Thanks to Gordan and Larry. I do not run the station hot. Max temp seen has been 73 degrees centigrade (auto shut down is at 85 C). Most of the time max temp is 67 C. I do have the same number of ALC bars on 80 meters as on 15 meters. Increasing the output from my sound card just made the output totally stable at 40 W instead of varying between 30 and 40 W. So all I got was overloading. Mic gain is up at 50. By the way RTTY is down about half of the power of that on PSK 31. To the best of my knowledge PSK31 and RTTY has been up at 85 W on 80 meters until two weeks ago. Just now I noticed that for the last second or so of the transmission it seems like I have full output also on 80 meters. BUT it is not a question of warming up as the full output is seen only for the last second whether I am transmitting for two seconds or for about twenty seconds.

Situation: Starting on 15 meters running RTTY or PSK31 with an output of about 85 W. Using Ham Radio Deluxe switching to 80 meters, also switching antenna. The output falls down to about 40 W. Changing to CW (still 80 meters, same antenna) I get 85 W again like on 15 meters. Which settting have I overlooked that brings my output down?
