The BC125AT is lightweight, about the size of the BC246T, and should fit in a pocket great for all RF activities. It has great display for visual, it's easy to read, but the red/orange back-light is still going to be hard to see in direct sunlight. It's RF sensitive, but I suspect prone to intermod from stronger signals (especially RF generators like PC's).
I picked up mil-air activity really quick. VHF Civil Air is sensitive also. Not much activity on Railroad so far, but I'll be listening.
I find it is a real KISS radio. Not much to do for setup unless you want to label everything, but you can do that with the BC125AT_SS software and the ARC125 (in the process of beta). The SS software is great to get you started, but your going to want to import from the Radioreference database, especially the Nationwide frequency data.
The software is not included, however it is a full program free download on the Uniden Twiki site. Most people in this computer age are now able to access the web, but there may be some folks that would not even need the software.
The Service search and Close Call Do Not Disturb is going to be great at the next Air Show. I'm going to take it with me to AZ this week and subject it to some high RF areas and see what happens.
DCS/CTCSS search is as always, is fast I had no trouble finding a local CTCSS and DCS code that I already had known. Ham stations sound 5/9, with no hum or background except for the usual rag-chewing.
I think race/air show fans are going to need a quality headset like the RaceScan set I have. Some may even want a built in audio amp. The volume in the home setting is quite loud on the higher end, but as usual for this price point, don't expect exceptional volume output from the small speaker. It does sound good with my Etymotic MC5 set of earbud headphones.
Squelch is a mixed bag. You need it a little higher for the VHF air due to the AM modulation setting, but it works well at a low number setting for general coverage. A setting of 3 or 4 on the squelch is a good balance. To aacess the squelch you need to hit the function and tap the scroll control, then spin left for down and right for up to set. Volume is just as easy from just a tap on the scroll control.
Another thing to expect is noise (QRM), the radio IS sensitive, so if your near an RF source, expect many frequencies to be hearing false signals.
I'm not sure about the signal strength calibration, but I read full-scale five bars on many of the local stations. DX stations are low volume readable at one or two bars.
The two included batteries are chargeable via the USB port. Keep in mind you'll need a AC to USB adapter that is not included, or use the computer USB port. However, as usual I recommend an external charger for your batteries.
All in all, a great looking radio that I'm sure will be a hit for activity scanning.
Hopefully ScannerMaster will have a Nylon or Leather case for it soon.
I give the BC125AT a 4 ot of 5 for out of the box operation. Let's see how it holds up in real RF areas. :twisted:
