there is no such thing as an incorrect alpha tag, an alpha tag is what each individual wants it to be, that's my point, if you are changing an incorrect frequency, or PL tone, fine, change the alpha tag as well if it pleases you. I've done that myself, but if the only change you are making is JUST THE ALPHA TAG, it gets annoying. you have to pull out your old paperwork or go through the frequencies on your scanner only to find out nothing changed.
OK, I admit, in the grander scheme of things, this isn't that big of a deal, but after working 60 hours a week, every little inconvenience becomes a pain, sorry, I'll take a nap, lol.
