The Tempo DFD/K Digital Frequency Display is designed to operate in conjunction with Kenwood Transceiver models TS-520 and TS-511S. The DFD/K provides a six digit display of both transmitted and receive frequency. In addition the unit also indicates the true receive frequency when the receive incremental tuning (RIT) control is in use. The displayed frequency is indicated in MHz, kHz, and hundreds of Hz, providing rapid interpretation by the operator. The display is updated approximately 17 times per second, thus permitting instantaneous readout while tuning across the band.
