RX is a complete AI cockpit for the modern shack — a real-time audio engine with a plugin ecosystem that transcribes, identifies, and logs every contact. Studio-grade noise reduction is just the foundation.

The Workflow

From raw audio to a logged contact

RX does not stop at cleaner audio. It runs a full pipeline that hears the signal, understands who is calling, and files the QSO for you — all on your own PC.

AudioLocal TranscriptionCallsign ExtractionAuto Logbook

Every stage above runs locally. DX Cluster and QRZ.com enrichment are optional, opt-in add-ons.

01Local

Clean the audio

The foundational DSP + AI noise reduction stage strips QRN, hiss, and heterodynes so both you and the transcriber get a clear signal.

02Local

Transcribe locally

A local speech-to-text model turns the cleaned audio into text in real time. Nothing is uploaded — the transcript never leaves your machine.

03Local

Extract the callsign

RX parses callsigns out of the live transcript and resolves the entity with an on-device DXCC lookup — no internet required.

04Local

Log it automatically

The contact is written straight to your logbook (ADIF). Enable optional online plugins to enrich it with QRZ.com or DX Cluster data.

The Plugin Ecosystem

Build your cockpit in the Lab

The Lab tab is where RX becomes more than a filter. Snap plugins into the signal chain to transcribe, identify, and log every contact — and switch anything you do not need off.

The Foundation

A rock-solid audio engine under everything

Great transcription and logging start with a clean signal. RX's DSP and AI noise reduction are the dependable base the plugin cockpit is built on — not the whole story.

Real-Time Engine

Processed locally with latency as low as 35ms — fast enough to sit in your live receive path.

AI Noise Reduction

Two AI engines crush QRN and hiss. It is the clean feed the rest of the cockpit relies on.

Dual-View Spectrum

Input vs. output waterfall — see exactly what the engine strips away.

Wet/Dry Mix

Blend raw signal back in to restore presence while keeping noise crushed.

Auto-Notch & Spectral Subtraction

Kills carriers and broadband hiss before the AI stage for maximum clean gain.

Voice Boost EQ

Psychoacoustic curve at 2.5 kHz — Heil-style intelligibility lift.

Truth in Offline

What is local, and what is not

We will not pretend the whole app is a black box. Everything that touches your audio and logs runs on-device. The only things that reach the internet are optional plugins you switch on yourself.

Strictly local & private

  • Core DSP & AI noise reduction
  • Voice transcripts
  • Callsign extraction
  • DXCC entity lookups
  • Your ADIF logbook

No cloud, no telemetry, no accounts. This part works with your network cable unplugged.

Opt-in, needs the internet

  • DX Cluster

    Fetches live spots from a cluster you choose. Off until you enable it.

  • QRZ.com Lookup

    Sends a callsign to QRZ for name/QTH after you sign in. Off by default.

These plugins are disabled out of the box and clearly labelled inside the Lab tab.

Use Cases

Built for operators who run a complete workflow

Not just an audio cable patch. RX is for serious operators who want the whole loop — hear, understand, and log — handled in one place.

DX / HF

For DX Chasers

Hear weak callers the waterfall hides, then let the transcript catch the callsign and resolve the DXCC entity before you even key up.

Contesting

For Contesters

Keep both hands on the run. Callsigns are transcribed and pushed to your log automatically, so a 48-hour marathon stays fast and accurate.

Portable Ops

For POTA / SOTA

A lightweight engine and a local logbook run all day on a field laptop — no signal on the trail needed to keep a clean, complete log.

Compatibility

Any transceiver, any band

Virtual audio cable integration means RX slots into any shack without additional hardware.
