Dishtronix DWM2104A Watt/VSWR Meter

Many of you asked for a quality meter like our PowerMaster that was less expensive and had analog accurate peak/average reading meter and instead of designing it we found one newly designed and available from Dishtronix.

This meter looks great too!

DWM2104A Cross Needle Peak/Average Watts and VSWR RF Power Meter

If you run an amplifier, and especially a solid state amplifier, you need a good quality active peak reading wattmeter. Peak power from your amplifier can actually be up to 4 times more than what a non peak reading (or a passive peak reading) meter displays. If your current watt meter does not require power or a battery to operate it is a passive meter. Overdriving transistors or tubes leads to distortion and failure of the power devices. Needing many good peak reading meters in our own laboratory and manufacturing facility for the development and testing of RF amplifiers, we developed the DWM-2100A family of product and have decided to offer our customers a top quality watt meter technology at a rock bottom price because every radio amateur on HF with an amplifier should have one of these!

The DWM-2104A is an active peak reading wattmeter with simultaneously variable hold time on both the forward and reflected meter movements. This variable delay can be adjusted for quick action for high speed CW, or for longer periods more appropriate for the display of SSB and AM voice peaks. The peak detectors sport a new fast attack design capable of capturing quick pulses such as a single dit. Beautiful industrial design with tri color meter scale and brilliant LED illumination make the DWM series wattmeter a beautiful addition to any station. Individual scale divisions for each power range offer enhanced accuracy comparable to meters costing several hundred dollars more! If you operate high speed CW and SSB and are looking for an accurate, cost effective meter that works right on all modes, this product is for you! Because it is from Dishtronix, you are assured that it is designed for sustained high power operation!
