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."

Squelch / Carrier Squelch / Codes

Squelch

  • Squelch is used in two-way radios and VHF/UHF radio scanners to eliminate the sound of noise when the radio is not receiving a desired transmission.

Carrier Squelch

PL (CTCSS)

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).

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. 

Because period is the inverse of frequency, lower tone frequencies can take longer to decode (depends on the decoder design). Receivers in a system using 67.0 Hz can take noticeably longer to decode than ones using 203.5 Hz, and they can take longer than one decoding 250.3 Hz. In some repeater systems, the time lag can be significant. The lower tone may cause one or two syllables to be clipped before the receiver audio is unmuted (is heard). This is because receivers are decoding in a chain. The repeater receiver must first sense the carrier signal on the input, then decode the CTCSS tone. When that occurs, the system transmitter turns on, encoding the CTCSS tone on its carrier signal (the output frequency). All radios in the system start decoding after they sense a carrier signal then recognize the tone on the carrier as valid. Any distortion on the encoded tone will also affect the decoding time.

Engineered systems often use tones in the 127.3 Hz to 162.2 Hz range to balance fast decoding with keeping the tones out of the audible part of the receive audio (Courtesy WikiPedia)
  • Many NATO military radios have a switchable 150.0 Hz tone. The list includes the following radios: AN/PRC-68, AN/PRC-117F, AN/PRC-117G, AN/PRC-77, AN/PRC-113, AN/PRC-137, AN/PRC-139, AN/PRC-152, AN/PRC-119, AN/VRC-12, AN/PSC-5, and Thales AN/PRC-148 MBITR. (from Wikipedia)

DPL/DCS/CDCSS

  • CSQ....
  • Standard codes
  • Digital-Coded Squelch (DCS) system was developed by Motorola under the trademarked name Digital Private Line (DPL). General Electric responded with the same system under the name of Digital Channel Guard (DCG). The generic name is CDCSS (Continuous Digital-Coded Squelch System).

DCS (Digital-Coded Squelch), generically known as CDCSS (Continuous Digital-Coded Squelch System), was designed as the digital replacement for CTCSS. In the same way that a single CTCSS tone would be used on an entire group of radios, the same DCS code is used in a group of radios. DCS is also referred to as Digital Private Line (or DPL), another trademark of Motorola, and likewise, General Electric's implementation of DCS is referred to as Digital Channel Guard (or DCG). Despite the fact that it is not a tone, DCS is also called DTCS (Digital Tone Code Squelch) by Icom, and other names by other manufacturers. See DCS on WikiPedia


  • The use of digital squelch on a channel that has existing tone squelch users precludes the use of the 131.8 and 136.5 Hz tones as the digital bit rate is 134.4 bits per second and the decoders set to those two tones will sense an intermittent signal (referred to in the two-way radio field as "falsing" the decoder) (From WikiPedia)

* In this same sense, RadioShack/GRE/Whistler scanners may show 136.5 PL on a poorly received transmission using DCS.

NAC

  • Used in P25, conventional and trunking
  • Often pronounced as "Nack" or "Nax" (plural), but can be said as "N" "A" "C". Can be abbreviated to "N" or $, ie $%070

  • 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.

P25 Trunked on VHF

MOSWIN

Missouri Statewide Wireless Interoperable Network (MOSWIN)

