My 245XLT finally died the other day. My wife misses it and wants me to buy a new one. She has a few requests. She wants alpha tagging so she can see who she is listening to, can't make up her mind base, mobile or portable, loves listening to the police (800) and fire (VHF). Is driving me nuts trying to figure out what the difference between TrunkTracker III and IV. Someone who knows wayyyy more than I do help point me in the right direction. Oh, and she would like it to have a battery backup for when we lose power. Oh, and she likes Unidens. (I don't care either way.) And I forgot to mention that I would like to be able to catch Skywarn during the stormy months.
