Unique and the most advanced "combo" controller for Antenna Switching, SteppIR control, Rotator control and automatic Power Amplifier support available today. Microham Station Master is a unique controller on the market designed mainly for small or moderate, multiple antenna, single rotator/SteppIR or UltraBeam stations. Provides radio control, antenna switch control, band pass filters switching, selective SteppIR or UltraBeam tuning, computer controlled rotator interface, interface for automatic power amplifiers, sequencer for receiving antennas and many additional features.

The interface is suitable for connecting any type of transceiver that has a CAT port. For example, Yaesu, Kenwood, Icom, Elecraft, Ten-Tec.

Microham Station Master box contains: product, installation CD, power connector (the power cord must be made by you), USB A/B cable, clip on ferrit rfi filter, PS/2 cable (mini DIN 6), RCA/RCA cable, DB15 male connector. 

The device is compatible with a wide range of radios, so you need to create a radio-specific cable, it is not supplied in the box. If necessary, we can manufacture these cables and you can ask for our unique quotation! Cabling and device setup can be downloaded here: http://www.microham.com/contents/en-us/d137.html
