The RF313 UHF radio is now available; it supports transmissions over frequencies in the 400 to 430 MHz band.

As with other Maxon radios, the RF313 is compatible with the RF310B base station and the RF310M radio modem.

It is not compatible with other RF systems, including the RF300- RF304 radios, RF95(A) modems, or RF232(A) base stations. An FCC assigned frequency is required to order.
