"I'm just trying to figure out why none of my radios are working properly. It's not as if I'm new at this; they should work. I'm about ready to pull the trigger on a higher end system. Question is, which one?"

"I've got some of the hobby king radios. They work great as long as you use SMA antennas, the 3DR radios are RP-SMA. I was wondering why I was getting such poor range from the radio when I changed an antenna and used the 3DR radio antenna."
