  • Raspberry Pi 5 is here!

    Hi Members, You may be wondering why I have added a item such as this new Raspberry Pi 5, well these are used for making Amateur Radio Hot Spots which then can run the Pi-Star software, for use when connecting to the digital world such as DStar, DMR etc etc etc.. They are small yet powerful mini computers and can be used for all sorts of electronic and computer applications. Here are details from Core Electronics.. We have an absolutely huge announcement, the most popular single-board computer is getting an upgrade! That's right, Raspberry Pi 5 is here and we managed to get our hands on one and have put it through it's paces - check out our RPi 5 review video on YouTube (highly recommended!). We also have a video for those interested in RPi 4 vs 5 benchmarks. Stock is expected in the coming weeks; sign up on either the 8GB or 4GBproduct page to be notified the moment happens. The CPU has been treated to level-up with the 64-bit quad-core Arm Cortex A76 processor clocking in at 2.4GHz, this gives the Pi 5 a 200-300% increase in CPU performance compared to the previous generation. Peep pixels for days with the 800MHz VideoCore VII GPU, providing dual 4Kp60 display output over HDMI with HDR support. I hope you like taking pictures because the Raspberry Pi Image Signal Processor has been overhauled featuring speeds up to 1 Gigapixel per second, providing exciting new applications for consumers and industry alike. Peripheral performance and functionality has seen a mighty boost thanks to Raspberry Pi's first in-house built silicone on a full-size Pi. The RP1 "southbridge" handles the majority of I/O for the Raspberry Pi 5 with some pretty impressive qualifications. Transfer speeds will see an improvement with combined USB bandwidth more than doubling. Peak performance over SD card has doubled with the support for SDR104 high-speed mode. Gone are the old CSI and DSI MIPI interfaces of the Pi 4, replaced with 4-lane 1.5Gbps MIPI transceivers that are interchangeable, allowing any combination of two cameras or displays. The icing on the cake however, a single-lane PCI Express 2.0 interface, opening the possibilities with support for high-bandwidth peripherals. Not to mention the onboard Power Management IC is hiding a few tricks up its sleeve. USB PD is now enabled which is just in time for the new 27W USB-C PD Power Supply which provides the Pi 5 with 5.1V/5A. A real-time clock (RTC) is now onboard powered by an external battery, and how can we forget the much welcomed power buttonmaking things easier. The Raspberry Pi Casehas received an makeover as well, with improved air flow and an integrated variable-speed fan to help support the higher peak power consumption of the Raspberry Pi 5. But power users are going to be excited for the Raspberry Pi Active Cooler a large heat sink & variable-speed blower that mounts to dedicated holes on the PCB and is driven by the fan connector onboard.

  • How digital capacitor ICs ease antenna tuning

    BYBILL SCHWEBER The need for what’s called antenna tuning—either by adjusting the antenna itself or via a matching circuit between power-amplifier output and the antenna—is almost as old as wireless itself. Even in those early days, electromagnetic theory and hands-on practical experimentation showed that effective power transfer and optimal antenna performance, measured by several parameters, require that the source impedance and the load impedance be complex conjugates. The problem has not gone away, but instead has morphed into a new and more-challenging form. Traditionally, antenna-matching circuits were built into smaller, lower-power radio designs; in other cases, they were and still are offered as commercial units in external enclosures. This was due to the high-power ratings spanning tens, hundreds, or even thousands of watts, along with the physically larger values needed at the lower frequencies of tens or several hundred megahertz. Some of these external tuners were designed for a single band, while others for multiband use cases, such as amateur or ham radio, which had front-panel switchers to enable adjustment settings for the different bands in use (Figure 1). Figure 1 This variable L-network random wire antenna tuner is designed for manually matching the low output impedance of transmitter (up to 200 watts) to the high impedance of a random wire (or vice versa) from 2 to 30 MHz. Source: MFJ Enterprises Many of them are one-off, hand-crafted works combining artful form and required function (Figure 2). Figure 2 Many amateur-radio enthusiasts prefer