Well-protected is not quite the same thing as continuous service or maximum linearity. The KX3 is fine at 10-12W for CW or SSB, but people generally run it at 3-5W for FM or digital modes.
Of course, when you need the juice, you need it, regardless of mode. wunder K6WRU On Feb 21, 2014, at 11:04 PM, Jim Brown <[email protected]> wrote: > On 2/21/2014 7:43 PM, WA7SPY wrote: >> I was looking at the operating manual online and did not see any recommended >> power setting for operating the amp with digital modes. > > Elecraft output stages are very well protected.
