XINTEL™ Radio Intel Monitor

XINTEL™ Radio Intel Monitor (Local ASR)

XINTEL™ is a local-first “radio listener” built for disaster response, SAR, preparedness, and training. It captures audio (RTL-SDR, scanner/line-in, or PC system audio), transcribes speech with local ASR (no cloud), matches your Intel Rules (keywords + regex + built-ins), then emits INTEL HIT events straight into XTOC™ so you can keep working while it keeps listening.

Why it’s a force multiplier:

  • Disaster operations: surface “need medical”, “trapped”, “gas leak”, “evacuate”, “collapse”, “structure fire”, and more — while you’re busy with real tasks.
  • SAR / CERT / volunteer ops: catch location calls and coordinate formats, then push them into the TOC as structured events.
  • Tactical / training / exercises: turn chaotic comms into a searchable intel stream with categories, priorities, and cooldowns.
  • Preparedness monitoring post: keep a continuous watch on legally receivable traffic without tying up your attention.

NEW: ViperGram off-air packet ingest: monitor robust radio-audio bursts from XTOC/XCOM, decode the packet text live, and push it straight into XTOC without copy/paste.

What XINTEL™ is

XINTEL™ is an offline-friendly Windows app that turns audio into actionable intel:
speech → transcript → rule matches → structured Intel Hits. It’s designed to integrate with the X* ecosystem:
  • XTOC™ integration (automatic): Intel Hits are emitted as EVENT (T=9) packet wrappers and auto-imported into XTOC via a local bridge (no copy/paste).
  • ViperGram ingest (automatic): live OFDM radio-audio bursts from XTOC/XCOM can be decoded and forwarded into XTOC as recovered multiline packet text.
  • XCOM™ integration: transcripts are appended to local JSONL logs for later review, filtering, and analysis.
If you can get audio into your laptop, XINTEL™ can watch it. SDR, scanner audio, dispatch streams (loopback), or any legal feed.

NEW: ViperGram live radio-audio packet decode

ViperGram is the X* toolchain audio transport for moving XTOC packet text over any audio path, including handheld/mobile radios. When enabled in XINTEL, it can listen for those OFDM bursts on live audio, reconstruct the original packet text, and inject it directly into XTOC.
  • Use case: generate the burst in XTOC/XCOM, play it into a radio, receive the audio with XINTEL over mic/line-in, loopback, or other audio source, and let XINTEL import the recovered packet into XTOC automatically.
  • Major benefit: this gives you a radio-audio packet path with no TNC, no radio data port, and no special cable requirement.
  • Bridge behavior: XINTEL forwards the recovered multiline packet text over the local XTOC bridge, so chunked packets reassemble correctly instead of losing all but the first line.
  • Compatibility note: it targets the same practical problem as Rattlegram-style audio transfer, but it is not wire-compatible with Rattlegram.
Waveform: mono 16-bit PCM WAV @ 8000 Hz
Lead/tail silence: 180 ms each
Inter-burst gap: 240 ms
Burst edge ramp: 10 ms cosine
Symbol: 1280 useful + 160 guard = 1440 samples = 180 ms
Burst: 7 symbols = 1260 ms total
Carriers: 256 active, bins 112..367, 6.25 Hz spacing
Occupied audio: about 700 Hz..2293.75 Hz
Modulation: differential QPSK
Header: 0x56 0x47 0x01 + profile + burst index/total + payload length + repeats + CRC32
Profiles: Strong=85 bytes/2 repeats, Medium=128 bytes/2 repeats, Normal=170 bytes/1 transmit
  • Decoder path: resample to 8 kHz, detect bursts with cyclic-prefix correlation, differential-demod the payload symbols, reverse interleave/whitening, validate CRC-32, then reassemble multi-burst text.
  • XTOC result: ViperGram packets arrive in XTOC like any other ingest source once XINTEL decodes them.

How it works

Simple pipeline. Powerful results.
Audio (RTL-SDR / Line-In / Loopback)
  → VAD (speech detect)
  → Local ASR transcription
  → Intel Rules (keywords / tokens / regex / built-ins)
  → Intel Hits → XTOC™ (auto-import) + XCOM™ (logs)
In the real world, you tune for signal quality and false positives:
raise/lower VAD threshold, tighten rule types (whole-word vs contains-phrase), and add cooldowns to prevent repeat spam from one conversation.

Audio inputs

Choose the source that fits your kit:
  • RTL-SDR (rtl_fm): tune + demodulate from an RTL-SDR and feed audio into transcription.
  • Scanner / handheld radio line-out: run the speaker/headphone output into a USB audio interface or line-in.
  • PC system audio (loopback): monitor anything you’re already listening to (stream, SDR software, comms app) and let XINTEL™ watch it.
Tip: better audio = better intel. Clean the chain before you chase “better AI”.

Rules that match how people actually talk

Intel Rules are designed for fast setup under stress:
  • Contains phrase or Whole word/token matching (reduce false positives).
  • Regex (advanced) for power users (callsigns, IDs, patterns).
  • Built-in detectors: 10-codes and coordinate formats (great for surfacing actionable traffic).
  • Category + Priority for triage (MED / FIRE / SAR / OPS, etc.).
  • Cooldown timers to prevent repeated hits from a long exchange.

Accountability: optional audio clips on hits

Transcripts are fast, but audio is truth. When enabled, XINTEL™ saves a short audio clip around each Intel Hit and includes a local playback link in the XTOC Event note so an operator can confirm context.
  • Review the hit in XTOC™ → Intel and play the clip.
  • Keep proof of what was actually said (useful for after-action and accountability).

Local-first by design

  • No cloud transcription: ASR runs locally (CPU).
  • No accounts: logs and settings stay on your machine.
  • Offline-friendly: activate once online (license), then keep running offline on that device (ASR model included in the download).

Safety & compliance notes

You are responsible for complying with local laws and only monitoring transmissions you are legally allowed to receive.
XINTEL™ is an assistive monitoring tool — not a guarantee of accuracy. Always verify critical information with an operator before acting.

FAQ

Does XINTEL™ require internet?
Only for first-time license activation (if licensing is enabled). After that, XINTEL™ is designed to keep working offline on that device (ASR model included in the download).

Does it require a server?
No. XINTEL™ runs locally and connects to XTOC™ over localhost/LAN.

What radios does it work with?
Anything that can produce audio: RTL-SDR (via rtl_fm), a scanner/handheld radio line-out into your PC, or PC system audio (loopback).

Where does it store data?
Under your user profile (example: %LOCALAPPDATA%\\XINTEL\\) including config, logs, and optional audio clips.
