Question: Does it have the 800mhz frequencies?
Document: Scanner radio returned to Amazon for full credit because could not get it working properly. The enclosed CD did not have a manual (at least I could not find it). Therefore could not get radio to work on desired local frequencies.
Very nice scanner was lost figured it would be easy to program with out reading up on it like im used to, but that was so not the case. In order to program my local frequencies I had to research how to do so. Once programmed was up and ready to go. It came with rechargeable batteries to my surprise hold up nicely.
I received a BC346XT today, for Christmas. After much research previously, I decided upon this one in particular and was not disappointed with its feature-set and overall quality. Within less than ten minutes, I had all local NYPD frequencies loaded into the scanner through Freescan [Free PC Software] and was listening in on occurrences around the neighborhood.You must know what you are doing, however.
I want to listen to frequencies---not engage in some tecfhno-marvel that so many cannot figure out. I still have my BC125AT with less power but I love it and it works great. zI will not elaborate here on what I 've done with the thing---because it is too vulgar. The sad truth is, UNIDEN&#8482; seems to have monopolized the scanner market. If they are so irresponsible in marketing this junk it is a sad day for hobbyists.
I have had many handheld scanners over the years and this one tops the list. Sure everyons has been complaining about it being hard to program, well that is not true at all. You can either use the serial cable that comes with it or buy a the Uniden USB-1 cable which is what I have. You can copy and paste frequencies directly from the Radio Reference website. You can get the programming software online called FREESCAN, and it is free and very easy to use.
Even if you do not subscribe to RR it is MUCH easier entering frequencies through the software. You can also customize much of the way it operates through the software and can even setup a connection to allow others to listen to your scanner over the net streaming. Can be nice for if your away from home yet want to keep an ear on what goes on in your area.This is a situation where this scanner does SO MUCH that it would be hard to not have a somewhat complicated owner's manual.
This model uses what is called Dynamic Memory Allocation and it allows you to store more frequencies in a more logical way. It also uses memory more efficiently then conventional scanners. Most scanners have Banks and Channels, this scanner has Systems, Groups, and Channels. Because of this you do not waste any space on the scanner when programming agencies. With that said though, unless you understand it you will pull your hair out programming things.It took me about two hours to get programming of conventional systems into the scanner.
Love the scanner. Good sound quality and great features. Not going to be able to use right out of the box, and programming the scanner is intimidating at first. I was fortunate enough to have a dispatcher on the local police force program my local police department frequencies. After using for a few weeks and reading more online instructions, was able to program local airport and additional public safety frequencies with ease. Overall, great purchase.
Like I say I strongly suggest using the software option even if you plan to enter frequencies one by one yourself, is MUCH easier and you can always go back if you mess up. Simply download everything from the scanner before you begin programming then if you mess up simply upload the original settings back into the scanner.Price was fair, does a lot more than scanners of even a few years ago and aside of digital systems should be useful for a long time to come.
Probably one of the most sensitive scanners I have owned from Uniden and quite affective in picking up long range transmissions - a vast improvement from the BC246T. As per previous models,  manually programming this scanner can be a little difficult so for the novice,  I would recommend investing in a software package that allows the scanner to be interfaced with a computer. Due to USA restrictions,  the 800mHz band falls short of the trunking channels for Australia but this scanner is made for the American market afterall.
Answer: Yes but the typical 800Mhz blocks are in place (no cellular ranges)
