[Elecraft] Digital mode power handling for KAT3

[Ken WA8JXM]

Not just the tuner,  the K3 is not rated for full power on 100% duty cycle
modes.  Just like it's not rated or 100% key down CW.  But realize that
many of the modes are half transmit and half listen.

Different digital modes have different duty cycles.

>From the W1HKJ.com website:
100% duty cycle: Olivia, MFSK,RTTY
80%: BPSK, MT63
44%  CW
22%:FieldHell

There are more modes on Dave's website, but those are some of the
major ones.  IDK if Joe Taylor has similar information on his website for
the modes he supports.   It loioks like his modes may require full duty
cycle.
