New user but had my UV5R working great. Until I started Chirp and adjusted some freqs that worked great. However I noticed it was very quiet. After checking all works good Except no speaker volume.Many years ago I was a 2 way tech for Motorola and learned that when u plug in an ear bud and hear radio great but remove earphone nothing, it is likely a bad earphone jack. PLEASE TELL ME IT IS SOMETHING ELSE!!
