Tom, Yes, you can use the RF probe. It *should* be OK up to a max of 20 watts measuring across a 50 ohm dummy load. The 1N34A diode is rated at 45 volts peak reverse voltage, so if you exceed 30 volts RMS (the RF Probe reads in RMS volts), you are nearing the limit.
The accuracy of your measurement depends on the accuracy of your dummy load. It would be wise to check it with an antenna analyzer at the frequency you will be using for calibration (40 meters is preferred) 73, Don W3FPR Tom Campie wrote: > Hey guys, I'm going to finish my KAT2 tonight and I need to calibrate the > power and all that stuff.
