I have also done the update, to 3.0.1 and am now having HUGE P25 issues ( and yes, i have done EVERYTHING listed above, reloaded both the update and programming blah blah blah) setup is IDENTICAL as before, same antenna, same location, same 60Hz power source, and now my VHF P25 system i listen too has has hugeeee errors....in fact when using Freescan's control software, it shows a reception level (mid 700's) that is identical to pre-update, so the reception hasnt gotten any worse, i guess i am going to have to hunt down a V2 as well and switch back, something is definitly buggy about the update.
PS: the difference was noticable right away, i was listening to the system right before i updated and listened to the system right after and as soon as it loaded it sounded like my bc250d with all that digitized voice crap
