DWM-4

The LDG DWM-4 is based on the QST construction article in the July 1999 issue. This wattmeter is a microprocessor controlled, multi-sensor power monitoring system that covers HF, VHF and UHF frequency spectrums.

A multifunction display on the front panel allows full control of the meter's menu system. Up to four remote sensors can be connected to monitor multiple transmitters. For example: you could have two HF radios, one tuned for QRP, a VHF and a UHF radio all connected at the same time. You recover a bit of shack space having to have only one wattmeter. Because it comes with a mounting bracket, it can easily be mounted under a shelf or dash. The DWM-4 is fully assembled form and includes two sensors (HF/QRP 1.8-54 MHz 150W and VHF/UHF 140-160, 420-470 MHz 150W). This device requires 11-14 VDC at 75 ma. A power supply is not included, but a DC power plug is.
