  • I have a PGXL on order; when it ships will it have this 'new' version installed?

    Dumb Question - Does it matter which version of the utility I use to download the firmware - the old version or should I download the new utility before updating the amp firmware?

    Thanks - Keith - AC9S

    Not to worry if your new PGXL doesn't ship with the latest firmware it is very easy to upload.

    @AC9S is ia always a best practice to use the latest version of the Power Genius XL Utility to install the latest firmwre.

    Fan and accuracy of the meter is much improved excellent upgrade.

  • Tom OBoyleTom OBoyle Member ✭✭

    I'm not sure what the meter is showing me. Before the upgrade, on SSB using 40 watts of drive, the utility meter would show about 1200 - 1300 watts. The meter is SmartSDR would show closer to 500 watts.

    With new firmware and utility (and after a full power reboot), the utility for 40 watts shows about 500 watts and the history chart shows about 1200 watts..

    What am I missing?

    On the Utility program do you see where it says Meffa in Red?

    Click on that and make in go dim.

    I think you just engaged the Meffa which will control efficiency as function of output power. MEffA is a unique technique that changes the DC voltage level to the PA in a manner to match the envelope of the exciting RF in order to yield the most efficiency.

    Hi Ian -

    I'm pretty sure that is on. I'll try it when I fire back up. Storms all day today.

    Thanks and 73, Tom
