@vh and friends, you guys are amazing for what you have created here.
I really dont get the "Rough chart of power draw"-Table, especially the 300 MHz. So for 300 MHz it will take 13.98 watts and 2.80 ampere, but I can't find any hubs or whatsoever USB power supplier that goes beyond 2.5 ampere.
So what do I got wrong?
Nothing at all. It requires some "innovative" thinking to supply 3 amps to one of these. Can't be had out of a box (yet).
