My 396XT has always worked perfectly. This weekend I turned it on and I can no longer receive anything on it. Why in scan mode it will never stop on any frequencies or talkgroups. If I manually enter a known frequency and turn the squelch down all I get is static. This is even the case with WX frequencies. I've tried multiple antennas as well as doing a factory reset on the device and it still has the same results. Does anyone have any suggestions? Thanks!