to design and fabricate their own antenna-matching units for their bands of interest and power levels, such as this one covering 3 to 30 MHz and handling up to 150 watts. Note the toroidal transformer with multiple windings. Source: Newer antenna tuners incorporate autonomous self-controlled auto-tuning using an internal processor or allow an external PC to do so via an USB port. New applications, new approaches But as the saying goes, times have changed. Now the tuning battle is over 5G and even 4G phones supporting multiple bands and embedded antennas such as the widely used planar inverted-F antenna (PIFA). Smartphones are relatively low-power devices operating above a gigahertz with multiple bands, which must be supported with seamless band transitions and handoffs. The associated LC values are small, which simplifies the challenge in some ways, but also makes it harder in other ways. Complicating the situation, the matching values are not static but are dynamic in routine use as user’s hand changes location and angle, and phone’s position moves with respect to the head and body. Certainly, expecting the user to tune and optimize the antenna-matching circuit in use is simply not an option. Fortunately, there are now solutions to this dilemma via antenna-tuner ICs. These ICs address the issue by allowing digital setting of up to 16 capacitance values, thus changing the electrical characteristics just enough to optimize the matching or get close enough. Among the vendors are Peregrine Semiconductor (PE64909), Qorvo (QM13025), Skyworks Solutions (SKY59272-707LF), and Infineon (BGSC2341ML10). Unlike lower-frequency matching circuits with capacitance in the tens of picofarads, and even extending to the microfarads range, these ICs allow tweaking of very small capacitance shifts. For example, the Peregrine Semiconductor’s PE64909 device is a digitally tunable capacitor for 100-3,000 MHz (Figure 3). Figure 3 The PE64909 antenna tuner IC has a simple function and schematic (above), but its equivalent-circuit model is more complicated (below). Source: Peregrine Semiconductor In operation, a system processor can use a four-bit code to select one of 16 capacitance values via its 3-wire, SPI-compatible serial interface, serving from 0.6 pF to 2.35 pF (a 3.9:1 tuning ratio) in discrete steps of 117 femtofarad (fF). That’s clearly a modest dynamic range and a small step size, but it’s enough for the application. Qorvo notes that there are two ways to use capacitance to adjust the antenna appearance (Figure 4). Figure 4 Antenna tuning can be accomplished via aperture tuning or impedance tuning, each with distinct tradeoffs in attributes and capabilities. Source: Qorvo Aperture tuning optimizes the total antenna efficiency from the antenna terminal’s free space, and it can do so across multiple bands. It can provide advantages with respect to antenna efficiency for both transmit and receive communications, improving total radiated power (TRP) and total isotropic sensitivity (TIS) by 3 dB or more in some situations. Impedance tuning maximizes power transfer between the RF front-end and the antenna, and it increases the TRP and TIS by minimizing mismatch loss between the antenna and antenna front-end. It also helps to compensate for environmental effects such as a person’s hand position on a smartphone. Beyond antenna tuning According to Qorvo, “Today, aperture tuning is the primary method used in handsets to overcome reduced antenna area and efficiency. Mid-tier and higher-end smartphones use a combination of aperture and impedance tuning to support the ever-broadening range of frequency bands, especially for 5G.” These ICs are somewhat analogous to the widely used digital potentiometers (digipots), except those typically have 256 or more steps spread over a fairly wide kilohm range along with a much-larger relative step size. All this makes me wonder if commercially available digi-inductors will be coming soon as well. Beyond antenna tuning, I’d like to think that creative engineers are already looking at these parts and finding unforeseen uses for them. Historically, that’s been the reality as components which originally targeted one class of situations are soon adopted and adapted to address other problems. Perhaps these tunable pico-farad capacitors will be used to compensate for or cancel circuit parasitics in a balanced or differential topology. Or perhaps they will be used for precise calibration and measurement in some Wheatstone-bridge type of arrangement…you never know.

  • Should stock trading get high-frequency spectrum?

