One DC-1 coupler is included with each Watt Meter (DWM-2). At the time of ordering, you can choose if you want the DC-1-30 (for high frequency) or the DC-1-50 (for 6 Meters).

The DWM-2 Digital Reflectometer has been carefully designed and aligned to NIST traceable standards. The DWM-2 is fully capable of measuring power and VSWR from less than 1 watt to 2 kilowatts and 1 to 60 MHz without slugs or exchanging directional couplers. The instrument was designed for ease of use and simple setup.
The DWM-2 is extremely valuable in environments where peak to average power ratios can be extreme as well as in pulse power environments. The instrument is at home making measurements of conventional AM/FM/SSB/CW/RTTY/SSTV transmissions as well as digital PSK31, 16, 64 and 256QAM digital constellations. Use in industrial, scientific, and medical (ISM) settings is equally straightforward where peak power measurements are important as well as average power.
The instrument provides the best of both worlds – digital gauges for accurate data and analog instruments for relative tuning applications.
In environments where very low receive signal amplitudes are expected, the DWM-2 stands proud. No digital signals are processed within the directional coupler thereby ensuring the quietest receive environment possible.
The DWM-2 sports a resistive touch panel interface for the user. Just a simple light touch will suffice for making changes to the operational behavior of the DWM-2. No switches to wear out or to get dirty over time. In addition, the DWM-2 was designed with both low power and high power operation in mind.
The measurements are accurate over an extremely wide range of input power, and the insertion loss is minimal.

PTRX-7300 Panorama Adaptor for the IC-7300
A panorama adapter for the IC-7300? What's the point, you might ask, the IC-7300 has such a nice spectrum and waterfall display? Right, but unfortunately the IC-7300 has no output for an external display....
