Page 2: Theory Of Operation
HANDBOOK OF OPERATING AND MAINTENANCE INSTRUCTIONS RECEIVER CONTROLLER RC-1T4A 1.0 GENERAL The model RC-1T4A controller has been specifically designed to provide remote control of heliport lighting systems which require two control functions. This control system will allow the approaching pilot to select either of two operating modes at his discretion. The RC-1T4A is enclosed in a weather-proof water-tight housing and is conservatively designed for continuous outdoor unattended operation. - Page 3 FIG A Functional Diagram...

- Page 5 3.1 RADIO FREQUENCY/DECODER CARD (C.I. PART #11-0255) The radio receiver is a superheterodyne design operating at a nominal R.F. frequency within the VHF band of 118 to 136 MHz. An IF frequency of 10.7 MHz is utilized with the bandwidth controlled by a 6-pole crystal lattice filter. This filter establishes nominal -60 db rejection at adjacent channel frequencies of ±25 KHz or more.
