Running the contest this morning, I noticed the RF Output monitored on a LP-100A Digital Vector Watt meter start decreasing slowly as I was using the FLEX 6500. I was not changing any frequency or mode of operation. However, the RF Output slowly decreased downward a few Watts. Also, I noticed the same RF Output decrease using Digital modes. Retuning the FLEX Auto Tune did not effect the Output. This seems to have started with the new SmartSDR 1.2.1 upgrade..
