I starting to use my K2/100 in two 100% key-down modes, JT-65 and PSK-31. What should I be keeping in mind in protecting the output stage for the K2 and for the KPA100?
For JT-65, since it is a QRP mode, I'm running at about 5 watts, and transmissions are limited to about 45 seconds. So, I'm hoping that K2's output transistors will not be stressed in this mode. But, how about PSK-31? I'd like to run about 20 watts and each transmission could easily be 3 or so minutes. I don't know at what output power the base K2 runs when the KPA100 kicks in (i.e., at above 10 watts). I assume that normally the KPA100 will be loafing at 20 watts, but I'm not sure the impact of 100% key down on its output stage. I'd appreciate any guidance in keeping the K2/100 "safe" in these modes.
