ABSTRACT:
A combined Global Position System (“GPS”) and radio system for receiving GPS signals and radio signals is disclosed. The combined GPS and radio system includes a controller that controls a switchable frequency source and a mixer in signal communication with the switchable frequency source. The mixer is capable of receiving both GPS signals and radio signals and producing corresponding intermediate frequency (“IF”) signals in response to receiving a frequency reference signal from the switchable frequency source that has a first switch state of operation that corresponds to the mixer receiving GPS signals and a second switch state of operation the corresponds to the mixer receiving radio signals.
