Receiving Jupiter with the SDRplay RSP1

I’ve been fascinated with radio astronomy since my university days. In the 1980s and 90s almost any radio astronomy experiment equated to forking out some serious money to purchase a wideband receiver (serious money to a student, at least). With the advent of SDRs, though, radio astronomy has become affordable for everyone.

Many thanks to RTL-SDR.com for publishing the following video and post about monitoring Jupiter radio bursts:

Over on YouTube user MaskitolSAE has uploaded a video showing him receiving some noise bursts from Jupiter with his SDRplay RSP1. The planet Jupiter is known to emit bursts of noise via natural ‘radio lasers’ powered partly by the planets interaction with the electrically conductive gases emitted by Io, one of the the planets moons. When Jupiter is high in the sky and the Earth passes through one of these radio lasers the noise bursts can be received on Earth quite easily with an appropriate antenna

In his video MaskitolSAE shows the 10 MHz of waterfall and audio from some Jupiter noise bursts received with his SDRplay RSP1 at 22119 kHz. According to the YouTube description, it appears that he is using the UTR-2 radio telescope which is a large Ukrainian radio telescope installation that consists of an array of 2040 dipoles. A professional radio telescope installation is not required to receive the Jupiter bursts (a backyard dipole tuned to ~20 MHz will work), but the professional radio telescope does get some really nice strong bursts as seen in the video.

As Carl mentions above, you do not need a professional radio telescope to receive Jupiter noise bursts, a dipole will do.

In fact, the Pisgah Astronomical Research Institute (PARI) has a dedicated Jupiter receiver–a simple SDR kit called the Radio JOVE Receiver which is promoted by NASA. While PARI has the resources to install any number of antennas, PARI uses two simple dipoles which are mounted only a few feet off the ground as their radio telescope. I doubt their investment in the antennas exceeded $50. It works brilliantly.

The Radio JOVE receiver at PARI

I had planned to purchase and build a JOVE receiver (and, for fun, still may!), but it would be much easier to simply use the SDRplay RSP I already have in my shack. What a great project this fall.

Post readers: Please comment if you’ve used an SDR or JOVE kit to receive Jupiter bursts!

Raspberry Pi image with preloaded SDRplay RSP software

The $35 Raspberry Pi 3

SDRplay support have just posted the following news on their community forum:

We 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 receiver

Please 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.


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:

http://www.sdrplay.com/software/SDRplay_RPi3_V0.1.zip (2.7 GB)

http://www.sdrplay.com/software/SDRplay … 0.1.img.7z (2.0 GB)

2. Extract the contents of the compressed file. This will extract to a .img file which will be about 7.2 GB

3. Use an image writer such as Win32DiskImager (https://sourceforge.net/projects/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 Support

This 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 to follow this thread, and the forum in general, 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:

Mike’s SDRuno tutorial videos for the SDRplay RSP series

Many thanks to SWLing Post contributor, Mike Ladd (with SDRplay) who notes that he has been working on a series of tutorials for operating the SDRuno.

In the past week, I’ve had no less than two readers ask about tutorial resources for SDRuno, and the RSP series software defined radios, so Mike’s message is timely.

So far, Mike has covered the following topics (click link to watch video):

  1. Basic layout and settings
  2. SDRuno with VAC (part 1)
  3. SDRuno with VAC (part 2)
  4. SDRuno Noise Reduction
  5. Memory Panel (part 1)
  6. Memory Panel (part 2)
  7. RSP1 and RSP 2 calibration
  8. SDRuno VAC & DSDdecoder

Mike’s videos are very clear and comprehensive. For example, check out his first video which outlines SDRuno layout and basic settings:

Mike is continuously adding new tutorial videos, so check out the full updated playlist on YouTube.

Great job, Mike!

ADS-B for SDRplay RSP1 and RSP2 now available

I was very happy to see the following message from Jon Hudson at SDRplay this morning:

“ADS-B for both RSP1 and RSP2 is now available for the Raspberry Pi 2 & 3 – you can get the software from downloads – http://www.sdrplay.com/downloads

If you are an RSP2 user, make sure you use Antenna Port B when running ADS-B.”

This is great news as I’ve had a number of readers ask if the RSP series SDR was compatible with the DUMP1090 ADS-B system.

The SDRplay RSP2

If you have an RSP1 or RSP2 and either a Raspberry Pi 2 or Pi 3, this will be an easy, accessible way to experiment with ADS-B.

In the long run, however, I’d never devote an RSP as a dedicated ADS-B feeder. Why? The RSP is a very versatile, full-featured SDR and I wouldn’t want to tie it up with such a relatively routine, simple task.

Instead, I’d give ADS-B a try with the RSP, and if I liked it, I’d purchase this inexpensive FlightAware RTL-SDR dongle with a built-in 1090 MHz bandpass filter for $18.95.

Click here to read my recent article about setting up a FlightAware ADS-B feeder.

I’m always so happy to see such active application development from “Mom and Pop” companies like SDRplay and AirSpy. Just more ways to put your SDR to work for you!

SDRplay RSP-1 OEM Metal Case

Many thanks to SWLing Post contributor, Rafman, who writes:

The SDRplay RSP-1 OEM Metal case is ready for order and shipment Worldwide


  • 1x Black aluminum metal enclosure with two labeled side panels, 1x Broadcast FM band-stop filter plus SMA Male to SMA Male barrel adapter,
  • 1x Black semi-hardshell carry case,
  • 1x Thermal pad to keep the RSP-1 cool and mechanically stable inside the enclosure and
  • 1x Accessory set including enclosure screws, GND lug bolt set and 3M anti-slip rubber feet.
    Can be used to upgrade the SDRplay RSP-1 ONLY to a metal enclosure. Helps block RF interference.

Note that owners of the very first RSP-1’s with F-Type connectors may require an additional F-Type pigtail adapter, or a MMCX to SMA pigtail to be able to use the BCFM filter internally. The BCFM filter can still be used externally.

Click here to view the RSP-1 metal case at Amazon.com (availability expected March 27).

Thank you, Rafman! I have the first generation RSP-1, so appreciate the note about using the filter internally via an adapter. That’s a nice enclosure.
