — harvests the alias off the traffic channel's FACCH-S signalling with no voice tap, the way SDRTrunk does with two SDRs. Enable per wideband device with `signalling_taps: N` (2–4 for a busy system); aliases bind onto the RID automatically.
- **Decode-activity-gated power log** (`log.power_log`) — opt-in per-channel IQ-power log gated on actual decode activity, so idle/off-band channels never appear; defaults to weak-signal windows only.
- **Shared-front-end overload detection** (#749) — wideband captures now flag a swamped RTL-SDR/HackRF front end instead of losing decodes silently.
- **P25 network-config / activity-summary report** (#758) across CLI, web, and API.
- **Hunt diagnostics** (#757) — blank identity diagnosed, decode-phase SDR overrun fixed, low-power WARN clarified.
