Abstract
A transceiver has digital transmitting capability. The transceiver includes an antenna having an input for transmitting signals applied thereto. Signal generating means generate first and second signals having first and second frequencies, and transmission means selectively couple the first and second signals to the antenna input in response to first and second micro commands respectively. A processor receives manually chosen messages for transmission comprised of a series of binary encoded symbols. In response thereto, the processor sequentially generates for a predetermined time interval the first micro command for each one bit and the second micro command for each zero bit to be transmitted.
