Scanner School - Everything you wanted to know about the Scanner Radio Hobby

In today's podcast, I am going to talk about P25 digital technologies on the UHF T-band and how this decision has caused many problems for P25 Trunked Systems.

Scanner School - Everything you wanted to know about the Scanner Radio Hobby

What are TDMA Control Channels on P25 trunk systems, and what does this mean for the scanner radio hobby?   What You Need To Know P25 TDMA control channels are different from P25 phase two voice channels. Every single P25 system out there up until this point has used an FDMA control channel. A new addition to the P25 suite of standards defines a TDMA control channel for P25 trunking operations similar to the FDMA control channel. The TDMA control channel supports the same functionality as the FDMA control channel. However, with the use of that TDMA control channel, a single 12.5 K Hz channel supports two virtual channels and can be configured to utilize one or both virtual channels for inbound outbound signaling. Before current P25 systems can migrate over to TDMA, they need to only have Phase 2 Talk Groups All session notes with links to the items we talked about can be found on our website at https://www.scannerschool.com/session191 -------------------------------------------------------------- Free SDR Course!

What You Need To Know There is a shortage in the new market for P25 type scanner radios, especially SDS100 and 200, but prices are the same as for new ones in the used markets. The used market will dictate a solid price for that kind of radio because of less supply and high demand. eBay is the largest second-hand market for used scanner radios. The Facebook marketplace is another option for scanner radio purchases, but it is advised not to use the Facebook payment program as there is no protection. One can also find scanner radio-like stuff at Craigslist, and it's better to find some cash-only deals from Craigslist. Don't be fooled by a scanner listing if someone simply puts the word "vintage" in the title. If a radio has been well maintained or in collective items or still in the box with manual and never been used, those radios collect a premium.

Free SDR Course! Our new free course will introduce you to Software Defined Radios. "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 --------------------------------------------------------------- In today's episode, I will discuss shortages of scanner radios, which models of scanners may be out of stock, and why this could be.     What You Need To Know Brand new P25 style scanners have become hard to find in the last year and a half. This is especially true for the SDS100 and 200, as well as the TRX-1, and TRX-2. They seem to be out of stock from everywhere in the market. A partial and obvious reason for the shortage of P25 scanners is COVID. In this Pandemic situation majority of people were staying home or working remotely. Many of them come back into scanner radio hobby after being not involved for some time. During the pandemic, numerous people were introduced to scanner radio hobby or something they want to do, and now they are just picking on that hobby. It's not only the scanner radio market with shortage issue; it's also beyond the radio and communication market. In the shipping industry, we have a shortage of dock workers due to COVID, and they are not working in total capacity, which causes ships not to load and unload fast, and ships are queued for longer than their routine trip. Containers from the ship are unloaded on trains or trucks, but as the truck drivers are sick due to COVID, the movement, loading, and unloading of containers are significantly less, causing a shortage of containers to difficulty in moving inventory. Silicone issue or the microchip problem has been a global issue, and everyone is looking for these microchips. Demand for microchips is exceptionally high due to a surge in people wanting electronics equipment as they are stuck at home. It takes almost a year to get the chip designed and ready to be manufactured from start to finish, and these are built on wafers.  Everything is based on microchips and all these come from the part of the world where there is a shortage of workers due to another wave of coronavirus. If you are in the market for new scanner radio, put your name on any email list that you find by major scanner sellers like scanner master. Because of the shortage of new scanners, the used market for some of these hard to find scanners is very strong. eBay, Facebook, and the Radio Reference Classifieds are a great place to find scanners radios on the secondary market.

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!

Do you want to understand how trunking systems work in your Object Oriented Scanner? In this episode, Phil continues his miniseries about trunking systems. He walks through optimizing your Whistler, GRE, and Radio Shack scanners for trunking using their object-oriented scanning.   What You Need To Know Think of a site as a repeater that transmits radio and control channel traffic for its coverage area. Whistler allows you to have more control over your trunk scanning thresholds than Uniden. To optimize your sites, you need to know what talk groups are most likely to be broadcast on what sites. When you’re programming your Motorola or P25 trunk sites on a Whistler, you only have to input a list of every single control channel on every site you want to monitor, rather than having to break it out by site like on Uniden. Whistler has multi-site settings including Off, Roam, and Stationary. Off means, the scanner will find the first usable control channel and use it to track the systems without bothering to scan the others. Roam is used if you’re driving or otherwise moving around and will lock onto the best site it can find based on your Threshold High and Threshold Low settings. Stationary allows you to scan through all decent quality control channels while you remain in one place. Butel software makes duplicating these scan lists much easier than using the keypad.

