G'day, looks like the maximum available power setting for SSB really does need cropping to 100W in firmware. Regards, Mike VP8NO | Tap xmit, pwr=120 W, again whistle to the mic, now also 120 W. Now it is | ok until you change the band or power off/on the TRX. Then is starts | again with 80 W. About the same with USB. Also the same with ATU.
