This has me truly puzzled....
Last night and tonite during the CQWW RTTY contest, I noticed that my FT-990 is
folding back power only on 40M RTTY. I've watched my watt meter indicate 50,
then 40 then 30 watts out. Switch to CW, 100 W out.
Any other band is fine...100W out on RTTY (or any other mode for that matter).
The rig is running cool to the touch, the fan is kicking in appropriately... so
I assume heat is not an issue.
Operating time seems to be a factor....in other words, prior to switching to 40
I had been on 20 for about an hour or so. This morning after the rig had
"rested" overnight, I had 100W out on 40.
Thoughts??
Thanks,
Frank, W1NK