    Should stock trading get high-frequency spectrum? Aug 23, 2023 | 5:26 AM When I first saw the phrase “high-frequency trading” or HFT, I assumed it was an advanced engineering technique for trading off and managing spectrum use in order to increase channel capacity or improve signal-to-noise ratio (SNR). I was very wrong. Instead, it’s related to a petition to the Federal Communications Commission by Wall Street-related trading firms to allow them to use some slices of spectrum to set up “private” high-power transmitters in the high-frequency (HF) bands under 30 MHz, also traditionally called the shortwave bands. So, they can transfer stock and related pricing between cities such as Chicago and New York a few milliseconds faster than achievable using optical links. This tiny increase would allow them to “run ahead” of trades by others and take advantage of tiny price differentials to reap additional profit. This scheme has its own name, “latency arbitrage”. The petition from “Shortwave Modernization Coalition” (SMC) is assigned Docket RM-11953 and titled “Shortwave Modernization Coalition Petition for Rulemaking to Amend the Commission’s Rules to Allow Fixed, Long-Distance, Non-Voice Communications Above 2 MHz and Below 25 MHz” (be prepared: it’s 105 double-spaced pages, all text). Their petition request would potentially put 50-kHz wide, 20-kilowatt signals immediately adjacent to seven amateur-radio (ham) bands. In contrast to those power levels, amateurs are restricted by Part 90 high-frequency rules to 1,000 W peak envelope power (PEP). Even that peak-power number is somewhat misleading, as most radio amateurs operate at under 100 watts (it’s called “running barefoot”) and many are routinely under 10 watts while still achieving long-distance and even worldwide contacts. Further, SMC’s proposal would reduce the existing protection of -73 dB edge-of-band/out-of-band attenuation now in use for the 1,000-watt power limit to just -50 dB protection for their proposed 20-kW limit. This proposal includes four likely transmission scenarios: New York, NY transmitting west, such as to Los Angeles, CA Chicago, IL, transmitting west, such as to Seattle, WA New York, NY, transmitting south, such as to São Paulo, Brazil Chicago, IL, transmitting east, such as to London, UK What sort of decrease in propagation delay are we looking at? Basic physics and math show that for a typical RF-hop distance they would use, the saving between wireless atmospheric path and an optical-fiber path would be on the order of 10 milliseconds, and less in many cases. The use of radio links for stock-trading HFTs is not a new development. RF links are already used with point-to-point microwave towers linking major trading centers. However, many of these systems use microwave links where there is more available bandwidth than the high-frequency bands. Also, since they are point-to-point systems, their emitted RF energy is more limited, and the beam spread is fairly narrow. However, a long-distance microwave link takes many towers, since the tower range is generally limited to 30 to 50 miles maximum due to curvature of the Earth’s curvature and is a function of tower height (Figure 1). Figure 1 Microwave relay towers, typically spaced up to 30 to 50 miles apart and using focused beams, have minimal RF “splatter” and have only modest potential for causing adjacent-spectrum RF interference. Source: Dr Jai W. Kang Long-distance high-frequency latency arbitrage links are already in use. Unlike microwave towers, it only takes one antenna at each end of the link. However, that same link and its path are subject to all sorts of performance inconsistency issues and “skip zones.” These are a function of atmospheric propagation conditions which vary with time of day, sunspot cycles, and many other factors which can only be predicted to a linted extent (Figure 2). Moreover, the effective data rate is low, but may be enough for the HFT application. Figure 2 Long-distance RF links are subject to the vagaries of atmospheric propagation characteristics in addition to somewhat predictable changes. Source: Australian Space Weather Forecasting Centre Software engineer and ham radio operator Bob Van Valzah has identified such high-frequency antennas in his Chicago area. He has also done the deep digging through the licensing firms and layers of trading corporations which obscure ownership and operation, as detailed in his blog “Shortwave Trading | Part I | The West Chicago Tower Mystery.” This latest application is for higher power and frequency slices which may cause adjacent-channel problems. Obviously, the amateur-radio community led by its primary user association, the ARRL, has filed many objections to the proposal, pointing out the likely spillover interference and potential safety/emergency-related issues as well as day-to-day problems. There are about 760,000 amateur radio operators in the United States, according to ARRL, and while many are not