I bought a used antenna tracker and Tiny Telemetry about a month ago and it worked fine until a week ago. The first flight of the day I couldn't get it to work right. I was getting bad packets but no good ones. On the second and all other flights that day it worked fine. A couple of days ago I couldn't get it to work at all. Sometimes I could hear the audio coming out of it and sometimes nothing. I also noticed sometimes the LED wouldn't blink when I tuned on the plane. Yesterday I was reading somewhere that the firmware form the EZOSD would work with it. I thought what the heck, it's worth a shot. I figured it would get an error or something if it wasn't compatible. I uploaded it with ImmersionRCTools so I figured everything was okay. Well, it wasn't. Now I don't get a flashing LED when powered up and my laptop won't even detect it when I plug it in to the USB port. Is there any hope for this Tiny Telemetry unit? I went ahead and ordered another one so I would have one for this weekend. I figure I can use this one on another plane if I can get it fixed.
