Uniden

New Uniden Bearcat BCD160DN & BCD260DN

  • To be released early 2024. See more information on Uniden website BCD160DN BCD260DN

My Issues with buying this "new" scanner:" Yes, it does NXDN and DMR Conventional. TRUNKING and P25 NOT INCLUDED. NOT AVAILABLE.

WHAT they are NOT telling you (from what I have gathered): Some of this stuff matters to more advanced users, others may not care

  • IT WILL display the COLOR CODE or RAN (and apparently Area Code) (and can be programmed for a specific code)
  • WILL NOT DISPLAY TALKGROUP NUMBERS. So you won't know what talkgroup is actually transmitting. You won't be able to only listen to a particular talkgroup and not another one.
  • WILL NOT DISPLAY UID/RIDs (Radio ID numbers). So you can't differentiate those talking or name the radios in the software

There is not enough room on the screen for this, plus with this type of scanner (Banks), I don't think it could work with a list of RIDs.

  • WILL NOT have "1 FREQUENCY DMR" type "UNIDEN TRUNKING" programming. You just enter in a frequency and it decodes the audio, but is not giving you the information (if you want, like, or are used to it in the previous models). This does not have the architecture, this is a BANK memory. (hardware driven radio, not software)
    • According to the Owner's Manual, it will show if the frequency is CAP, CON, DT3, DMR, IDS, NX4, NX8, XPT, P25/DAT (which will be skipped)

We don't know what the future of Rail Scanning is going to be like when it moves to NXDN. There may or may not be any talkgroups in use, but I'm sure there will be Radio IDs. (some conventional NXDN uses talkgroups, but a majority just use "Group Call") 2 different railroads can use 2 different RAN codes. Are you able to program if for only 1 code (so you don't have to hear the other one?)

All I'm trying to do, it help those that just want to go out and buy one immediately without thinking about it's full capabilities.

I have not found a manual PDF yet. BCD160D Manual PDF BCD260DN Manual PDF (It appears that the 260DN manual for English may have been uploaded as the French version)

All the photos that I've see are very generic. The programming software really doesn't show a lot either.

Aviation

AM Aviation Frequencies All frequencies here use AM (emission designator 6K00A3E).

  • 121.5 Emergency & Distress
  • 123.1 Search and Rescue (SAR)
  • 122.9 Search and Rescue (SAR) Secondary and Training

Emergency Position-Indicating Radio Beacons (EPIRB), Emergency Locator Transmitters (ELTs), and Personal Locator Beacons (PLBs) transmitters operate on 406.0 to 406.10 MHz, and some have low power 121.5 MHz homing beacons. Older ELTs use 121.5 MHz, which is also the civil aviation voice emergency frequency, and are still in widespread use. Aviation Notes:

  • Communications with aircraft in the public safety environment is complex and carries additional risks over traditional land mobile radio. Communications occur in both AM and FM modes. AM Communications are typically for pilot to pilot, pilot to tower, pilot to ARTCC, etc. It is less frequently used for tactical Air-to-Ground communications. Extreme caution must be taken with AM Airband frequencies, these are the least desirable choice for Air-to-Ground communication. While not necessarily prohibited, it presents much greater risks to aviation assets than using a discrete Public Safety FM channel.
  • Most Air-to-Ground (A/G) communications occur on FM in the traditional FM VHF, UHF, 700 and 800 MHz bands. Careful coordination of these channels is critical. Frequencies coordinated specifically for that use should be employed. Many jurisdictions have set aside or in some cases licensed specific Air to Ground FM channels in most of the bands. These allow the users to communicate with air assets in a safer environment. A concern with any airborne transmitter is the extended range of the transmission when airborne. It is often the case that an aircraft can broadcast substantially further than the license limitations of the local licensee or user, possibly resulting in unintended interference to other agencies and to the aircraft itself. When multiple aircraft operate in the same theatre of operations, frequency deconfliction and tasking coordination will prevent confusion

25 Cities Project Federal Interoperability Channels

  • These are VHF channels that use FBI fixed infrastructure to provide wide area coverage for federal, state, and local public safety users. There are currently 56 channels, overseen by 31 FBI Field Offices. The primary use of the channels is for interoperable communications during both pre-planned and emergency events. The channels may also be available for internal agency communications. All pre-planned use must be coordinated with the local FBI Telecommunications Manager. All federal, state, and local public safety agencies are encouraged to program the 25 Cities frequencies into their land

mobile radio subscriber devices. Most 25 Cities VHF channels are accessible by non-VHF users via permanent or ad hoc patching capabilities provided to many agencies as part of the 25 Cities Project. Please note that in certain cities, the channels use the VHF Law Enforcement (LE) Federal Interoperability frequencies: Baltimore (BA LE 3); Boston (BS LE 4); Charlotte (CE LE 4); Honolulu (HNL LE 2, HNL LE 3, HNL LE 4, HNL LE 5); Kansas City (KC FIOLE2); Milwaukee (MW LE 4, MW LE3 GB, MW LE2 MA); Newark (NK FIO LE 2); Richmond (RH LE4); San Juan/Puerto Rico (SJ LE 2 ME, SJ LE 3 YQ, SJ LE 4 CS, SJ LE 5 CP, and SJ LE 2 STT), and Washington, D.C.

