ve Ni Com CHAPTER 1 GENERAL DESCRIPTION NT 500 Transmitter Exciter INTRODUCTION The NT 500 LCD Exciter is the latest in state of the art products available from Ni com. This Transliterate is designed with high reliability components and is intended to give many years of trouble free continuous service. This unit incorporates many features including a switching power supply and a PLL frequency synthesizer.
3 Ni Com STARTING PROCEDURE Connect the ante rig cable to the "N connector on the back of the unit. The antenna system must be set up to operate at the transmitter's working frequency. ATTENTION Antenna marching is extremely crucial for FM transmitters. Operate this unit only after verifying good matching. Mismatching will decrease the communication distance and unduly stress the semiconductors. Turn on the transmitter. You should see the "WAIT" message appear on the LCD Display.
