For the past few years I've been running a very nice UBC125XLT, no problems with it at all!! But until recently (2 months ago), I just fancied upgrading and having a play, so I decided to go with an AOR AR8200 MK3 300mHz all mode scanner. The first few days it scared me to death lol, a fantastic piece of kit BUT just comes across out of the box, screaming at you - IF YOU ARE LEARNING ME, IM GOING TO MAKE YOU SWEAT!!!!! First few days, very slow trying to grasp it, but after a couple months, I feel more at home with it. With regards to the power supply!! I emailed AOR JP asking about the batteries for it. I just felt charging the 1800 NIMH supplied batteries for a 20-22hour charge through the handset was a bit much (advised in manual), plus the AOR didn't seem to last very long after the charge at all (4 hrs total'ish). I asked if I could upgrade the batteries to a higher capacity, they got back to me saying yes I could upgrade but advised to charge the batteries through an external charger. So now I use 2400,2500NIMH Duracell rechargeable batteries and charge them through a decent Duracell charger. The AOR with full power now seems to last for ages. Seems to run better too with a decent power charge. As this AOR is a handset you need to study to learn its operations, its made me look deeper into the scanning world, it just draws you into it, which makes it more exciting.
So because of this, I looked into scanning digital as well. I did look at the Whistler?, but Uniden released the UBCD3600XLT and it did sound good, so purchased it. Absolutely love it, again the first couple days getting used to it was a pain. I feel I've found my way around the Uniden far easier than using the AOR, general use, programming analog and digital modes, general set up etc. As for the Sentinel software installation on my Mac Pro running Sierra was a little tricky as its designed for Windows. You could try a program from the net called Wine if you wish to try it. For added support, I've played it safe and installed Parallels from the App Store (in app purchase required), It allows you to run Windows 10 on the Mac. Now installed, it supports and runs the Uniden perfectly, a little costly but very effective.
I have also been looking into the Uniden customer support for European/UK customers of the Uniden UBCD3600XLT. Im in the understanding that our USA brothers who have the 436HP version can register their handset to the website and can purchase their updates via Uniden. The European 3600XLT versions are run differently, we don't need to register them, when Uniden release updates for Europe, we will get notified through the Sentinel installed on our PC's, and will update when connected. Uniden will release updates to improve functions and add extra FEATURES
CANT WAIT!!! There is a leather case being released in a few weeks for the UBCD3600XLT. European/UK customers who buy the mighty 3600/or a new Uniden don't need to write to Uniden USA/AU or JP Corporate, we do have a European contact!! We can speak to our local retailer OR we can write to the main European contact for Uniden, they are http://www.avera.eu
They are very helpful and are willing to answer any questions you may have. Anyway I'll stop babbling on lol. If you have any questions on the 3600 setup etc, I'm happy to answer any Q's, been studying it like mad.