  • For Example,, in Missouri P25 PDF
  • Uses Federal Government frequencies for this project, Devices must operate throughout the 138-174 MHz VHF High band (see the link above for more system requirements)
  • Device must be capable of Advanced Project 25 Control Channel functionality that enables explicit trunking. Due to the lack of standardized channel pairings in the public safety VHF High Band spectrum allocation, higher tier P 25 control channel functionality is required in subscriber devices on the MOSWIN network for it to be able to explicitly trunk and specifically assign unique, site based VHF channel pairings to a subscriber radio based on channels available, thereby enabling the subscriber to access the network.
  • This specific method of granting a channel is a more extensive process for the network’s Control Channel than in implicit trunking, where the channel pairings are standardized and a reduced amount of messaging on the Control Channel dedicated to channel granting is required for each channel assignment. In addition to the above criteria, subscriber units proposed for use on MOSWIN need to be tested on the MOSWIN network to ensure consistent operation. Experience in other states, using both VHF High Band and 700/800 MHz Wide Area trunked systems, indicates that field testing of subscriber units prior to system certification is necessary to ensure that the full functionality of the subscriber is achievable and expectations of the users are verified. Those field tests include roaming throughout a system to ensure the subscriber transfers across all the zones of a system and we look forward to working with the vendor community on developing those tests.
  • The Missouri Department of Public Safety anticipates developing a certification process in which subscriber units from multiple manufacturers can be approved to operate on MOSWIN.

  • I would keep an eye on the slots. It's very possible that the talkgroups can be used on either slot.
  • For example Ch. 4 has traffic, which is on SLOT 1, then Ch.2 wants to talk at the same time, ...It will go on SLOT 2, while SLOT 1 is still carrying the traffic on Ch 4. Ch 4 could stop for a second and Ch 2 could switch to SLOT 1. While Ch. 2 is on SL1, Ch. 4 starts back up again and will used SL2 (if they both are still carrying traffic

  • Radio/TV
  • The smaller the channel spacing, the more users that we can fit in a block of frequencies
  • The wider the channel spacing, the better the reception and audio fidelity
  • 25 KHz - Wideband
  • 12.5 KHz - Narrowband* (1/2 of wide)
  • 6.25 KHz - Ultra-Narrow (1/2 of narrowband)

  • 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.

Encryption

  • Encrypted frequencies or talkgroups CAN NOT be monitored with-out permission of the agency. That agency may issue a Encryption Key for use in a two-way radio or Unication Pager to be able to monitor.
  • Types of Encryption:
  • Motorola radios require a MACE module and software upgrades

Mobile Extender/Vehicular Repeater/DVRS

Pyramid Communications

  • The "original" vehicular repeater system. Made in the United States.
  • All VRs work on a simplex channel. Can work IN-BAND with filtering options.
  • VHF In-Band requires both the BPF-1604 Band Pass Filter and VHF Notch Filter. SVR Simplex MUST be 2 MHz or 5 MHz, or greater from all mobile frequencies (both TX and RX). The Notch filter is made in the 2MHz and 5MHz, with obviously the 2 MHz costing more. NOTE: This doesn't just mean the main channel you use, but ANY channel that may may need to use on the VR.
  • (integrate above) BRF-1601 Notch Filter for as close as 5 MHz separation between mobile TX/RX and SVR-200. Use the narrower BRF-1602 Notch Filter for frequencies as close as 2 MHz separation
  • VHF In-Band repeating is the most popular method of deployment, per Pyramid. Be aware, the 173 MHz MO3 frequencies are already crowded, at least with licenses in many areas. Much of this being used as constant data transmissions for water or waste-water monitoring systems.
  • Pyramid (spent 5 years) worked to secure new MO3 channels on 173.2375, 173.2625, 173.2875, 173.3125, 173.3375, 173.3625. These are SHARED with telemetry users (as stated above). Recommended to work with EWA for licensing of these frequencies, as they helped. APCO or any Public Safety coordinator "Should" be able to help though.
  • UHF In-band DOES NOT require the use of a Band Pass Filter (, only the Notch Filter. The Notch Filter must be 5 or 10 MHz away from ALL mobile frequencies (both TX and RX).
  • Multi-Band Radios and In-Band - New TPLX-V-U-M 100W VHF, UHF, 7/800 MHz Triplexer, works with Kenwood and Viking..... Harris Unity or APX-8500 mobiles only have one antenna connection for all bands.
  • Multi-Vehicle Priority: One unit on a scene will provide priority traffic, without interference from other VRs. MO3 2W Maximum Power
  • Webinar on youtube "Pyramid Digital Vehicular Repeater Webinar" on Pyramid Communications channel
  • Bandpass Filter: The BPF-1604 is a high selectivity pre-selector filter that prevents the mobile’s transmitter from overloading the SVR-200VB receiver’s front end. The filter is tuned to the SVR-200’s simplex frequency and rejects everything except a narrow band of frequencies centered around the SVR-200 frequency.
  • Notch Filter: Transmitters are designed to broadcast on a specific frequency, but no matter how good the design of that transmitter, it produces RF energy across a broad band of frequencies. The FCC sets limits on how much “off-frequency” energy a transmitter can produce, but even within the limits, it may be enough to cause interference in a receiver located close by, such as the SVR-200. No amount of bandpass filtering on the SVR-200 will reduce this interference since it is right on the SVR-200 receive frequency. The BRF-1601 or BRF-1602 notch filter is tuned to the SVR-200’s receive frequency but installed on the mobile’s antenna cable. The notch filter further attenuates the noise produced by the mobile that occurs on the SVR-200 receive frequency. This is also why frequency spacing is so critical. None of the mobile’s frequencies, transmit or receive, can be within 5 MHz using the BRF-1601 or 2 MHz using the BRF-1602. If a mobile transmit frequency is too close, the filter will consume too much of the transmitter power, damaging the filter and possibly the transmitter. If a receive frequency is too close, the mobile’s receiver sensitivity will be degraded.

