Control RHR with WSJT-X [Beta]

Last updated on 01 Jun, 2026

This feature is currently in open beta.

WSJT-X version 3.0.0 and later supports the TCI protocol. TCI was originally designed for controlling Expert SDRs, and it is comprehensive enough that we have adopted it as the de-facto standard for RHR station control.

The TCI Protocol carries both audio and CAT data over a single TCP port, making setup a snap. No longer do you need complicated virtual COM ports or audio loopback devices.

Operating

Perform the one-time setup steps below to enable TCI and AutoGrid in WSJT-X.

Then, each time you operate:

  1. Start the LocalMate app. It will run in the system tray - the icon looks like a Yagi antenna.

  2. Connect to any station. Both Flex and Icom radios will work.

  3. Start WSJT-X, or click Retry if it is already running.

Audio and frequency data should automatically begin flowing into WSJT-X.

One-Time Setup
