Podcasts about nxdn

Digital modes, like P25, NXDN, DMR and others will use FDMA, TDMA, or both allow multiple transmissions to share a single frequency at the same time. FDMA or Frequency Division Multiple Access divides a current carrier frequency into multiple parts, allowing for multiple users to operate on the same time on the same frequency. TDMA or Time Division Multiple Access divides a current transmission over time, allowing for 2 or more users to share a the same frequency at the same time, depending on the digital protocol that is used. The ability for these digital transmissions to place multiple users on the same frequency allows for better management of the limited radio spectrum resource. Not only does this allow for more frequencies to be distributed, but allows for end licenses to do more with a single radio license. Learn the differences between FDMA and TDMA in this week's podcast. ====================================

Once upon a time, we only had analog trunked radio systems.   These systems all had analog voice talk groups. These systems included Motorola Type I, Motorola Type IIi, Motorola Type II, EDACS, and LTR systems. Today, we are living in a digital trunked environment, where there are no analog voice channels.  All voice is done using a form of digital modulation.   These systems include P25, DMR, and NXDN. But, we had an in between.  This is where we had digital talk groups on an analog trunked system.  On a Motorola Type II system, we could find P25 talk groups.  On EDACS systems, we'd find ProVoice talk groups. This podcast will discuss analog and digital systems, and explain why our older P25 scanners like a Uniden BC785D will not work on today's P25 Trunked systems. ====================================

Finally - not one, but TWO new scanners from Uniden. Should we be excited about these two new radios, or should we pass on them? That all depends on your location and your needs. See, these scanners break the mold and give us something we've never seen before A scanner radio, with no trunking, no P25, but supports DMR and NXDN. Who is this radio for? The answers are in this week's podcast.   ====================================

Amateur Radio Operators are very resourceful when it comes to surplus equipment. Did you know that there are P25, NXDN, and DMR amateur radio repeaters in most corners of the world?   These repeaters are easily linked, allowing world wide communications during emergencies, events, and day to day activities. There are also HAM specific digital voice networks, like DSTAR, YSF, and M17 that you can easily monitor. There is also a Scanner Radio Net on DMR you can check out.  Details are in the podcast. ====================================

Today we will be talking about War driving with your scanner radio to find frequencies that are in use during your day-to-day travels. War driving is a term that comes from the Wi-Fi cracking or hacking hobby which basically means searching for open Wi-Fi wireless networks usually from a moving vehicle using a laptop or a smartphone. “War Driving” can be one of the more interesting ways to find new frequencies. What You Need To Know War driving is kind of a hit and miss type of deal, but it's very rewarding when things happen. You can find local repeaters that we did not know existed You may hear local businesses using frequencies or security agencies. Is it possible to security companies to use their own frequency? Yes, it is possible that they might be using the school's frequency. War Driving a fun way of finding out information or finding out what else is out there. Anytime you go out is an opportunity for you to put the scanner into a search mode and see if you can hear anything local. I recommend having a scanner that covers all the modes you're interested in like P25, NXDN, DMR, analog and digital scanners that should be able to record if you are mobile.   ====================================

Have we reached the end of the scanner radio hobby? I know many feel this way due to encryption and a lack of new scanner radio models being released. However, this hobby has been around for decades and there is no reason why we can't enjoy this hobby in some form or another for decades to come. Some Feel / Think: Live feeds are killing the hobby Many agencies will be going encrypted to keep people from listening Scanners are becoming too much money due to simulcast Other agencies are going off radio and onto IP solutions Manufacturers won't invest in scanners due to widespread encryption UK laws and going fully encrypted is the future in the US Current chip shortages hurt hobby Lack of interest from whistler How is might be wrong There will always be skeptics Some aren't happy unless they are making noise and being negative There will always be something to listen to  Secrets are in the searches – what else is out there to hear? What can we listen to now that should always be there? Aviation Rails Ham CB GMRS Businesses DMR / NXDN Systems Utilities Security Firms My Thoughts Resurrection of the hobby due to new hardware and interest Software Defined Radios are introducing more people to the hobby They get into it because it's something to do with a computer Learn about NOAA weather satellite reception Opens them to more projects and learning opportunities  Manufacturers will continue to make low end analog only scanners as they have for years Top of the line scanners today will become mainstream designs and hardware, dropping the overall costs as time goes on. Pandemic had people dusting off old hobbies and picking up new ones Conclusion: Scanning is following the same course as other hobbies As technology changes, we see changes in scanning.   No More crystals Evolution of Motorola Trunking Inclusion of EDACS and LTR Eventual support of P25 phase 1 Support for phase 2 NXDN and DMR Simulcast Will Tetra come to the next evolution of scanners? Scanning will continue to be here for years and decades to come, as long as there is something out there to listen to. ====================================

