Rig control
Your radio, controlled from RadioLog
- Reads and changes frequency, mode and band without touching the radio; the logbook and the digital modes use them.
- Three connection methods depending on your radio; pick the one that suits you best.
- The Hamlib relay lets WSJT-X and JTDX share the control, without fighting over the port.

RigControl: VFO, band and mode in real time.
