The $22 RTL-SDR paired with a Raspberry Pi and employed as an ADS-B receiver/feeder.The following article originally appeared in the:Welcome back to the world of SDRsof our three-part primer on software-defined radios (SDRs). While last month’s focused on the nomenclature and components of a functioning SDR system, Part Two will take a look at some affordable SDR station options that will propel you into the world of SDRs for less than $200 US., and we’ll dive a little deeper into the rabbit hole and cover higher-end SDRs and ham radio transceivers with embedded SDRs. SDRs are affordableIf there’s one thing I’d like you to take away from this part of our primer, it’s that SDRs are truly affordable. For less than the price of a typical full-featured shortwave portable, you can own an SDR that covers almost all of the listening spectrum, and that does so with excellent performance characteristics.We’re lucky to live in a time of phenomenal radio innovation. When I first jumped into the world of SDRs, the least expensive SDR that covered any of the bands below 20 MHz was about $500. That was only a few years ago, in 2010 or so.Yet in the past three years, affordable SDRs have become the dominant radio product on the market. And these modestly-priced products have made the barrier of entry into the SDR world crumble overnight.Today, even a $100 SDR has more features, more frequency range, and more functionality than a $1000 SDR from just a decade ago.
Times have changed dramatically; indeed, the pace of innovation in this craft is simply amazing.Before we begin looking at some choice sub-$200 SDRs, I’d just like to direct your attention to the first part of our SDR Primer. Specifically, I’d like you to note one element I discussed in that article: the vital importance identifying your goals as an SDR owner. In other words, how do you plan to use your SDR? If you’re only seeking an SDR to listen to local ham radio repeaters, track cubesat satellites, or gather ADS-B information from aircraft, a $25 SDR will more than suffice.

If you wish to use the SDR as a transceiver panadapter, or you wish to chase weak signal DX on the HF bands, then I’d suggest you invest a bit more.I’d also like to remind you, as I noted in the previous article, that this primer will be limited in the SDRs I highlight. The reason for this is simple: there now exists a vast ocean of SDRs on the market (just search eBay for “SDR” and you’ll quickly see what I mean) so all models simply can’t be included in this introductory foray. I’ll be focusing here on several SDRs that cover the HF spectrum and above. I’ll also focus on SDRs with which I have personal experience, and which I consider to be “enthusiast” grade among a healthy community of users.
Of course, this part of the primer will only include HF-capable receivers that cost a total of $200 or less.Let’s take a look at what’s on the market in order of price, starting with the most affordable. $10-$25: The RTL-SDR dongleNo doubt, many of you reading this primer have purchased an RTL-SDR dongle. Over the years, I’ve owned three or four of them and have even purchased them for friends. These dongles originally appeared on the market many years ago as mass-produced DVB-T TV tuner dongles based on the RTL2832U chipset. Very soon, users discovered that with just a little hacking, the dongle was capable of much, much more than its original intended purpose.The dongle resembles a USB memory stick. On one end, you’ll find a standard USB connector. On the other, you’ll find an antenna port, typically SMA, to which one connects an antenna.
Although it goes without saying, here’s a friendly reminder: make sure you’re choosing an antenna to match the frequency range you’re exploring! I’ve seen this older model of RTL-SDR being sold for $9 at Hamvention.Early RTL-SDR dongles couldn’t cover the HF bands or lower, but many models can now cover a gapless 500 kHz all the way to 1.75 GHz.So, what can you do with an RTL-SDR dongle? In short, quite a lot! Here are a few of this simple device’s many applications and uses in our hobby. It can:.
become a police radio scanner. monitor aircraft and ATC communications.
track aircraft with ADS-B decoding and read ACARS short messages. scan trunking radio conversations. decode unencrypted digital voice transmissions such as P25/DMR/D-STAR. track maritime boat positions like a radar with AIS decoding.
track and receive weather balloon data. connect to VHF amateur radio. decode APRS packets.
receive and decode GPS signals. utilize its rtl-sdr as a spectrum analyzer. receive NOAA weather satellite images. and so much more––! This list is not fully comprehensive by any means.And, of course, you can listen to any signals between 500 kHz up to 1.75 GHz––essentially, most of the radio listening landscape.Is $25 still a little high for your budget?
RTL-SDR dongles. While the cheapest of these dongles may suffice for some radio applications, I’m partial to, since they’re built in a tough metal enclosure, have thermal pad cooling, as well as extra ESD protection. Amazon has an RTL-SDR.com dongle starter package with antenna options. That’s, what, the price of three hamburgers? Two orders of fish and chips?
