Shore-based receiver responds to four signal frequencies in 60-kc region, at levels as low as 1 microvolt, coming from receiving hydrophone through up to 15,000 feet of 120-ohm underwater cable. Output of cathode follower V6B is connected to four Foster-Seeley discriminators (not shown) that demodulate signals for driving recorder. Used in monitoring performance of four underwater mines while test ship passes over.-M. J. Aucremanne and D. D. Woolston, Telemeter System Relays Undersea Ordnance Data, Electronics, 31:41, p 84-87.
