After downloading 1.2.1765 on the Flex 6500 I noticed the power output power was about half of the output on download 1.2.125. I went back and forth several times and the results the same. What are your thoughts.
Try resetting your persistence database. Power off the FLEX-6500 using the front panel power button. Momentarily remove DC power from the radio. Press and hold the OK button on the front console. Press and release the power button. On the radio console you will see an indication that the radio is being reset to factory defaults. Continue holding the OK button until the console display counts down to 0 and the power LED is illuminated white. Allow the radio to continue powering up normally.
Then put the radio into SSB mode and click the TUNE button and move the RF Power slider up to 100. This should put out a nominal 100W into a dummy load.
