1W out with FLEX-1500 after update

Hi all,

I update PowerSDR KE9NS v2.8.0 from build 80 to 113 and my FLEX-1500 is running 1W max instead of 5W. I don't know where is a problem...

Any idea?

    Confirm that the drive and the tune is set at 100. The default tune drive sets at 10. I am presuming you are using the same power meter that you used before the upgrade.

    Rich, I own a Flex-1500, check your antenna selection, it may be set for a transverter. Just a thought.

    Are you selecting Tune button?  Select Tune,  then while the "Tun"   is selected,  then move the " Drive "  control to 100 % .   There is a normal operation and then a Tune selection WHILE selected only ..   The default is 10% not 100% in Tune.

    I tested my 1500 running v2.8.0.113 with no issues (5 watts out to a dummy load).
    As a test, do a  Setup->Factory Defaults (this will make a backup of your current database to you desktop first). Or a SHIFT+CTRL+C and do a restore calibration from the EEPROM to your database and see if that fixes it? (with Tune reset back to 100)