Looking at things from multiple angles may help you think about whether it is time for you to consider upgrading a scanner.   Do you want a new scanner because it's time to buy something new, or is it needed to keep up with changes to your local systems? What You Need To Know There are things outside of our control dictating whether or not we need to upgrade our scanners. For example, when rebanding happened here in the US, many of us needed new scanners that would support rebanding. Paying for a DMR or NXDN upgrade might be a nice upgrade if you already have supporting hardware. Size matters. Upgrading into a “pocket scanner” might interest you if you are always carrying a radio around. Scanning is a hobby. Learning, growing, and investing in equipment is what a hobby is all about. The secondary market can be a great place to purchase radios, that were too expensive when new, at a more affordable price today.   ====================================

Weather Alert Standby is a feature in many newer analog scanners SKYWARN traffic is typically on amateur radio analog repeaters. Fire Tone Out is another feature found in many analog scanners. News and media frequencies are very busy and you can hear interesting transmission on those frequency ranges. Shopping malls and departmental store use FRS radios that are analog. Put your old analog scanner in search mode, put it into close call mode, and see what is close to you or what is around you. You can tap into discriminated baseband audio or raw audio or unprocessed or unfiltered audio of the board of your scanner.   All session notes with links to the items we talked about can be found on our website at https://www.scannerschool.com/session181 --------------------------------------------------------------- Would you like 1 on 1 help?

"The Ultimate Beginner's Guide to Software Defined Radio: Everything you need to know to get started with SDR in an afternoon" is now open for enrollment.  Register now at https://courses.scannerschool.com --------------------------------------------------------------- Today we break down the similarities and differences when it comes to Scanners and Receivers What You Need To Know Scanners and Receivers are more like cousins than brothers and sisters in the radio world.  Both receive and scan frequencies They don’t transmit. Receivers have a larger receive foot-print than a typical scanner.  Typically 100 KHz is the bottom of a receiver, but you can go up to a couple of gigahertz. A typical scanners start as low as 25 MHz and go up to 1300 MHz Scanners will typically not support monitoring AM Broadcast Bands, but Receivers will. Scanners do not support SWL monitoring, but Receivers will. Scanners have more modes that are not found in receivers; NXDN, DMR, P25, are common modes of reception present in a scanner. Receivers have modes that are not in present in a scanner, such as upper and lower sidebands, AM and CW Some high end receivers will do D-STAR, P-25, dPMR, and NXDN. Receivers can be very affordable starting less than $200 and going over $10,000 for a high end model. Scanners can start at $100 and cost over $600 for a high end model. With close call and signal stalking, scanners can help you find a more relative frequency faster than a receiver.  All session notes with links to the items we talked about can be found on our website at www.scannerschool.com/session174 --------------------------------------------------------------- Would you like 1 on 1 help?

In this episode, Phil goes through a rapid-fire rundown of Trunk Systems. This is part 2 of this 2021 crash course. What You Will Take Away from This Week's Podcast: Trunking means that multiple users share pooled frequencies, allocated on an as-needed basis. Each talk group is assigned a frequency to use, which is more efficient than conventional systems. These systems can be linked together into networks. The control channel can be considered air traffic control or the traffic cop at an intersection; when a user keys in they request a voice channel, and when it’s no longer in use, everyone moves back to the control channel. Types of trunking include EDACS, Motorola Type II, P25, DMR, LTR, NXDN, and more. Rebanding came about because NexTel purchased ESMR frequencies, which resulted in cell phone band frequencies moving up 15MHz and public safety bands moving down 15MHz. Simulcast is when you have multiple transmitter locations keying up at the same time and broadcasting the same information over the same frequencies.  All session notes with links to the items we talked about an be found on our website at www.scannerschool.com/session161 --------------------------------------------------------------- Would you like 1 on 1 help?