active, the base number is growing. But the issue is not which side has more members or money, it’s really about the best use of the limited resource of the electromagnetic spectrum and the harm that misuse of the spectrum can do to other users and services. Keep in mind that the spectrum is an unusual resource. On the one hand, it’s limited, and you can’t make more of it. Even though the entire spectrum follows Maxwell’s equations, different parts of it have immutable attributes: compare low frequencies with terahertz ones, as one example. On the other hand, it is infinitely recyclable and using spectrum does not consume it, unlike using a tangible resource such lithium, or even helium, which dissipates into the atmosphere and then outer space and cannot be recovered once gone. In that sense, we are very fortunate that spectrum is used but not consumed. What’s your view on use of spectrum for limited-use, private links such a HFT versus broader applications? Does this spectrum allocation make sense? Is the interference risk manageable? Is it perhaps worth trying, since the decision can be reversed, and the used spectrum recovered? Or is reversal of allocation after such a large HFT investment not likely to happen, even if there are interference issues?

  • Ham radio might be able to help

    Nova Scotia Climate change is affecting telecommunications infrastructure. Ham radio might be able to help. The technology is ‘an unsung hero’ for getting messages out, one operator says September 06, 2023. As Atlantic Canada gears up for another hurricane season after a year of unprecedented disasters linked to climate change — including post-tropical storm Fiona last September — amateur radio operators say a simple technology can play a part in the response to disasters across the region. When Fiona hit Nova Scotia, it affected electrical grids and telecommunications networks, leaving some people unable to call for help. That experience in particular prompted a renewed interest in amateur radio — also known as ham radio — which allows non-professional users to send messages without requiring the internet or cell phone networks. "I think it's kind of an unsung hero in communications that gets forgotten in the noise of disaster when it comes to, 'Well, how do we get that message out?'" said John Bignell, president of the Halifax Amateur Radio Club. Ham radio operators use a special designated set of frequencies — not the regular AM or FM radio signals — to exchange messages locally or around the world. They say the technology can help Nova Scotians respond to the increasing risks of extreme weather, as climate change forces a reckoning with communications infrastructure across the country. Communications failed following Fiona When Lyle Donovan became emergency management co-ordinator for Victoria County in 2008, the municipality's emergency plan included amateur radio, drawing on the expertise of a local group. "They were an older generation, but they were active in amateur radio and we utilized them," he said. In time, that group petered out. With no operators left in the county, Donovan removed the section on amateur radio when he redid the municipality's emergency plan in 2016. "What's the point in having it in our emergency plan if we had no operators?" he remembered thinking. In the past, amateur radio held more appeal, Donovan said, but other forms of communication had become ubiquitous in the meantime, and amateur radio no longer seemed necessary. Downed utility lines and poles lie across Woodlawn Road in Dartmouth in the wake of Fiona. (Submitted by Joshawa Tyler LaVoie) More to the point, Nova Scotia and Atlantic Canada more broadly already have a highly stable radio network, Donovan said. All frontline emergency services in the province use the trunked mobile radio system, which was put in place after the SwissAir disaster in 1998. Donovan calls it "the best communications systems in the world." "So we got kind of complacent to think that we have this system, we have VHF, we have satellite telephone and of course, we still have our cell phones and not all of those systems are going to go down." Then post-tropical storm Fiona struck. The day after the storm made landfall in the province, Donovan, who is a paramedic, woke at 5 a.m. to prepare for work. Attempting to turn on the TV, he realized there was no power; turning to his phone, he found there was no cell service either. Because the local radio tower was down, local emergency services could talk to each other but couldn't send messages outside of the immediate area. Landlines weren't usable for most Nova Scotians during Fiona Cell outages during storms like Fiona will continue unless regulations improve, advocate says "That's when I knew we were in trouble," he said. Then, with communications interrupted, "Lo and behold, [there was] a cardiac arrest." The family of the victim was unable to call 911. While their neighbour was an RCMP corporal with