Information

INTRODUCTION The AR-147 is a VHF two way mobile Transceiver with nominal a RF power Output variable up to 60 watts, it has been developed and tested to stringent specifications. lt‘s designed to operate in the frequency range of 130MHz to 180MHz with a choice of 5, 6.25, 10, 12.5, 20 or 25KHz channeling steps. Three available channel spacing, 12.5, 20 and 25KHz can meet different kinds of need. Advanced surface mount and microprocessor technologies are used to provide many- additional functions and combine to make a very versatile unit. The digitally synthesized mobile Transceiver uses a single crystal for frequency control and a EEPROM for the storage of frequencies and other software definable information. The front panel of the AR-147 has three variable controls, these being a volume control knob, a squelch level control knob and a channel selector knob. A large back litliquid crystal display (LCD) makes the reading of settings easy-even at night. The LCD displays signal strength both in receive and transmit mode, which mode of operation the Transceiver is in and whether it is operating on high or reduced power. Programming of the Transceiver can be accomplished either by PC, or from the function key on the front panel of the unit.
