Hi everybody
I would like to buy a radioscanner for hear airband frequency (118-136 MHz).
I have two options: Whistler Ws1025 and Uniden BC365CRS.
I download manual in pdf each one and i noted one specification data: Sensitivity 12dB SNAD.

Which is better (more or less?):
  • Whistler Ws1025 with 1.0 uV in airband frequency
  • BC365CRS with 0.4 uV in airband frequency

Thanks in advance.

The lower number is better sensitivity, assuming the measurement method for both is 12 dB SINAD.
True, though in pratice they‘re not likely to notice any difference. I live far from the transmitting sites of the major air centers so I get the ground side weakly from long away and I can still pull them in with less sensitivpity than that using a 2m rooftop HAME antenna. Fair weather aviation receiving in the area of the transmitters will likely be fine on any radio, the main issue is selectivity when there’s strong FM broadcast or 2m HAME/Commercial repeaters in the same town. I sometimes catch images of both the Skywarn and Sheriff office repeaters.

Looks like imonitor beat me to it. If you are not locked into those two base models, then I suggest considering the Uniden BCT125AT. I have one dedicated to airband reception and it works very well. Excellent sensitivity. The price is about the same as those other two models you have in mind.

Receiving in AM mode have much to do with how the AGC control are designed in the scanner. The optimum are if strong signals sound as loud as weak signals. Sadly many scanners fail and strong signals sounds much louder due to a bad working AGC. Best are probably to look at reviews from actual users of the different scanners you are thinking of buying.

Already i have Uniden BC125AT, is portable and i use in travels, and now i am looking for desktop scanner with no need batteries, it be possible to attach to pc to internet for transmit to an icecast server or LiveATC and both models like to me, but i need to select one. Which you recommend me with your experience?

Are you limited to those two? If not, check out Uniden's BCT15X. That would be my choice. If you keep an eye on prices you can pick one up for as little as $169. Used go for a little as $125. It has advanced capabilities far beyond your other two choices!

Hi iMONITOR thanks for your suggestion, really i am limited in money, and import this model to Mexico, it gets expensive.

The BC125AT can be powered off house (mains) power using the USB cable that comes with it and a "power block." That's how I am using my BC125AT.

Here's the cable plugged into the side of the BC125AT.

And here's the other end of the cable plugged into a power block, which is plugged into a power bar.

I can unplug it and run it off batteries when necessary.

I just bought the BC-125AT and it has been very good. I have had many scanners over the years, and as far as portables go this is the best I have had, for both sensitivity and the ease of powering when at your desk, as described by KB2GOM. As for base I currently use the Radio Shack PRO-2048. Doesnt have the alpha tags but I know my local frequencies so no real need. I also use other Bearcat scanners, ones also used for 700 MHz trunktracking and they are good as well, but I feel not quite as good as the receivers that don't have 700 or 800 coverage.

I use these.

The cable is power only, so it's more flexible than a 4 wire data cable. It also has a 90deg head so the cable lies against the body of the unit, and it's a mag disconnect - less likliehood of the radio taking a tumble & damaging a USB connector.
