1. Tune - Displays instantaneous power - for real time response when
tuning your transmitter, amplifier, or antenna tuner.
2. Peak Power - Faster peak power detection than the competition.
3. Average Power - with sensible time constants to provide meaningful
measurements. The only real way to monitor your "talk power".
Surprisingly, the other digital RF Power Meters have only one or
two of these power measurement modes.
And with MB-1's extensive display features, you can display all three
power modes simultaneously if desired.
The only Digital Amateur Radio Power Meter with a real time Analog Meter.
A Digital Power Meter that can actually measure and display your "Talk Power"!
Extensive Digital Filtering for stable and repeatable readings.
Display up to Eight different measurement types simultaneously.
Interface your own Analog Meters and Couplers (including Bird Line Sections) to MB-1. This means that your MB-1 supports all of the frequency ranges that Bird slugs support!
Unique with MeterBuilder: 60 Point Calibration Curve -
Calibrate your own couplers to within 1% of any Measurement Reference.
The website and documentation contain lots of overview and tutorial information. With a MeterBuilder MB-1, you get a lot more more than just a power meter!
Please note - we are accepting U.S. orders only at this time.
If you are looking for a meter to
provide basic functions, there are several simpler alternatives on
But if you are looking for a meter that goes beyond the basics, and if you are the type of Ham who likes to
experiment, customize, and expand the capabilities of your equipment, MB-1 may be a good match for you.
The MB-1 is available in both kit
form and fully assembled and calibrated.
The kit requires soldering. The kit also includes a preassembled coupler with DC voltage/power benchmarks,
and therefore requires only a digital voltmeter for accurate calibration. All components are through-hole (no surface mount components to install).

The MeterBuilder MB-1 is the only digital meter that provides the ability to directly interface to other manufacturers' couplers.
MB-1 can also directly interface to a wide range of external analog meters including surplus meters and meter movements from other manufacturers' equipment.
The photo below shows MB-1 being used with a competitor's coupler, the PowerMaster HF-3K, and an external Analog Meter. The PowerMaster coupler was calibrated with MB-1's Multipoint calibration feature. Power transmitted by a Yaesu Mark V is being applied to a dummy load through the PowerMaster coupler. The Forward and Reflected voltage outputs from the coupler are being fed into an MB-1 coupler port, processed by MB-1's software, and displayed on the 7-segment LEDs, the LCD, and the external analog meter.
The external analog meter below is the meter movement of a Daiwa 801 that has been disconnected from the internal Daiwa coupler and is being driven directly by MB-1 after being programmed using MB-1's Panel Meter calibration feature. Both needles of the Daiwa meter movement are being driven simultaneously by the MB-1. As with passive meters that incorporate crossneedle meter movements, both Forward and Reflected power are displayed simultaneously allowing the SWR to be read directly at the intersection of the two needles. MB-1's high processing rate provides a real time response when used with analog meters, including crossneedle meters.
7-Segment LED Configuration:
Top Left - Instantaneous (Forward) Power
Top Right - Peak Power
Bottom Left - SWR
Bottom Right - Selected Coupler - (PowerMaster coupler is connected to Coupler Port 3)
MB-1 comes standard with RED 7-segment LEDs. Green 7-segment LEDs are included in the Expansion Kit.
Since the 7-segment displays are installed on sockets, they can be easily replaced with other colors as shown in
the picture above. Any .52 inch (13.2 mm) common cathode display that meets the current requirements can be used.
For SSB operation, Average Power is the best indicator of a station's talk power. It is useful for optimizing your audio and compressor settings and helps you to quickly spot when something is not set properly. Then why do the other popular meters recommend that you set the mode to Peak Power for SSB?
You may be surprised to learn that for those digital meters that offer an average power mode, most do not provide a meaningful number when displaying average power.
