Micro908 Antenna Analyst
The Micro908 is a flexible and re-usable control platform for ham radio projects. The Micro908
platform is designed to be easily operated on the bench as well as in the field. It is comprised of a
single 5” x 5” printed circuit board containing all components, connectors, controls, LCD, and two
daughtercards. The plastic enclosure contains an 8-cell AA battery back enabling convenient field
use. A number of standard ham radio peripherals may be connected to the Micro908: antenna,
paddles, a PC-style keyboard, headphones, an audio line to drive an SSB transceiver, a keyline to
drive a transmitter, your rig's audio in/out signals, and custom control lines via an auxiliary jack. The
first major software available for the Micro908 platform is the
Antenna Analyst – an instrument that
automatically determines SWR and complex impedance characteristics of an HF antenna system.
Advanced features of DDS frequency control, LCD tuning, PC data collection and plotting, numerous
operating modes and easy software upgradability make this instrument attractive for homebrewers and
antenna enthusiasts.
