Please take some extra time to make certain that the important safety and technical requirements detailed in this chapter are followed closely. ![]() Just route the cable into the appropriate channel provided, as shown in the illustration. Always observe proper polarity when making DC connections: The Red DC power lead connects to the Positive () DC terminal; and the Black DC power lead connects to the Negative () DC terminal. If the voltage is above 15 Volts, the vehicles voltage regulator should be adjusted to reduce the charging volt- age to 14 Volts or lower. A good ground system can contribute to station efficiency in a number of ways: r It can minimize the possibility of electrical shock to the operator. If multiple ground rods are used, they should be configured in a V configura- tion, and bonded together at the apex of the V which is nearest the station location. Use a heavy, braided cable (such as the discarded shield from type RG-213 coaxial cable) and strong cable clamps to secure the braided cables to the ground rods. Additional system bandwidth may be realized using the Yaesu FC-30 Automatic Antenna Tuner, which will present a 50 W impedance to your transceiver on the 1.8 50 MHz bands so long as the SWR on the coaxial line connected to the FC-30. In portable operation, be sure to lay out radials (or otherwise construct a n image plane for the vertical monopole); it is not adequate simply to connect a vertical radiating element to the rear panel Antenna jack of this transceiver, with- out providing a suitable counterpoise. If a lightning storm is in progress in your immediate area, do not attempt to disconnect the cables, as you could be killed instantly if lightning should strike your antenna structure or a nearby power line. These include: r The Antenna Jacks (HF50MHz and 144430MHz); r A TR control line (open circuit on RX, closure to ground on TX); and r A negative-going ALC jack (control voltage range: 0V to 4V DC). If you plan on using multiple linear amplifiers for different bands, you must provide external band- switching of the TX GND. The audio output is fixed at 100 mV, with an impedance of 600 W. DJUSTING THE The two front feet of the transceiver allow the transceiver to be tilted upward for better viewing. SQLRF Knob In the USA version, this (outer) SQLRF knob adjusts the gain of the receivers RF and IF stages. Press and hold in this key for one second to activate the Menu. The selections available are:. MHz 3.5 MHz 5.0 MHz 7.0 MHz 10 MHz 14 MHz 15 MHz. METER Jack This 3.5-mm 2-pin jack is used for connection to an analog meter (not produced by Vertex Standard).
