Found ICOM IC-2350H bug. Need Help
 

Have you ever used cross band repeat? I had this happen to mine i used it in crossband repeat all the time one time i left it in crossband repeat and unplugged the power and when i pluugged the radio back in it did exactly as you described. I kept taking it out and putting it in crossband repeat and finally it quit doing it allso i was told that when you hold the two buttons in for crossband repeat that if you push another button in while activating crossband that this could happen whic h if i remember you had to be a contortionist to activate crossband with 2 buttons while holding in something else i dont see how you could hold another button you would need 4 hands hope this helps if not let me know ive been looking for another of these for years great radio
