Today I got all excited and thought about seeing what kind of range of usable range i could muster by connecting a small amp to the DMR hotspot and connecting it to the outdoors antenna. I was putting about 0.5w out into a slim jim about 3m off the ground. I could still hear the kerchunkers about 1km away. Nothing stellar but you really could not expect to much giving the setup.
So after that I got all excited and connected the Hackrf to the same little amp and again to the outdoor antenna and fired it up in FM CW beacon mode and got an ultimate range of about 3Km. Again nothing stellar but considering everything, not to bad either.
So the moral of the story here is I really need to get the antenna much higher into the air if I want to be able to turn this into something a little more usable without resorting to much higher power.
