TX Meter resolution

Is there anyway to adjust the resolution for the TX meter in PowerSDR 2.7.2? I am getting involved in some WSPR activity and would like to be able to adjust/observe output below the default 1 watt scale (1/4, 1/2 watt etc.)

Thanks in advance,

Chuck - KJ6HT

    Just send less signal to the radio and you'll get what you're after.  Turn down the TX from VAC.  I was able to get sub 500mw pretty easy that way.  Not sure if the meter was that accurate though!

    The watt meter in PowerSDR in conjunction with the radio hardware does not have the resolution to accurately measure RF output below a few watts.

    I've got a LP-100a digital vector wattmeter now which measures down to 50mW, so I think I'm good.  :)

    That great. I have three of the wn1 and I am so sold on the wave node runs right with my bird meter. The wn2 reads like the lp and is free standing and or runs the computer program.. I am all about the "visual experience" Glad you have it covered.
