the last couple of times I've tried to blind scan IA6 the receiver (fortec lifetime ultra) has just hung after a bit. last night, for instance, it found 41 transponders then seemed to get stuck for several hours. the little animation was still going on the screen and i was able to exit, but i have not been able to complete a blind scan on IA6 recently. and it seems the transponder that it hangs on is random. is my receiver going bad, or does anyone have any other ideas?