Do you want to understand how trunking systems work? In this episode, Phil explains how trunking system networks, sites, channels, and layers all work together and gives some examples both from his local area and more hypothetical use cases.   What You Need To Know This episode ties into last week’s episode about programming groups. A Motorola type 2 trunking system is capable of having 28 channels per site. A Smart Zone system is a collection of Smart Net systems Smart Zone networks have dynamic site assignments, meaning that if a radio or talk group is not affiliated with a site, then it does not need to be broadcast on that site. Although he uses a Motorola system as an example, these explanations also apply to DMR and P25 radio systems. In Phil’s county, they have simulcast sites on different frequency bands. These sites on this system may or may not broadcast the same talk groups. Trunking systems have multiple sites in order to efficiently use the resources available, freeing up channels for local users.

You can grab the show notes for today's podcast at www.scannerschool.com/session15 You can also take a look at our glossary for all of the acronyms we used in this session at www.scannerschool.com/glossary      We also have a live Facebook Q&A Session every Saturday at 11am.  Join us at www.scannerschool.com/facebook   73 Phil / w2lie

Scanner School - Everything you wanted to know about the Scanner Radio Hobby

Welcome to P25 aka Project 25 aka APCO-25. We talk about the 8 modules that make up a P25 system and how they operate. P25 Conventional is covered as well as NAC. P25 Trunking, Phase 1, Phase 2, and X2-TDMA will follow in next week's session of the Scanner School Podcast. If you haven't subscribed to our podcast, please do so now so you don't miss next week's session.

Scanner School - Everything you wanted to know about the Scanner Radio Hobby

Be a fly on the wall on one of my consulting sessions with Jon Goldenberg.   Jon was one of the winners of the Free Consulting Contest that we had in February of 2018. Jon and I discuss his current scanner needs and discuss some ways on how he can setup his scanners. We talk about the local P25 and EDACS Trunk systems, close call, P25 threshold settings, and if he should consider using multiple scanners for his monitoring needs. There is also an idea I have been tossing around at the end of this session, so please be sure to list to the full podcast to know what I have planned at the end of this week.  

Scanner School - Everything you wanted to know about the Scanner Radio Hobby

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. You can download session notes for this podcast, as well as additional resources at http://www.scannerschool.com/session12 We also have a new e-guide available for anyone looking for their first scanner.  Download a copy of the "5 Things You Need to Know Before Buying Your First Scanner" at http://www.scannerschool.com/newscanner

What use is an F-call?

What use is an F-call? Digital Voice in Amateur Radio is broken. It's a big call for a mere F-call to make, so let me back that up with some facts. There are three basic digital voice products you can buy as an amateur today, D-Star made by ICOM, System Fusion made by Yaesu and MOTOTRBO or TRBO by Motorola. There is also Project 25, or P25. Each of these systems are based around technologies and patents owned by a company called Digital Voice Systems Inc. or DVSI. In essence, each of these systems use the same maths to encode and decode an audio signal. This process of encoding and decoding is embodied in a thing called a Coder / Decoder or CODEC. While each of these use the same maths, owned by the same company, they don't actually inter-operate. What that means that if you want to use a D-Star repeater, you need a D-Star radio, and if you want to use a System Fusion repeater, you need a System Fusion radio, even though both radios use the same maths to make your voice into a digital signal. It gets worse. If Elecraft wants to build a radio that talks to three systems for example, they would need to license the same technology three times, at exhorbitant cost. Most of these are actually achieved by buying a chip from DVSI, not to make it faster, but to protect their maths against people reverse engineering it. It also means that if you want to experiment with Software Defined Radio, you cannot use it to decode D-Star, System Fusion or TRBO, because the costs to license the technoogy is not viable for anyone other than commercial users. In January 2014 I was lucky enough to attend the Linux Conference Australia which at the time was being held in Perth, 15 km from my QTH. Being a comper nerd and becoming a radio nerd meant that this was an opportunity too good to miss. You may have heard some of the 50 interviews I did at that conference. One of the reasons I did those interviews is to begin the process of making my fellow amateurs aware of other ways of doing business. Open Source and Software Freedom are important concepts that relate directly to Amateur Radio. People like David Rowe VK5DGR and Bruce Perens K6BP are at the forefront of developing and advocating alternatives, like Codec2, a piece of software written by David to address this specific problem. Amateur Radio is an experimental hobby. What we do is play with stuff, break it, put it together in new and innovative ways, research and develop. None of those things are possible with Closed Source encombered products like the stuff that ICOM, Yaesu and Motorola are flogging. Yes it's great, it's digital, it improves many things like battery life, bandwidth use and channel separation, but it's also broken. There are 4 and a half D-Star users in VK6, 2 System Fusion users and I'm not aware of any TRBO users. Those numbers are in jest, but this is not widely used technology, despite the fact that digital voice adds many benefits to Amateur Radio. On the other side of the fence, every Amateur Radio has AM, FM, SSB and CW, precisely because there are no such restrictions. Next time you buy a shiny new radio, or advocate a new technology, or invite a trojan horse like a free repeater, it would pay to notice the other issues that the sales people gloss over.