And worth it.Many third-party SDR applications support the RTL-SDR dongle, but my favorite is SDR#.So, the major pros of this little SDR are 1) obviously, the price; 2) many, many uses; and 3) the fact that it’s the most popular SDR on the market, with a massive online user base.What about negatives? Well, to be frank––aside from the dongle’s budget-busting versatility––the fact is that “you pay for what you get.” You’re investing just $10-$27 in this receiver, so don’t expect exceptional performance especially on anything lower than 50 MHz. On HF, for example, the RTL-SDR could easily overload unless you employ external filtering.Indeed, I’ve never used the RTL-SDR for HF DXing, but I currently have three dongles in service 24/7: two as, and one as a receiver for the network. And these work hard. Indeed, It’s a workhorse of a device!I suggest you grab an RTL-SDR and use it as an accessible step into the world of SDRs, and as an affordable single-purpose tool to unlock the RF spectrum!$99: The SDRplay RSP1AWhen you invest a modest $99 US (or $120 shipped), and purchase the RSP1A, you take a major step forward in the SDR world.UK-based is an SDR designer and manufacturer that focuses on enthusiast-grade, budget wideband SDRs.
SDRplay designs and manufactures all of their SDRs in the United Kingdom, and over the past few years, they’ve developed a robust user community, extensive documentation, and, in my humble opinion,. SDRuno windows can be arranged a number of ways on your monitor.Although the RSP series SDRs are supported by most third-party SDR applications, SDRplay has their own app: SDRuno. Moreover, SDRuno is a full-featured, customizable application that takes advantages of all of this SDR’s performance potential and features. I should mention that installing the RSP1A and SDRuno is a pure plug-and-play experience: just download and install the application, plug in the RSP1A to your computer, wait for the USB driver to automatically install, then start SDRuno.
Simplicity itself.While the RSP1A is SDRplay’s entry-level wideband SDR, it nonetheless plays like a pro receiver and truly pushes the envelope of performance-for-price, and for other SDR manufacturers, sets the bar quite high. The RSP1A is a wideband receiver that covers from 1 kHz all the way to 2 GHz; equally pleasing the longwave DXer, HF hound, tropo-scatter hunter, and even radio astronomer. This affordable SDR really covers the spectrum, quite literally. Not only does the RSP1A cover a vast frequency range, but its working bandwidth can be an impressive 10 MHz wide and via SDRuno, the RSP1A will support up to 16 individual receivers in any 10 MHz slice of spectrum. All this for $99?
I assure you, yes.Think of the RSP1A as the sporty-but-affordable compact car of the SDR world. It delivers performance well above its comparatively modest price, and is fun to operate. The SDRplay RSP2 ProIn 2016, after the remarkable success of the original RSP, SDRplay introduced the RSP2 and RSP2 Pro SDRs. The RSP2 is housed in an RF-shielded robust plastic case and the RSP2 Pro is enclosed in a rugged black painted steel case.
In terms of receivers and features, the RSP2 and RSP2 Pro are otherwise identicalThe RSP2 and RSP2 Pro provide excellent performance, three software-selectable antenna inputs, and clocking features, all of which lend it to amateur radio, industrial, scientific, and educational applications; it is a sweet SDR for $169 or $199 (Pro version). I know of no other SDRs with this set of features at this price point.The RSP2 series has the same frequency coverage as the RSP1A. Of course, to most of us, the big upgrade from the SDRplay RSP1A is the RSP2’s multiple antenna ports: 2 x 50-Ohms and one High-Z port for lower frequencies. The SDRplay RSP2 with plastic enclosure.As with all of SDRplay’s SDRs, their own application, SDRuno, will support up to 16 individual receivers in any 10 MHz slice of spectrum.Bottom line? Since the RSP2 has multiple antenna ports––and two antenna options for HF frequencies and below–the RSP2 is my choice sub-$200 SDR to use as a transceiver panadapter.
(Spoiler alert: you’ll also want to check out our summary of the recently released $279 RSPduo from SDRplay or in Part 3 of our primer before pulling the trigger on the purchase of an RSP2 or, especially, an RSP2 Pro!)Check out the RSP2 via:.$199 US: AirSpy HF+Sometimes big surprises come in small packages. That pretty much sums up the imminently pocketable AirSpy HF+ SDR.The HF+ has the footprint of a typical business card, and is about as thick as a smartphone.
Despite this, it’s a heavy little receiver––no doubt due to its metal alloy case/enclosure. The HF port is labeled as “H” and the VHF port as “V”When I first put it on the air, my expectations were low. But I quickly discovered that the HF+ belies its size, and is truly one of the hottest sub $500 receivers on the market! Its HF performance is nothing short of phenomenal.The HF+ is not a wideband receiver like the FunCube Dongle Pro+ or RSP series by SDRplay. Rather, the HF+ covers between 9 kHz to 31 MHz and from 60 to 260 MHz only; while this is a relatively small portion of the spectrum when compared with its competitors, this was a strategic choice by AirSpy. As AirSpy’s president, Youssef Touil, told me, “The main purpose of the HF+ is to have the best possible performance on HF at an affordable price.”Mission accomplished.
Like other SDRs, the HF+ uses high dynamic range ADCs and front-ends but enhances the receiver’s frequency agility by using high-performance passive mixers with a robust polyphase harmonic rejection structure. The HF+ was designed for a high dynamic range, thus it is the best sub-$200 I’ve tested for strong signal handling capability on the HF bands.You can very easily experiment and customize the HF+ as well; allows you to make one of several published modifications. The AirSpy application (a.k.a.
