Nominal 25W on VHF (144 MHz) and UHF (430 MHz); roughly 20W on 220 MHz and 350 MHz. Supply Voltage: 13.8V DC ±15% (Negative Ground). Current Drain: Receive (Idle): ~350 mA Transmit (Max Power): 4.0A to 5.5A
Never transmit without an antenna or a 50-ohm dummy load. Transmitting into a high SWR (above 1.5:1) can cause permanent damage to internal power amplifier components. qyt kt7900d service manual
