Documentation

Set your CI-V address, baud rate, and connection type. Add and manage multiple radios, configure callsign, station details, rigctld port, RC-28, lookup credentials, and audio — all from the Settings menu.

Step-by-step instructions to bypass Windows SmartScreen and macOS Gatekeeper so the application can run.

Free license required — register with your callsign and email, then update the app configuration with your key.

Select your radio from the dropdown and click Connect. Use Refresh Settings to sync the app with the radio's current state. Disconnect and Standby buttons for power control.

Tour the full interface — six main tabs, two status tabs, plus secondary windows for config, radio manager, and audio settings. Right-click context menus and spacebar PTT toggle included.

Control frequency, step size, and band selection (2m/70cm/23cm). Set operating mode, filters, split/duplex, VFO A/B, satellite mode, tone, RIT, PTT, and modulation source. Real-time S-meter, SWR, and ALC meter bars.

Adjust RF power, RF gain, USB modulation level, USB AF output, squelch, and noise reduction — all with real-time sliders.

Toggle the internal preamp and enable per-band external preamps (144 MHz, 430 MHz, 1200 MHz) for improved signal reception.

Configure audio codec (one-channel or two-channel), select speaker and microphone devices, adjust stereo balance, and set per-channel volume and mute. In two-channel mode, the left channel carries Main band audio and the right channel carries Sub band audio.

Remove noise from received audio in real time with a neural network that runs entirely on your computer — no audio leaves your machine. Toggle the AI NR switch on the Main Display and blend the effect with the AI NR Level slider on the Levels tab. Works alongside the radio's own NR, with mode-specific guidance and a self-disabling watchdog if your CPU cannot keep up.

Real-time 475-point spectrum display with scrollable waterfall. Pin the display with Fix mode for Doppler tracking, adjust reference level and span, and see saved memory markers overlaid on the frequency axis.

Colour-coded IARU band plan strip on the waterfall. Select Region 1, 2, or 3 in Configuration → General. Hover any segment for category and description. Customise allocations by editing the CSV file in your Pycom directory.

Real-time speech-to-text of received audio through any OpenAI-compatible Whisper endpoint (Groq, OpenAI, or local). Optional LLM cleanup pass extracts callsign, RST, name, and QTH using local Ollama or a cloud LLM. Configure endpoints and API keys in the Transcribe configuration tab.

Record, play, and save up to 8 voice TX audio slots per radio. Right-click any slot to record from your microphone, play it back on the active band, and save it to config. Slot labels are per-radio and persist across restarts.

Control your radio by speaking — tap the capture key (default Left Shift) or say "Okay radio" with the optional wake word, then speak commands to tune, set modes, key PTT, apply memories, connect radios, and more. Full command reference included; wake word detection and grammar run locally, with speech sent only to your configured Whisper endpoint for transcription.

Save the entire radio state — frequency, mode, filters, split, tone, RIT offset, power, and preamps — as a named memory. VFO and satellite memories auto-exchange bands on apply. Includes a downloadable starter CSV with popular satellites and repeaters.

Look up any callsign against QRZ or HamQTH directly from the Logging tab — name, QTH, grid, DXCC, CQ/ITU zones and photo are pulled in automatically. Configure your credentials in Settings.

Log contacts with most fields pre-filled. Sessions are saved as local ADIF files. Upload directly to Cloudlog and LoTW (TQSL required) with duplicate handling by the provider.

Built-in hamlib-compatible rigctld server on port 4532 (configurable). Lets Gpredict and other tools control frequency, mode, VFO, split, PTT, and read signal levels. Includes read-only mode and satellite-aware MAIN/SUB VFO mapping.

Serve a browser-based control page from inside the app — open it from any phone, tablet, or laptop on your home network for the live waterfall, real-time meters, radio control, and push-to-talk using that device's microphone. LAN only, nothing exposed to the internet; works with the IC-9700 and IC-7610 over network (UDP) connections.

Use the Icom RC-28 locally via USB or remotely over the network (TCP port 5100). The dial adjusts frequency or sliders, F-1 changes step size, and the Transmit button holds PTT.

One-click satellite tracking — click Start Tracking and Pycom configures uplink/downlink frequency, mode, and applies continuous Doppler correction via the CSN S.A.T REST API. Re-center with a single button. Configure the base URL in Settings.

Windows-only virtual serial port passthrough using com0com. Configure SatPC32 to connect via a null-modem pair and it drives frequency, mode, satellite, tone, and scope commands directly through Pycom.

Recommended Doppler setup guide — use the built-in rigctld server with Gpredict or CSN S.A.T for automatic tracking, or combine with saved memories for quick satellite band setup. Includes video walkthroughs of full-duplex satellite operation.

Run FT8, WSPR, and other WSJT-X modes through the built-in rigctld server. Covers standard configuration and the special setup needed when running WSJT-X alongside Doppler tracking on satellite passes.

Automatic statistical detection of signals on the waterfall. Colored markers show strong, moderate, and weak signals. Three sensitivity presets (Strong Only, Normal, Sensitive) plus nine tunable parameters for fine control.

Neural network classification of detected signals into 16 types (CW, FT8, FM, SSB, etc.). Capture window for labeling and saving signals. Train or fine-tune the model on your own captures with quality safeguards.

Detailed reference table of all 16 recognized signal types — modulation type, bandwidth, tone count, and typical bands.
