NOTE: The mWattmeter II has been discontinued. It will be replaced with the mWattmeter III. The mWattmeter III will have an upgraded 2X16 backlit display and updates to the firmware to support calibration. It will retain all of the features of the current mWattmeter II.

The mWattmeter II V2 is a low cost QRP combination power and SWR meter kit. It has a power range of 1mW to 20W on all HF bands (including 6 Meters). This kit was originally designed, created and produced by K5BCQ (Kees). Multus SDR now has the rights to produce the kit.
Features Include:
* LCD display
* Multiple Display Modes (6 Modes)
* Good accuracy
* BDM connector (Background Debug Mode)
* I2C connector
* Firmware Upgradable via chip swap

The new V2 model is now a single board implementation. This reduces the number of required wire/solder connections. It now also has an option to attach a potentiometer to vary the contrast of the display.

The mWattmeter II V2 is the perfect companion for the Multus SDR Basic or Proficio (as well as any other QRP rig) providing everything you need to know about the output power of your rig and how well your antenna is matched to your rig.

The mWattmeter II V2 is sold as a kit and contains SMD components. Super glue and one AAA battery are required and are not provided in the kit. Also, additional hook up wire is required if the push button controls and display are to be placed further than the supplied hook up wires allow.

There are four RF connector options available:
1 On board BNC connectors
2 Panel mount BNC connectors (with Coax)
3 Panel mount SO259 connectors (with Coax).
4 No Connectors
Please select one RF connector option (below) when ordering the mWattmeter II V2. Shipping of one connector option is free when ordered with the mWattmeter II V2.
NOTE: If the mWattmeter Enclosure is being ordered please select the On Board BNC connectors option.