a TMR radio, they were unable to call for help because they couldn't communicate with the wider network. Eventually, someone was able to get a message to Donovan via the local fire chief. But by then 40 minutes had passed and the victim couldn't be saved. "I have a close personal relationship with the family," he said. "We went on to discover that [medical attention] wouldn't have helped anyway, but it's just sheer fact that people were not able to call 911." In the aftermath of Fiona, Donovan said they started asking how the situation could have been avoided, and — after connecting with a longstanding amateur radio club in Halifax — started looking to amateur radio. "Somebody from my area could have called someone in the Halifax area, and they could have called 911 for us, to get emergency services rolling," he said. The Halifax Amateur Radio Club is one of the oldest amateur radio clubs in North America, dating back to 1932. Bignell first got interested in amateur radio as a teenager. He said its simplicity is part of its enduring appeal. "The ability to build your own radio and then send a message that bounces around the atmosphere and be able to talk around the world with a simple little wire, it's kind of cool," he said. But amateur radio is more than a hobby; because it doesn't require a service provider such as a telecommunications company, or extensive infrastructure, it can step in during disasters when other systems fail. This has been true with disasters in the past. Bignell said his club has played a role in every major disaster in the province going back to the Moose River mine disaster in 1936. Amateur radio has also been essential elsewhere. Amateur radio operators were instrumental in relaying messages around New Orleans after Hurricane Katrina knocked out telecommunications networks. In Mozambique, a recent series of storms has prompted the government to set up a network of amateur radio operators to help with disaster response. What Canada can learn from how the U.S. handles cell outages in hurricanes While communications infrastructure has steadily improved in the last 20 years, Bignell said amateur radio still provides an additional layer of safety. "We have some really robust systems in Nova Scotia and in Canada, but there's always that one moment where you go 'Oh this isn't going well, we need a backup,' and that's where amateur radio plays a real key role." John Bignell is president of the Halifax Amateur Radio Club. (Moira Donovan) Bignell said amateur radio also works with more modern technology through tools such as Winlink, which radio operators can use to send emails, weather reports and information bulletins over the airwaves, without internet. Amateur radio is undergoing a renaissance, Bignell said, in part because the ability to connect amateur radios to laptops and cell phones has greatly increased what it can do. That surge of interest is coming at a time when Canada is taking a closer look at the resilience of its telecommunications infrastructure. The federal government recently began a process to improve the resilience and reliability of telecommunications networks, citing disasters such as hurricanes Fiona and Dorian in Atlantic Canada, the forest fires in Alberta and B.C. in 2021, and the derecho storm that struck Ontario and Quebec in 2022. In a notice of consultation, the CRTC noted that the increasing risks posed by climate change have made it necessary to build a more robust telecommunications system. Jason Tremblay, community services officer for Radio Amateurs of Canada, a national volunteer-based network of amateur radio operators, said that the organization is pushing for amateur radio to be included in more conversations about strengthening communications systems. "Being able to work with government agencies, work with NGOs and members of the community, it's a way for us to understand what their needs are — it's a way to better our service." He said as technologies and climate conditions change, amateur radio operators are taking on new methods and challenges in disaster response. "There's been an explosion of interest from emergency managers," he said. "I think there will always be a call for amateur radio; it'll always adapt and be there." Bringing ham radio back In Victoria County, Donovan is now looking to re-introduce amateur radio to the municipality's emergency management plan, and has heard there's at least one radio operator in the county who is interested in helping out. Donovan is also hoping to bolster interest in an amateur radio club in the county. He stressed that what happened to emergency communications after Fiona was a rare occurrence. Still, he thinks amateur radio could form an additional layer, to help the public feel safe in the disasters to come. "Amateur radio is certainly still a benefit to Nova Scotia. It's a backup system, and in the event that something happens, it's something that we could use." About The Author Moira Donovan
