Just completed mods to U3s and mistakenly applied 12v supply to 5 v bus. Pinned the ammeter, hard.
Replaced synthesizer and eprom. ?QLG1 GPS not flashing.
Only thing not replaced is the display board. ?Shows ? most signs of life but won't tx. ?
Any hope of recovery? ?What components likely damaged? ?Maybe start with a new U3s?
Another less dangerous hobby perhaps?
Thanks,
Tom ?KJ6MKI
