What is the maximum safe operating power out for AFSK RTTY using
the KPA100
in the EC2 case? The manual says 40 Watts for BPSK, and 25 Watts MFSK.
My KPA100 is in the K2 case, but I'll relate my experience.
I've run my K2/100 very hard in contests, SSB, CW and RTTY. I can run
100 watts SSB or CW, no problem. CW ends up being a lot hotter than SSB.
If I run 40 watt RTTY, the heat sink will get even hotter than the
hottest on CW. I would recommend 25-30 watts only.
If you add a supplemental cooling fan to the heat sink, you can run
50 watts or so.
