Hello.
accidentally, I connected the wrong antenna to my TS-590SG.
Since then, the TX power output is proportional the the band!!! The higher the frequency, so is the power, and the best is on the 10 meter band and its only 10 watts!!! ATU is disconnected.
SWR is good.
The power of the 6 meters band is OK.
Full Reset didn't solve the problem.
Power Supply is good too.
