WM-2 operation

I am having trouble understanding the operation of my WM-2. When I select the range manually, all is well and the meter functions as it should. However, if "Auto" is selected, the meter seems to show a high peak reading upon initial keying, i.e. with rig set to approx 100W output, the meter will show a peak of about 150-160 W. SWR as measured by the meter is < 1.5:1. ALso, when "auto" is selected, the 20W LED also lights up. None of my other meters behave like this, and indeed, the WM-2 doesn't either when in "non-auto" mode.

Thanks for any help.

Re: WM-2 operation

It sounds like your W2 is set to display PEP power. Use the 'Command Tester' in the W2 Utility to send the "M" command to the W2. This will toggle between PEP and AVG power. There will be software available soon to easily set all of the W2's parameters.

Re: WM-2 operation

Thanks for explaining this since my W2 is acting the same way. I will use
the W2 utility to change to AVG power.
