[Elecraft] Suggested Enhancement for KPA-1500

[Mike Cizek W0VTT]

Hello Fred,

I use the programmable function keys for this:

PF1=  ^fc2;   
PF2=  ^fc0;

Fan speed 2 is usually enough to keep the heatsink temp below 70C.

I have a KPA-1500 amp in our station, and I use it on a daily basis in a remote configuration to operate our station. Fan noise is not an issue here because we are not in the same location as the amplifier. Further, we do mostly digital modes (MSK144, FT8, Q65, etc.) which are high duty cycle. I mostly use the remote app to force the fan speed to a higher level than the factory fan curve to help keep the amp cool. It would be nice if the KPA-1500 FW had a few fan profiles to choose from to help keep the amp cool when running high duty cycle modes. This way, operators such as myself who do a lot of high-duty cycle modes could keep their KPA-1500’s cooler and extend the life of the amplifier.

Best and 73,
