KPA1500 duty cycle

RTTY contesting has a much higher duty cycle, especially when using a
single radio and no one is answering your CQs.

The FT8 parameters were tweaked slightly during the beta phase prior to
the release of WSJT-X 1.8.0, and the TX time was reduced to 12.64 sec,
so the duty cycle is now about 42%.

And you can affect duty cycle by adjusting the cw repetition rate. If it gets too hot increase the delay.

The KPA1500 can handle 1500W RTTY contest operation with no problem. Same for CW.

(One of our Field Testers is W0YK. See his review on eHam.)
