Excellent chart!! One suggestion is to maybe add a last column with a general price range for each unit.Looks like it jumped up to $460, besides one sketch seller.
By the way, for anyone considering a new digital scanner, I made a comparison chart on my website: Digital Radio Product Recommendations
I don't think I've shared it on here yet.
The TRX 1 & TRX 2 have the most green checkmarks, meaning, overall, it's your best bet for receiving the most types of digital radio.
Many Uniden models support GPS auto-programming, going back at least to the X96xt series. Possibly further, I'm not that familiar, not owning any of them. I priced the GPS puck awhile back, I want to say it was on the order of $70-$80 but I can't recall at the moment. I do know that a lot of Uniden users really like this function, especially with the HP-1/2 series.GPS is a good one! Is it just the 536, or do the others do it too? And about how much money for a GPS dongle that works? I'll probably add that to the list sometime soon.