2020 Holiday Buyer's Guide Are you wondering what should be on your holiday shopping list this year? In this episode, Phil shares his 2020 holiday buyer’s guide, helping you compare radios, scanner software, and accessories. What You Need To Know This year’s buyer guide is the same as the 2019 buyer guide because no new equipment has been released. East Coast Pagers will have great Black Friday deals. Uniden SR30C: A radio at the lowest price point with minimal features. Phil recommends instead upgrading to the Uniden BC125AT. Recommended analog trunking scanner: Uniden BCT15X For digital radios, Phil compares and contrasts the Uniden BCD325P2, BCD996P2, and the UBCD325P2, which all support P25 Phase 2. If you don’t need Phase 2 P25, Phil recommends the Whistler WS1040 and the WS1065. The next step up is the Whistler TRX1 and TRX2, which come with NXDN and DMR right out of the box. The Uniden BCD436HP and BCD536HP radios are Phil’s current go-tos. Internationally, Phil recommends the UBCD3600XLT, which is the overseas version of the BCD436HP scanners. Phil’s current “holy grail” scanners are the Uniden SDS100 and SDS200, despite some of the issues they have had. The Unication G2 through G5 are pagers work well in P25 Phase 2 Simulcast environments.   We also have a top 10 accessories in the second half of this podcast All session notes with links to the items we talked about an be found on our website at www.scannerschool.com/session152 If you need help with your scanner and are looking for some one on one tutoring, I'd love to help you out.  Visit www.scannerschool.com/consulting to book your one hour appointment today!

The Scanning hobby is ever-changing. Who would have though that at the start of the 2010's we would see touch screen scanners, be able to receive DMR and NXDN, and also use SDR's to pickup almost any signal out there? What will the next one hold? In this podcast, we discuss what has happened over the last decade in scanning and what might be coming in the future. What do you predict we will see in the hobby in the next 10 years? All session notes with links to the items we talked about can be found on our website at www.scannerschool.com/session106

NXDN stands for Next Generation Digital Narrowband   For an introduction to NXDN, please see last week's podcast at www.scannerschool.com/session43 NXDN Trunking comes in two classes: NXDN-C and NXDN-D NXDN-C is like most trunking systems.  There is a control channel and a set of voice channels. NXDN-D is similar to LTR Trunking, where you have no dedicated control channel.  Your users are listening to a home channel and any channel can be used as a voice channel Please be sure to view the session notes for all the sources on both last week's and this week's podcast All session notes with links to the items we talked about can be found on our website at www.scannerschool.com/session44   Please support the Scanner School podcast.  Visit www.scannerschool.com/support to see how you can help us.  Some of the ways you can support us won't cost you any additional money!  

NXDN stands for Next Generation Digital Narrowband NXDN was created in 2003 with a joint venture of Kenwood and Icom.   The protocol was announced at IWCE in 2005 and the first units arrived in 2006.  It wasn't until 2017 that NXDN was published by the ITU-R as an international digital land mobile system. NXDN was created to satisfy the 2005 FCC Narrowbanding mandate.  Originally created for business users, NXDN is used by public safety and even the military. Overseeing NXDN development and standards is the NXDN Forum.  A 30 member community including JVC Kenwood, Icom, Anritsu, The Boeing Company, and Zetron. NXDN Comes in 3 flavors NXDN Standard (As defined by the CAI) Kenwood's NEXEDGE Icom's IDAS  NXDN operates using FDMA over 12.5kHz or 6.25kHz wide bandwidth.     All session notes with links to the items we talked about can be found on our website at www.scannerschool.com/session43   Please support the Scanner School podcast.  Visit www.scannerschool.com/support to see how you can help us.  Some of the ways you can support us won't cost you any additional money!  

In this session of Scanner School, we review scanners that support "Analog" trunk systems, or systems that are not completely digital like P25, DMR, or NXDN.   These scanners are sometimes called Trunk Tracker III scanners and the scanners we review in this session all support rebanding.

From the archives of Amateur Radio//Video News... Digital Voice for Amateur Radio was the most complex of the three documentaries that HamRadioNow's Gary Pearce KN4AQ produced for DVD, before starting the online show. In 2007, Gary traveled to Alabama and Dallas in one trip, Chicago and St. Louis in another, and Washington DC in a third to gather interviews and footage of what was then just emerging as Digital Voice systems for Amateur Radio. The program was edited and released on DVD in 2008. The DV modes included an HF mode called WinDRM (which evolved to today's FreeDV), and VHF/UHF modes D-STAR and P-25.  Of course, these modes have evolved since this program was produced, and newer modes like DMR, Yaesu System Fusion, and NXDN have been developed. Consider this program a snapshot in the early history of Amateur Radio Digital Voice. It's certainly not a current tutorial on operating those modes today. Radio Rating: C- at best. This was a video documentary, and while there is a lot of talking, most of the pictures you're missing are equipment in operation, locations, and a few graphics. You'll miss a lot, but since there's so much information, you'll learn a lot, too. [The Radio Rating is our estimate of how much you'll get from the program audio without the video. It's not a rating of the overall program. Those are always A+]

I spent the last week or so tinkering with the software fr this radio, which was a huge learning curve. This video will be Part 1, and after I've spent more time getting used to the radio, I'll record another video for it.
