This manual provides installation and operation instructions for the SWR-3 SWR/Power Meter, a device for checking transceivers and measuring RF power.
The SWR-3 is a compact device designed for amateur radio stations to check transceivers. It uses a bridge method to compare voltage supplied to and reflected from antenna systems, allowing for accurate and quick antenna matching. Additionally, it measures RF power using a carrier detector and can function as a field strength meter when connected to a small pickup antenna.
