[Elecraft] KPA1500 wattmeter adjustment

[tony.kaz at verizon.net]

If I measure the power out on my K3 (set to 100W), P3, LP-100 and KPA1500 (power on but in standby), they all read quite close on 10-160M into a dummy load. On 6M the P3 reads 16% higher than the other three. If I use 20W drive from the K3 and put the KPA1500 in operate mode, the P3 and LP-100 read quite close into a dummy load. But the KPA1500 reads about 6-11% higher on 6-160M.The readings are close enough not to be concerned. Looking at the KPA1500 manual there are commands to adjust the wattmeter readouts by band.  I tried commands in the KPA1500 utility Command Tester (^RV;) as an example, but nothing happened. Checked the Port tab to make sure the utility is connected to the amp.What am I doing wrong? Can you do what I am trying tp do from the Command Tester.TnxN2TK, Tony
