I have a Flex 6300 and have been running SSDR 1.6.21 successfully for many months, and am able to drive my amp to full power. I decided to upgrade to SSDR 1.8.3., which went successfully, but now when I use the amp, I get a short burst of full power and then it drops back to almost zero. In TUNE mode it will drive to almost full power, but as soon as I stop tuning and try to operate, it drops back to a very small power. If I don't use the amp, the 6300 seems to put out power normally, but only 75 watts max. The input SWR on the amp is low, but I used the autotuner to make sure.
I subsequently dropped back to SSDR 1.6.21 and everything returned to normal, with full power out of the amp getting about 85 watts max from the 6300. I notice that there was a "fix" which relates to cutting back power on adverse SWR, and I'm wondering if this is causing my problem. I'd like to be able to upgrade.
Anyone else seeing this?
