It’s 5 years ago today we sold the very first blue and white RSP to someone in Sweden – many thanks to all our customers over the 5 years
Perhaps it’s just because I’m getting older, but it’s hard to believe it’s been five years!
The little RSP1 really disrupted the SDR world. Up to 2014, there were few sub $150 SDRs that included HF reception natively. There were even fewer sub $150 SDRs that I would consider “enthusiast grade”–those that were sensitive, selective, and not prone to overload.
When I initially tested the RSP1 it pretty much blew my mind. I was so impressed by the performance for the price point.
Looking back at my original review, I see that I had a long list of “pros” and only three “cons.” In fact, two of the three “cons” I listed are no longer valid (multi-channel recordings are now an option and SDRplay has their own OEM application, SDRuno).
SDRplay has demonstrated iterative agility with each new product offering and built an impressive community in five years. They have also maintained their position as a price leader even though their products are all designed and manufactured in the UK.
I used an SDR and a 40 foot end-fed antenna located in a park near the Nashville, TN airport.
On the plus side I did notice a spike of AM signals and amateur radio signals especially on 40 meters. On the negative side, my AM scans were adversely affected by the nearby powerhouse WSM transmitter on 650 kHz.
I’ve attached my results in a spreadsheet [embedded] below.
Fantastic, Ivan! Thank you for taking the time to go through your recordings and make these notes. No doubt, this log took a few hours to compile. I’ve yet to go through my eclipse spectrum recordings–!
This latest video from Mike starts by showing the differences between the RSP1 and the RSP1A, and then gives an excellent demonstration of how the latest SDRuno works – this is a great place to start for any newcomers to SDRuno – https://youtu.be/qUZerxeHJvc
We continue to regularly add video guides to our Youtube Channel. The original series are listed in a playlist called ‘Part 1’ – newer guides are listed in a playlist called ‘Part 2’
Mike Ladd, with SDRplay, 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.
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. Enjoy! (And thanks again, Mike!)
Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW) who shares the following:
I finally got around to listening through some of the amateur radio band spectrum captures from the 2017 Solar Eclipse QSO party. I used an SDRPlay receiver with an end fed LNR antenna in portable field setting in Nashville, TN.
About 30 minutes of solar eclipse contacts and chatter:
Thank you, Ivan, for taking the time to put this video together and sharing it. The RSP did a fantastic job capturing this spectrum–I do love the SDRuno application for reviewing spectrum recordings as well. Cheers!
SDRplay are pleased to announce a price reduction for their entry-level SDR receiver, the RSP1 to $99.95 USD making it the most competitive mid-range SDR to include reception down to low frequencies without the need for an upconverter.
The RSP1 provides general coverage receiver and panadapter capability from 10 kHz to 2 GHz. As well as providing SDRuno SDR software, support for popular 3rd party packages like HDSDR, SDR-Console and Cubic SDR is provided. Recent availability of an SD Card image makes for easy set up on a Raspberry Pi.
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.
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!
