MOAS II switches antenna relays and similar devices. It is controlled by a computer through a USB interface. This switch will control up to 64 independent relays. Each group of eight outputs can be built for high or low side switching (source or sink). The difference between a source and sink output is invisible to software.

It connects to the amplifier keying lines of the transceivers and optionally to the inhibit inputs so it can avoid hot-switching and it can select different antennas for transmit and receive.

With the provided software it can handle complex antenna systems with multiple stacks, electrically rotatable antennas such as 4-squares, shared antennas for transmit and receive, triplexers, single-band and shared amplifiers, and complex inhibit rules.

And it allows hams to build stations with antenna configurations that could not be reasonably controlled by a manual system.

MOAS II was designed by Paul Young, K1XM. This editor was built by M1DST — m1dst.co.uk.
