|It measures no power, just SWR. It worked for me beyond any expectation. The unit is well built. No calibration was needed. Extremely simple to use. The lowest pwr should exceed 2 watts. However at 1.8Mhz the meter is less sensitive and it needs more than 20 watts to read correctly.|
Compared to the Comet CMX-2 that I recently recalibrated, they read nearly the same values. The CMX is more sensitive and can be used even using 1 watt.
Considered that this unit was meant for the CB band, I was surprised I could use it for all the HF. The design is simple, the meter is easy to read. The metal box is nice. No need for calibration and the SCHEMATICS is in the instruction sheet (contrary to the much more expensive Comet CMX-2).
