Hi Stephen,
The meter you have is designed for use on the CB band.? It can be somewhat useful on other bands, but the power output would only be relatively accurate on the 10m band.? Higher frequencies will "peg the meter" and bands lower than 11m will give progressively lower readings.? Also I found in the manual that the switch settings should be "power" and "reverse" in order to take power measurements (seems weird but that's what it said).
