Why not change the antenna before you try a PA? Judging by the link you supplied, it's likely a trace antenna...grafting on either a commercial or homemade high-gain 2.4Ghz antenna might well help. And, no, it's not quite as simple as soldering a PA to a breadboard ;) -m On Tue, Feb 11, 2014 at 1:26 PM, veegee wrote: > Hate to bump, but does anyone have any idea if I'm going in the right > direction with this?
