Thanks i'll look those guys up and see what they have! Has anyone here ever used 900 mhz equipment? How well does it work? Is the band similar to 2m or
70cm?
Here's some good info on 900 MHz:
SD900 MHz About 900
900 MHz is a tough band to operate on. It is almost completely ‘line of sight’. Almost anything can block or hinder communications on these frequencies. Even trees! This is why almost all commercial 800 and 900 MHz systems for two-way communication use multiple linked repeaters to cover an area. Using one central repeater to provide mobile coverage over a huge area of real estate rarely works well unless the site is very high (such as a very tall building or mountain) and the surrounding area is relatively flat and clear of obstructions or multiple receivers and a signal-to-noise voter is used. Many Ham 900 MHz repeater systems are used as a fixed-station entry into another repeater system (such as six or two meters) thus keeping the regular repeater inputs open for mobiles and H/T’s, with the audio between the repeaters allowed to mix together (think full-duplex). Some 900 machines are finding handy use as a fixed station entry point into EchoLink and other VoIP systems.
The band does have some interesting characteristics. It bounces off of mountains, buildings, and other solid objects very nicely. And where you have line of sight, very little RF power is needed for reliable communications. And because of the very short wavelength, antennas can be small, yet be designed with very high gain. Dish antennas were popular to use for this band for point-to-point links, giving very high ERP with tiny amounts of transmitter power. Moonbounce operators like the band for its good EME characteristics. And ducting will sometimes carry signals beyond line of sight.
