I finally figured it out (RTTY)

[Kevin Murphy]

Hi,
  I was looking at the RTTY page of Steve, W2MY/5
and came across his Cat page

Well, our  cat Bandit, and I thought it was terrific.

Hi all,
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.

TU,
Steve, W2MY/5

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.
