1、68 MONITORING TIMES June 2009 B ob Grove said the BCD396T handheld, “is the most advanced scanner ever designed.” And when you looked at all the scanning capability built into that small package, no truer words were ever spoken. Now Uniden has released an updated version of the venerable 396 and it

2、made a great scanner into a super scanner. Case, Controls and the Antenna The BCD396XT is a direct descendant of the popular BC396T handheld scanner. Many of the primary features found in the earlier unit apply to this new handheld. The 396 case measures 2.40 (W) x 1.22 (D) x 5.35 (H) inches and wei

3、ghs in at 9.6 ounces with batteries, and about four ounces without. There is a multi-color backlight system for the 1-5/16 by 13/16-inch liquid crystal display. There are four user-selectable menu options for display backlighting: backlight on for 10 or 30 seconds (push button select- able), squelch

4、 (backlight illuminates when the squelch opens and stays on for five seconds), keypress (backlight turns on when any key is pressed then stays on for 10 seconds), and infinite (backlight turns on when you press the multi-function power on/off key, then stays on until you press it again). The screen

5、backlight can be tied to a channel alert, so even though dark blue might not be good for normal viewing, it is useful to indicate a channel alert (the display briefly changes to the alert color, then reverts to the normal selected blacklight color after the alert). Available LCD backlight colors inc

6、lude red, blue, magenta, green, white, yellow and cyan. The keyboard backlight is not tied to the LCD backlight color selection; it is always white. There is only one knob (scroll type) on the top of the unit that controls a variety of the scanners functions depending on other controls being depress

7、ed. The multi-function scroll knob is used to set volume and squelch levels, adjust menu settings, enter text, change channels in the hold mode, resume scanning, and change display screens. There are two push buttons on the side of the 396XT that perform the same operations as the buttons on the sid

8、e of the 396T function and menu selections. These controls are the heart of the scanners menu, display, and ad- ditional control functions in conjunction with keys on the front of the scanner. The 396XT uses a flexible antenna with an SMA connector. They have included a BNC to SMA adapter for additi

9、onal antenna connection options. Antenna jack impedance is 50 ohms. Its what is under the hood that counts. Given all of the recent concern over rebanding in the 800 MHz band, you wont have a problem with the 396XT. The memory unit can be re-flashed via your computer so it The Best Just Got Better U

20、e new 700 MHz public safety band, 800 MHz, and 900 MHz bands can be programmed. This includes trunk systems now being installed by the Department of Defense in the new 380-399.9 MHz LMR sub-band. The scanner can also scan both con- ventional and trunked systems at the same time. In addition, the 396

21、XT can monitor certain trunk systems using control channel trunking. If the scanner is set to scan trunk frequencies, the user can track the trunk system using only control channel data. You do not have to program all of the systems voice channel frequencies into memory in this mode as long as all p

22、ossible control channels have been programmed into the scanner. So What Has Been Added? So is it worth upgrading from your BCD396T to a new BCD396XT? With the new feature set listed below, the answer to that ques- tion is a resounding Yes! There are a lot of new features incorporated into the 396XT,

23、 a lot of them based on feedback from owners of the 396T scanner. The ability to manually select a specific programmed channel in the older Uniden dy- namic allocation memory scanners was one of the biggest complaints by the old channel and bank scanner crowd. With this new system/channel number tag

24、ging feature in the 396XT, you now have rapid access to a specific system or channel. More information is available on this at http:/ NumberTags Intermediate Frequency Exchange changes the IF used for a selected scanner frequency to help avoid image and other mixer-product inter- ference on that fre

25、quency. A new band scope provides a graphic rep- resentation of signal activity on the display. You can get more information on this feature at http:/ BandScopeMode Quick-Access Search Keys This scanner has three search keys that you can assign to a special search range. More information is avail- a

26、ble at UnidenMan4/SearchKeys This new scanner has support for P25 conventional channel monitoring that includes NAC and talk group ID user differentiation (P25 One-Frequency Trunk). Another new feature is Control Channel Data Output that permits the analysis of control channel data without the need

27、to perform inva- sive modifications to the scanner. You can now use software programs such as Unitrunker and Pro96Com to analyze or monitor trunk radio systems. Private Systems lets you flag a system so that it cannot be read out of the scanner or modi- fied. There is also a Key Safe mode that, once

28、 set, lets you hand the scanner to a novice user without fear that they will modify the program- ming in the unit. Other new features include: NAC decoding of all P25 signals Ability to fl ag a channel as digital, analog or all Multi-site system support like its 996T cousin Close call temporary stor

Overall Rating and Final Thoughts There is a lot to like about this handheld scanner. Even though the audio amplifier system supplies 90 mW less

33、audio, Uniden has done some re-engineering and the audio is definitely an improvement over the 396T. The 396T had a hissy and muddled sound, but I did not note that in the side by side test I conducted. APCO25 digital audio was also a major complaint and Uniden seems to have put those problems behin

34、d them as well. The unit performed well on the four trunk/conventional systems on which I tested the unit. I did not hear any motorboating, and when compared with the 396T, I did note a definite reduction in watery audio. I also saw better rates and fewer drop outs on the 396XT. The multi-colored ba

35、cklight of the display is a neat feature, but, when using lower contrast settings, on most of the colors the display is hard to read. I would dump that lousy blue color in favor of a bright orange color as used on the BC-330 or BC-246. There is no UASD programming software as of presstime, and witho

36、ut it, programming this scanner can be laborious. Based on our conversations with Uniden, UASD software will be available soon. In the meantime, I have published in our specifications table a couple of software packages that are available right now, including FreeScan. FreeScan works okay with the 3

37、96XT I tested, but I did get some timeouts from time to time. On the VHF High bands and above, the re- ceive sensitivity on our test unit was definitely better than the 396T and 996T units against which it was tested. No major intermodulation issues were noted at our rural location. MT FIRST LOOK RA

You do get a CD-ROM with the user manual and additional material on it, but you will have to have a computer in order to use it. There is an up-to-date manual onlin

40、e and changes are made to it as they are discovered by the Uniden team, but that also requires a computer and internet connection in order to use it. I really think some sort of printed manual with at least the basics required to program the radio is important for users who do not have computer capa

41、bility or access to one when they need to program the radio. Are you listening in Fort Worth? As mentioned above, I still dont like the backlight colors. Fortunately there are more options on this unit than the cobalt blue colored screen on the 396T. The white color wasnt too bad, but it was a littl

42、e hard on the eyes over time. While not a Uniden problem, I could not get the 396XT to work with Unitrunker, even though that radio is listed as being supported. I understand that others have had the same problem. Bottom line Uniden has released yet another new scanner with cutting edge technol- ogy

43、. No one in the scanner marketplace right now offers a scanner in handheld or base/ mobile model that has the frequency coverage or the listening capability that this unit has. The new Uniden BCD396XT handheld is truly another marvel of modern scanning technology. The best just got a quantum leap be
