The meter requires a DC power source, which can be provided by a separate power supply or by tapping into the power supply of the radio itself.
In summary, the HM-2102 Heathkit VHF Wattmeter is a reliable, versatile, and easy-to-use instrument for measuring power output and SWR in VHF radio systems. Its rugged construction, large meter, and simple operation make it an excellent choice for amateur radio operators who value accuracy and reliability in their equipment. This pre-owned unit is in good working condition and has been well-maintained, making it a great value for those looking to add a high-quality wattmeter to their radio setup.
