Research and development necessary for the fabricating of four chronically implantable instruments is described. The complete instrument comprises conditioning for low level biopotential signals, temperature sensing, two subcarrier oscillators IRIG channels No. 9 and 10, a VHF transmitter using FMFM multiplexing with a range of 1200 feet, a remote switch to activate the instrument and a saturated mercury battery of 500 mAH capacity. The VHF receiving station, including the antenna, was supplied as part of the program. Prime design goals were met such as transmitting range, and IRIG and FCC compatibility the design goal for power consumption was bettered by more than two times to give a powered lifetime of more than 30 days.
