Video Showing How to Decode Meteor M2 with an SDRPlay in Windows

Thanks to "Lolo sdr" for submitting his videos that show his process for receiving and decoding Meteor M2 weather satellite images in Windows with an SDRplay and SDR-Console V3. Since the SDRplay is not supported by SDR#, it is not possible to use Vasilli's excellent Meteor Demodulator plugin (site in Russian, please use the Google Translate option) which is only available for SDR#.

Lolo's method gets around this limitation by initially recording an IQ file of the satellite pass in SDR-Console V3, then opening that IQ file in SDR# via the Fileplayer plugin, which is also by Vasilli and available here. The process is a bit of extra work, and the image isn't live, but the image comes out clearly in the end.

The videos are shown below, and subtitles are available in English, French and Italian via the YouTube player options.

World Radio TV Handbook (WRTH) Reviews the SDRplay RSPDuo

A couple of days ago we ran a post noting that the Airspy HF+ WRTH review was now available for public viewing. Now thanks to Jon Hudson of SDRplay for letting us know that the SDRplay RSPDuo review from WRTH has also been released for public viewing (pdf). The SDRplay RSP Duo is a 14-bit dual tuner software defined radio that is capable of tuning between 1 kHz - 2 GHz, with two separate 2 MHz bandwidths tuned to anywhere within that frequency range.

The review provides an overview of the RSPduo noting it's various features and discussing the SDRuno software. They also note that diversity reception would be an excellent application for a dual tuner SDR, but SDRuno does not support this feature as of yet. In their tests they also mention how they found very few overloading problems.

Jon would also like to note that the pricing in the review is incorrect. The RSPduo is US$279.95, and right now there is a seasonal $50 discount for US customers at HRO.

Reviews and Assembly Videos of our SDRplay RSP1A Metal Enclosure Upgrade Set

Over on YouTube we've seen several reviews and installation videos of our SDRplay RSP1A metal enclosure + portable antenna set that we released for sale back in July of this year. The set comes with a metal enclosure, carry case, and a bonus 7m portable wire antenna spool and telescopic antenna. It costs US$29.95 including shipping and is available on our store or via Amazon.

The first review is by Tysonpower. His review is in German, but English subtitles are available on YouTube. In the review he notes that interference appears to be reduced with the metal case, and notes that the SDR is better protected against bumps.

We've also seen a review by Danny Shortwave And Radio DX which also shows the assembly process and shows how easy it is to transfer the PCB from the plastic case to the metal case.

Receiving GOES Weather Satellite HRIT with an SDRplay and 2.4 GHz WiFi Grid Antenna

Over on the SDRplay forums member RSP2user has posted a new tutorial, this time showing how to receive weather satellite images from GOES satellites with an RSP2 and cheap 2.4 GHz WiFi grid antenna

GOES 15/16/17 are geosynchronous weather satellites that beam back high resolution weather  images and data. In particular they send beautiful high resolution 'full disk' images which show one side of the entire earth. As the satellites are in geosynchronous orbit, they are quite a bit further away from the earth. So compared to the more easily receivable low earth orbit satellites such as the NOAA APT and Meteor M2 LRPT satellites, a dish antenna, good LNA and possibly a filter is required to receive them. However fortunately, as they are in a geosynchronous orbit, the satellite is in the same position in the sky all the time, so no tracking hardware is required.

In the tutorial RSP2user notes that he's been using a $16 2.4 GHz WiFi grid dish antenna and the NooElec SAWbird LNA. In the past we've also seen GOES reception from Pieter Noordhuis who used a 1.9 GHz grid antenna from L-Com which seems to be a better match to the 1.7 GHz GOES frequency. However, 2.4 GHz WiFi grid antennas are much more common and therefore much cheaper. In the past there has been debate on whether or not these cheaper WiFi antennas would be good enough for GOES, so it's good to see that the cheaper option is confirmed to work, at least for the satellite elevations found in the RSP2user's part of the USA.

The SAWBird is a 1.7 GHz LNA which is required to improve SNR by reducing system noise figure, and to filter any interfering out of band signals. The SAWbird is currently not available for public sale, but NooElec have noted that it is due to be released soon. RSP2user also notes that the polarization of the dish is important, so the dish may need to be rotated, and also that flipping the secondary reflector significantly increases the gain at 1.69 GHz.

For software the XRIT demodulator from USA-Satcom for a small fee is used together with the SDRplay RSP2. As seen by Pieter Noordhuis' results, it's also possible to receive these signals with an RTL-SDR and Pieters free software. So it may be possible to reduce the costs of a GOES reception system by using an RTL-SDR, SAWBird and 2.4 GHZ WiFi grid antenna. With those components the total cost would be well under $100.

As a bonus, in later posts on his forum thread, RSP2user shows that the system can also be used to receive HRPT images from the low earth orbit NOAA 19 satellite by hand tracking the antenna as the satellite passes over.

RadCom Review of the RSPduo Now Available Online

In the July 2018 edition of the UK based amateur radio magazine 'RadCom' Mike Richards wrote up a review of the RSPduo. This review is now available for free to download from SDRplay (pdf). The RSPduo is the latest product from SDRplay. Unlike previous models the RSPduo has two tuners on board which can be used to tune to two independent 2 MHz wide areas of the spectrum simultaneously. It currently retails for US $279.95 + shipping.

Mike's review goes over the design of the RSPduo and discusses it's dual tuning capabilities. He mentions that the most exciting prospect of the RSPduo is going to be the phase-coherent applications, such as active noise cancelling. At the moment no software for these applications is available, however SDRplay is working on it. In addition to this, Mike also discusses the new API, changes to the filtering and connections, and well as some notes on sample rates and decimation.

Detecting The Sound of Bats with a Piezo Speaker and SDRplay RSP1A

Over on YouTube user Jan de Jong has uploaded a few screenshots and sounds on a video which shows that he was able to receive the ultrasonic sound of bats by connecting a small piezo speaker to an SDRplay RSP1A.

The piezo speaker used in reverse as a microphone appears to pickup bat echolocation sound waves which are typically between 20 to 200 kHz. The piezo is resonant in the 40 - 55 kHz range and converts sounds from that range into electric pulses that can be received directly by the RSP1A.

New Store Products: SDRplay RSP1A Metal Case Upgrade + Portable Antenna Set

Over on our store we've just released two new products for sale. The first is a metal case upgrade kit for the SDRplay RSP1A. It is similar to the previous enclosure that we sold for the RSP1, but no longer comes with an included BCFM filter since the RSP1A has this filter built in as a software switchable option.

Instead we've included a portable 7 meter (23 feet) long wire antenna spool (Tecsun AN-03L) with SMA adapter, and an 11 cm to 48 cm adjustable SMA telescopic antenna. The 7 meter antenna is great for HF SWLing, and neatly rolls up into the spool for travelling. The telescopic antenna is a portable VHF/UHF antenna that can plug directly into the SMA port of the RSP1A. Both antennas fit neatly into the supplied semi-hardshell carry case. The set costs US$29.95 including shipping and is available on our store, and will be on US Amazon in a couple of weeks.

The second product is the portable antenna set just by itself. The set includes the 7m Tecsun AN-03L antenna spool, the mono plug to SMA adapter and the 11 cm to 48 cm telescopic antenna. It can be used on any SDR with SMA ports. The set costs US$11.95 and is also available on our store. It will also be on Amazon in a couple of weeks.