SDR#)Installing the HF+ and getting it on the air is pure plug-and-play. While SDR# is a powerful and fluid SDR application, I actually use more often, as it supports most of my other SDRs as well, and offers.If you’re an HF guy like me, the HF+ will be a welcome addition to your receiver arsenal. It’s a steal at $200.ConclusionIf you haven’t gathered this already, it’s simply a brilliant time to be a budget-minded radio enthusiast. Only a few years ago, there were few, if any, enthusiast-grade sub-$200 SDR options on the market. Now there are quite a number, and their performance characteristics are likely to impress even the hardest-core weak-signal DXer.Still, some hams and SW listeners reading this article will no doubt live in a tougher RF environment where built-in hardware filters are requisite to prevent your receiver from overloading. Or perhaps you desire truly uncompromising benchmark performance from your SDR.
If either is the case, you may need to invest a little more of your radio funds in an SDR to get exactly what you wantand that’s exactly where I’ll take you November in the final Part Three of this SDR primer series. Stay tuned!Stay tuned for more in Part Three (November). I’ll add links here after publication.

A few weeks ago, we posted that spectrum analyzer software was being developed for the SDRplay RSP software defined radio series. Many thanks to Andy, at, who shares the following announcement:We are pleased to announce the availability of the first cut of Spectrum Analyser software developed by Steve Andrew specifically for the RSP line of products. Please note that this is first alpha software and so it is still very much in development and some features are still to be added.
Currently supported are:. RSP1. RSP2/RSP2pro. RSP1AThis first alpha release gives a good idea as to the look and feel for the software.
The main functional limitation is that sweeps of greater than 10 MHz are not currently supported. Steve is currently re-working the algorithms for providing wider sweeps than 10 MHz to improve sweep time and remove the issue of the DC spike in ZIF mode, so please bear with him.We recommend using the software with AGC turned off and use manual control of the gain for better display stability.Please see the Spectrum Analyser webpage:Best regards,SDRplay Support. The SDRplay RSP2Mike Ladd, with, has done an amazing job putting together a comprehensive series of how-to videos for those of us with the SDRplay RSP1 and RSP2 receivers. His first set of videos have focused on using SDRuno (SDRplay’s custom SDR application), and now he’s started an SDR Console series as well.I’ve embedded much of his video series below, but you can also find them at.If you own an SDRplay RSP, take time to watch some or all of these videos as they’ll help you unlock RSP functionality you likely never knew existed. I’ve learned something new in each one I’ve watched.Below, I’ve embedded 23 SDRuno how-to videos, a new SDR Console video and PDF/printable SDRplay documentation. The $35 Raspberry Pi 3SDRplay support have just posted the following newsWe have released a Raspberry Pi 3 image that has a number of SDR applications pre-built and tested that support the RSP.
Periodically, we will update the image with software updates and new software.The current list of software included on the image is:SoapySDR/SoapySDRPlay, SoapyRemote, ADS-B (dump1090), CubicSDR and SDR-J DAB receiverPlease note: This is a complete OS with software image. Writing the image to a micro SD card will wipe the micro SD card of any other data that is on there, so we recommend you make sure you have backed up any data on your existing micro SD card or you use a new micro SD card.Instructions:1. Download image. There are two downloads provided, the 7zip version is just a smaller download but not everyone has 7zip which is why we also provide a zip download. The links are here:(2.7 GB)(2.0 GB)2. Extract the contents of the compressed file. This will extract to a.img file which will be about 7.2 GB3.
Use an image writer such as Win32DiskImager to put the image onto the micro SD card.WARNING: Please make sure that you use the correct drive letter for the micro SD card. The image writing software will completely remove any data that is on the destination media.That’s it – put the micro SD card into the Raspberry Pi 3 micro SD card slot and boot the system. Allow the system to fully boot and you will see a GUI that will allow you to run each of the applications or read further information.We also recommend that you use an active cooling system on your Raspberry Pi 3 to avoid any issues with over heating. In our tests, we have used heatsinks and a fan in a case.
The CPU speed will be throttled if the temperature gets too hot, so for optimum use this is really recommended. These cases are available at reasonable prices from many Raspberry Pi stores.If you are a developer of software that supports the RSP and you would like to be included on the image that we will release periodically, please contact us at software@sdrplay.com – currently we’re aiming to update the image every quarter, this will largely depend on software availability and what the demand is.We are aware of other software that we are looking to get onto the next release such as Pothos and more SDR-J software. We will work with developers on any issues we’ve seen during this process so that we can get them onto future images.Best regards,SDRplay SupportThis is great news in my book, because a fully-loaded and configured disk image makes it much easier to get started with an RSP/Pi combo.Note that the message above is merely the announcement on SDRplay’s community forum. I would strongly encourage you, if you’re interested in updates and announcements.Raspberry Pi systems are very affordable and available in a number of configurations (from $35US – $80US depending on accessories) and from a number of retailers including:.
