Power is mighty potent, and it sure comes in handy when you're operating electronic equipment ... Like, f'rinstance, that RT-524 or -246 receiver-transmitter Make sure that input voltage is between 22-24 volts when there's a lot of talking to do. A lotta transmitting at more than 24 volts will damage the set, and below 22 volts is not enough power. Normally, the RT's geared for 25.5 volts, since it was designed with 9-to-1 receive-transmit ratio in mind. But, extra transmitting can put the heat on and damage the equipment. No matter what your voltage rate is, never key the transmitter for more than 15 minutes at a time. OFF, THEN ON 50 SAP, NOW NAH' WE NO GET METS AFTERNOON MLOSETS BALL SCORES. ANO- 4 HOW. / So you're operating your vehicle with its radio set on. But what do you do when your turn off the vehicle's igni- tion? Leave the radio on? That's bad, real bad. TRIN If you haven't found out already, IIADO when you leave the radio on and then turn the ignition off or on, the sudden surge of power can give the radio fits. F'rinstance ... it can ruin the filaments in a vacuum tube set like the AN/GRC- 19. And it can knock out the transistors BONE in gear like the AN/VRC-12. MI G- - Remember Turn your radio off MNgHON before you start or stop your vehicle's ON H OFF engine.
