The UM200C transmitter is a high performance synthesized UHF design that offers the frequency agility needed to alleviate interference and frequency coordination problems in travelling applications. Interference caused by television broadcasts and other radio equipment can easily be avoided with 256 available frequencies selected in 100kHz steps with two rotary switches on the side panel.
