Abstract
Abstract This relates to a marine type radiotelephone which is a frequency synthesized, autotuned high frequency single sideband transceiver. The channels with 100 Hz resolution in the high frequency maritime mobile bands and in the 1.6 MHz to 3.5 MHz band are provided by punched cards preprogrammed for mode of operation and in a binary coded decimal code for transmit and receive frequencies enabling personnel holding a minimum class of radio operator permit to operate the radiotelephone. There is no need to enter the equipment and add circuitry to add channels. Channel program cards are inserted into a front panel-mounted card reader. Hence, channel capacity is limited only by the number of authorized frequencies; and the number of channel programmed cards on hand. Additional cards can be field programmed by means of a simple hand punch, or may be obtained preprogrammed by means of an automatic card punch.
