FT-950 Operating Manual Power Connection The DC power connector for the FT-950 must only be connected to a DC source providing 13.8 Volts DC (±10 %), and capable of at least 22 Amperes of current. Always observe proper polarity when making DC connection: The RED DC power lead connects to the Positive (+) DC terminal: and The BLACK DC power lead connects to the Negative (–) DC terminal. We recommend the use of the FP-1030A AC Power Supply. Other models of power supplies may be used wit

FT-950 Operating Manual impedance at the desired operating frequency. While minor excursions from the 50-Ohm specification are of no consequence, the transceiver’s Automatic Antenna Tuner may not be able to reduce the impedance mismatch to an acceptable value if the Standing Wave Ratio (SWR) present at the Antenna jack is greater than 3:1. Every effort should, therefore, be made to ensure that the impedance of the antenna system utilized with the FT-950 be as close as possible to the

If multiple ground rods are used, they should be positioned in a “V” configuration, 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 cable(s) to the ground rods. Be sure to weatherproof the connections to ensure many years of reliable service. Use the same type of heavy, braided ca
