Dick,Thanks for the tip. My KPA1500 is in the basement on a shelf right under my feet in the shack. I use Remote By Elecraft in the shack to monitor the amp.Took your tip and used the KPA1500 Utility > Operate to get to WMTR Adjust. This made it very easy to make changes and see the results right away.I used the LP-100 as the standard. But the readout does seem to drop off some (15% lower on 6M compared to 160M) as I go higher in frequency compared to the K3 showing 100W. Is it the LP-100 or the K3? Not sure at this stage if I should bother with anything else On the P3 I set the SensorScale to 474.On the KPA1500 The WMTR depended on the band. The range was from 92-99%. The largest readout spread comparing the LP-100, P3 and KPA1500 is now <6% with most bands <3%.This is as accurate as I need to be. I am now a happy camper.I assume I can't attach a spreadsheet. So if anyone wants a copy of my results let me know.73N2TK, Tony
