Very very small is the answer and smaller at lower frequencies.
Indeed, and thus about 73500 times higher at 10GHz than at 136kHz ...
Andy will not be happy ;-)

BTW: Planck constant is 6.626*10exp-34 Js thus absolute QRP is about 10exp-30 W at 136kHz and about 7*10exp-24 W at 10 GHz.
If anyone can copy your claimed "absolute QRP" signal there is a 99.99999.. % chance that you are cheating, if you are copied by 2 stations at the same time is is 100% sure.
