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.
Every stage above runs locally. DX Cluster and QRZ.com enrichment are optional, opt-in add-ons.
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.
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.
Extract the callsign
RX parses callsigns out of the live transcript and resolves the entity with an on-device DXCC lookup. No internet required.
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.
Local & Private
Voice Transcription
A local speech-to-text model captures every over as searchable text. No cloud, no upload.
Local & Private
Callsign Extraction
Pulls callsigns out of the live transcript so you never miss one in a pile-up.
Local & Private
Auto Logbook (ADIF)
Writes each contact straight to your log with time, band, and mode already filled in.
Local & Private
DXCC Lookup
Resolves the country/entity for any callsign from an on-device database.
Opt-in · Internet
DX Cluster
Cross-references live spots to prioritize the calls worth chasing.
Opt-in · Internet
QRZ.com Lookup
Optionally enrich a logged contact with name and QTH from your QRZ account.
Plugins marked Opt-in · Internet are disabled by default and only reach the network after you turn them on and sign in.
The Foundation
An audio engine under everything
Great transcription and logging start with a clean signal. RX DSP and AI noise reduction are the dependable base the plugin cockpit is built on.
Real-Time Engine
Processed locally with latency as low as 35ms, fast enough to sit in your live receive path.
Noise reduction
Two processing engines reduce QRN and hiss. How much they help depends on the signal and the settings.
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 processed noise down.
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.
Selectable Processing Modes

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 / HFFor 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.
ContestingFor 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 OpsFor 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
Works with radio audio
RX can process audio from most transceivers and SDR applications through standard audio devices or virtual audio routing.

What RX is not
A tool, not magic
RX cannot recover information that was never present in the received signal.
Noise reduction can improve intelligibility, but aggressive processing may also introduce artifacts.
Results depend on the signal, interference, receiver audio and processing settings.
