Activating PGXL's MEffa feature using SmartSDR for Mac


The PGXL Windows Utility program has a software switch to turn this feature on and off. I don't see where I can turn this on in SmartSDR for Mac. The MEffa status (red) is displayed on the front panel of the PGXL, but it is not touch sensitive.

Since I'm CW only, I'd like to push the PGXL closer to class C to improve amplifier efficiency and reduce fan noise.

See my Thread under PGXL "Getting MEffA Started" for more info.

Thanks for your insights...

73, Ken

    Appears this is in the PGXL Status panel, "MEffa Enabled" however, doesn't appear to work. No variation in Vdd & Id and MEffa efficiency reported as 0.0%
