Operating my Flex-6600 on 80 m SSB (90W) the PA temperature start to increase and when reaching 44-47 degress C the PTT(MOX) releases. After approx. 15-30 s I can activate PTT again. Using SSDR 2.5.1. The same issue with SSDR 2.6.1. The large fan does not increase
the speed when the PTT releases.

I took some temperature readings during the WAE RTTY contest. I was calling CQ every 5 seconds at 100 watts. I measured air temps of 57C coming out of the back panel right under the power connector with no operational issues. I did not note the PA temps but I would think they were pretty high. The cooling fan was running at full speed ! I am using Flex 6600M with SSDR 2.5.1
I suspect your fan controller is not ramping up the fan speed when the PA gets warm ? Please open a ticket with Flex support.
