Power Supply

For fixed station a low-noise 12-14 VDC power supply is recommended. And for portable operations any suitable 12V nominal battery.

Maximum power output varies with input voltage.

Recommended Voltage for full power is 11-13.8V.

J1-RF is a coaxial female power connector. Its purpose is to supply DC power to the transceiver. The outer shell is negative (-) and the center is positive (+).
