Expert Remote System (ERS) is a remote station control system. ExpertSDR3 is one of its components: the operator application. ExpertStarter runs alongside the SDR equipment at the remote station, while ExpertCloud handles sign-in and connection setup. A web interface is also available.
How ERS works
ExpertCloud: a cloud service for secure sign-in, device management and connection setup between the operator and the remote station.
ExpertStarter: the local server component of ERS. It runs beside the SDR equipment on the same network.
Operator interface: the full ExpertSDR3 application or a browser-based interface.
Benefits of ERS
Eliminates Geographic Barriers: Operate a high-performance station from a location with ideal radio conditions (low noise, excellent propagation) directly from your computer, anywhere in the world.
Enables New Operating Scenarios: Perfect for DX-peditions, contests, extended portable operations, or maintaining your station access while traveling.
Simplifies Station Deployment: Ideal for users who cannot install a full station at their primary residence but have access to a remote site (e.g., a country house).
Who ERS is for
Radio amateurs seeking the highest receive signal quality from low-noise areas.
Operators unable to deploy a full station in an urban environment.
Enthusiasts who frequently travel but wish to stay active in the hobby.
Those who want to evaluate transceiver operation and remote capabilities before purchasing hardware.