DVRS (Digital Vehicular Repeater System)

  • In-Building etc.
  • See Futurecom See YouTube. "DVRS Explainer Video" Owned by Motorola Solutions as of Oct 2022 LINK For over 30 years, Motorola Solutions and Futurecom have collaborated on RF repeaters and extenders that are tightly integrated with Motorola Solutions’ radio networks and devices. These solutions help to ensure that first responders, even in remote locations, maintain critical communications and advanced features, such as encryption and data services, to do their jobs more safely and securely. FUTURECOM HAS A GREAT SELECTION OF VIDEOS ON YT: (LIST HERE) that explain how they work. Neat!
  • Example - Illinois State Police are using VHF P25 DVRS to extend their 700/800 MHz STARCOM21 mobile radios, etc. This CONVENTIONAL P25 system still passes through the P25 NAC, Site ID, RFSS, RID/UIDs, Talkgroup numbers. On a Uniden scanner it looks just like you are on the P25 Trunked System voice channel.

BDA/DAS In building Antennas

  • In-building signal booster solutions typically include three key components: (from [1])
    • A donor antenna that is mounted on the roof to seize the wireless signal from the outside.
    • A Distributed Antenna System (DAS), which is a group of antennas placed throughout the structure to boost signal coverage.
    • Bi-Directional Amplifiers (BDAs) that extend two-way radio coverage into difficult-to-reach areas, such as stairwells, underground hallways, tunnels, parking garages, and other challenging zones. (Depending on size, materials, and structural design, some buildings may not require a BDA, or a standard two-way radio Repeater may be sufficient.)
  • Many buildings benefit from having BDAs, including hospitals, office buildings, schools, manufacturing plants, sports arenas, and more.
  • Depending on the equipment chosen and how it is installed and programmed, BDAs can be deployed to improve team communications for facility staff who use two-way radio systems (usually VHF or UHF bands) and/or to meet Public Safety radio coverage requirements, as required by law (usually on the 450/700/800 MHz bands).
  • Public Safety radios help keep first responders in contact with each other during an emergency. It increases their safety, but it helps public safety professionals serve building occupants and visitors better, as well.
  • Cellular BDA is also available to help improve cell coverage in buildings. These are specifically for cellular devices and will not increase two-way radio coverage. Therefore, it’s recommended to install two separate systems for your building: one for two-way radios and one for cell phones.


ANTENNAS

  • Note: Some antennas are made to RECEIVE ONLY. So may be able to transmit a certain amount of wattage.
