Built for Real Stations

MOAS II is the control layer for stations where manual switching is no longer practical. It combines the MOAS switch, server, and clients into one operating model that keeps routing decisions safe, predictable, and quick.

It is designed for serious multi-radio operating where mistakes are expensive:

• deterministic relay switching
• hot-switch protection and inhibit-aware transitions
• automatic antenna selection by frequency
• rotator control for physical and electronically rotatable systems
• remote network operation over local or wide area links

Why MOAS II

The docs describe capabilities that directly reduce operator workload while improving station safety.

Safety and Conflict Handling

• Prevents relay changes on transmitting radios to avoid hot switching
• Models antenna conflicts and prevents unsafe selections
• Supports wait or interrupt behavior during in-QSO antenna changes
• Supports inhibit logic (always, same-band, and operator-controlled modes)

Smarter Routing for Complex Topologies

• Handles alternate paths automatically when more than one route can reach an antenna
• Supports shared antennas and shared systems across radios
• Supports TX-only, RX-only, and split TX/RX operation where hardware allows
• Supports scenarios, overrides, and advanced function control

Rotator Control Included

• Supports rotator-aware antennas and direction selection from clients
• Supports physical rotators and electronically rotatable systems
• Supports distributed rotator control with MOAS Rotator on one or more networked computers
• Supports common rotator families documented in the rotator guide

Multi-Platform, Background-Friendly Server

• V2 server runs on Windows, Linux, and macOS
• Prebuilt binaries and Docker images are available
• Runs as a low-overhead background process with TCP/IP clients
• Configuration-driven workflow with validation and restart-on-change behavior

What You Can Build

MOAS II is intended for stations that need reliable automation at scale:

• SO2R and multi-single stations
• multi-multi shared resource environments
• stacked arrays and switch matrices
• triplexer and shared amplifier workflows
• 4-square and directional receive/transmit systems
• stations that require coordinated antenna and rotator decisions under load

MOAS Platform

MOAS Server

Multi-platform control core for switching logic, station state, conflicts, functions, and network client communication.

Start here: Server overview

Rotator Integration

Integrated rotator model with client-facing direction control for physical and electronic rotation workflows.

Learn more: Rotator documentation

Visual Configuration

Build and validate complex configurations visually, then deploy to the server. Configuration drives behavior across switches, radios, scenarios, and clients.

Operator Clients

Multiple client models are available, including button-driven and rotator-aware interfaces, with integrations for real operating workflows.

See clients: Client documentation

Project Lineage

MOAS II was originally designed by K1XM. This platform builds on that foundation with a modern multi-platform server, updated tooling, and documentation focused on real-world station operation.
