[Elecraft] Piggy back KPA 1500 onto KPA 100

[Karl W Hubbard]

This question may have  been answered in the  past.
I have a KX3 and a  KPA100, both with ATUs. Can I power up my TX via addition of a KPA1500, assuming I upgrade my antenna (Buckmaster 300watt OCFD 8 bander)  to the  3000 watt version ? If feasible without risk of blowing up anything, and  assuming the KPA 1500 also has a built-in autotuner, at what stage should auto tuner control be established?


Thanks, and 73’s