FirstNet LTE

The First Responder Network Authority (FirstNet) was created on February 22, 2012, under the Middle Class Tax Relief and Job Creation Act. FirstNet is an independent authority within the U.S. Department of Commerce's National Telecommunications and Information Administration. It is governed by a 15-member Board consisting of the Attorney General of the United States, the Secretary of Homeland Security, the Director of the Office of Management and Budget, and 12 members appointed by the Secretary of Commerce. The FirstNet Board is composed of representatives from public safety; local, state and federal government; and the wireless industry. These dedicated individuals bring their expertise, experience and commitment to serving public safety and meeting the FirstNet mission.

In 2017 Nextcom launched its FLEX branded 4G LTE two way radio service that provides instant, always-on communications between teams no matter where they are in the USA and Canada with no roaming fees, no licensing, no long distance and no overage charges. FLEX truly redefines "wide-area communications."

CDCSS (DPL) Tones
CTCSS (PL) Tones

PL Codes (CTCSS), DPL Codes (CDCSS), NAC Codes

The Continuous Tone Coded Squelch System, commonly referred to as CTCSS, has been in used in the land mobile radio arena from the late 1960’s. It is known by a number of different trade names such as Private Line® (PL) by Motorola, Channel Guard® (CG) by General Electric and generically as tone squelch.

It is a use of sub-audible tones that are transmitted along with the speech portion of the transmission which allows more than one agency (or fleet) to use the same radio frequency without hearing the other agency on that frequency. Receivers for agency XYZ are set to only open their audio squelch when the proper sub-audible frequency tone is part of the transmission.

Today the sharing of frequencies by agencies is less common than it once was, CTCSS is more commonly used by repeater systems to prevent noise or interference from causing the repeater squawk obnoxiously, and by receivers as an extra measure of squelch (for instance, to prevent engine noise from breaking squelch).

The land mobile industry started with some 38 sub-audible frequencies this has increased over the years to the more generally accepted 50. There is no generic standard tone number assignment or code letter to go with a particular tone; however, below is a chart of the commonly accepted 50 tones used at this time.

In addition to the standard tones, some manufacturers have made available additional tone frequencies specific to their own products, but not available to products from other manufacturers.

  • Pseudo Trunking, basically a single freq DMR repeater with 2 time slots/talk paths. Users are normally assigned a time slot, if group A is talking and group B is on the same slot they can't key up while the channel is busy, even if the other slot is open. Pseudo trunk dynamically lets group B use the other slot. This is a single freq trunking system.
  • Multiple repeaters at a site Hytera has XPT, extended pseudo trunking, which makes each slot in any repeater a resource available to any user so they don't have to change channels to find an open slot.

DMR Tier III Hytera vs Tier III CapMax (Motorola)

https://forums.radioreference.com/threads/fastlane-errors.466165/ 

Then, throw in a system like Selex / Leonardo ( search here for: Goosetown Tier III ). It is not a CAPMAX system, but it does not use an Area ID and does not require +1'ing the bits in the Syscode. Unfortunately, there is no OTA information sent that allows DSDPlus to distinguish that it is a Selex system, so DSDPlus presumes its a DMR TIII Standard system and shows AreaID+SiteID and +1's the bits.

I agree, after a few years of seeing TIII systems now, that it would be better to never present the AreaID+SiteID information for a system -- and instead they should be presented as just a model, network ID, and SIte ID. But, I have a feeling DSDPlus would require a significant revamp to do this, and would then require everyone to change how they present aspects of a TIII system in the DSDPlus.* files.

But let's assume that miraculously every piece of software was on the same page using Network Model, Network ID, Site ID. There is still the issue of any software knowing precisely when a SysCode is not presenting "the facts", for every TIII system variant, and thus needing to be +1'd.

I don't think any software developer is every going to get DMR TIII (including all variants -- standards compliant, Capmax, Selex, etc) 100% all the time because we do in fact know that in the DMR TIII standards there is actually an Area ID and a Site ID, and that there is a very important variable (LA -- length of Area) that is not sent over the control channel / not sent in the SysCode information -- there making it impossible to get the Area ID + Site ID combination correct 100% of the time.

 GRE/Whistler scanners can't tell the difference and don't truly trunk track and maybe can't even handle TIII. Uniden scanners can't tell the difference between 100% standards compliant TIII systems and variants like CapMax and Selex. Uniden treats them all the same. SDRTrunk appears to treat them all the same (taking in no account for Area ID+Site ID or +1'ing), but I may be wrong about that -- there may be circumstances where SDRTrunk does +1'ing . I do not use it enough to know. And for anything else handling TIII, I'm pretty sure they aren't attempting to display AreaID+SiteID.

  • When used between 136 – 470 MHz in Part 90 use, this technology is not compliant with 2013 narrowbanding requirements and must be discontinued by January 1, 2013. As of January 1, 2011, this emission may no longer be applied for between 136 – 470 MHz in Part 90 use, unless the applicant certifies that the station equipment meets the narrowband efficiency standard, or the licensee has been granted a waiver of the January 1, 2013 deadline for that station.

VHF Low Band has not been required to narrowband. A 20K0 emission bandwidth continues to be acceptable for nearly all uses.
