Announcing The SDRPlay RSP2 & RSP2pro.



It was back in August 2014 that SDRPlay launched the RSP1, a wide range SDR, covering 10kHz to 2GHz. It has sold 1000's of units world wide, and has become the goto SDR in the sub $200 price range. Accompanied by the amazing SDRUno Software, it is the complete package.

Well now SDRPlay have announced the RSP2 and RSP2pro an upgrade to the RSP1, many enhancements that users have been asking for.

Built in MW/FM Notch Filters
Improved Band Filtering and Extra Band Filters
0.5ppm TXCO
3 Antenna Connectors 2x  SMA(PortA/B) 1x HiZ
24mhz Reference Clock In/Out
RSP2 - Metalized Plastic Case
RSP2pro - Metal Case
4.7V Bias-T on Antenna PortB Switchable

 

So as many of you may know, I'm a Beta Tester for SDRPlay, and we've been testing the RSP2 for a few months now, comparing it against the RSP1, I've had a few versions with hardware upgrades along the way as we tested (Mike & Preben were in on the secret too). Switching between the RSP1 and RSP2 comparing signals on various antennas. This post is just to wet your appetite, more to come....

Let me start by just saying WOW, SDRPlay hit this one out of the park. They took on user comments about the RSP1 and have applied them to the new version.

So where to start,

Antenna Ports
Gone is the single SMA connector, replaced with Dual SMA Connectors, and a Plug-able 3 screw connector for the HiZ port. The SMA ports are slightly different, Port A is a normal antenna port as on the RSP1, Port B lets you enable the Bias-T, so it's recommended that you use Port A for your general listening on all bands, and if you have an external LNA that requires power for VHF/UHF etc, then use Port B. the Bias-T is turned on in the software.

I've been concentrating on comparing Port A and the HiZ Port, SDRPlay recommend the HiZ port for HF listening, and I can tell you, they are not wrong, the performance on HF via the HiZ port is just amazing. I have just the long wire running to the P connection and my station Ground connected to the GND pin, I have left the N disconnected, but SDRPlay also say you can connect a small loop from N t the GND pin, I personally didn't see any difference when I did. I also connected my 160m ladderline fed antenna to the P and N and it performed flawlessly. 

Port A worked just as good when fed with the long wire, gain settings were slightly different from the HiZ connections, but once you have them set, it's fairly easy then swapping the antennas over, and the signal remaining the same.

Port B works as port A, but also has the 4.7V @ 100mA Bias-T available to power an external LNA via the coax feed, this is enabled in the software (SDRUno V1.1)

On the opposite end of the case are the 24MHz Reference Clock In/Out ports, these allow for multiple RSP2's to be clock synced for diversity reception and more. These are MCX connectors.

Notch Filters

SO this is a biggie, the RSP2 now includes a MW/FM Notch filter, and it works very well....

Port A - No Notch Applied

Port A - New Notch Filter Applied

There is just one button that applies the notch filters, when applied the MW(AM) and FM Broadcast filters are both applied, I saw some spurs on HF from the local AM power houses, but as soon as the filter was applied, all the spurs vanished and HF was clean as a whistle. Also the RSP1 suffered from Broadcast FM images in the 380Mhz area, these are now a thing of the past, even without the Notch Applied, the notch just makes doubly sure.

TCXO

The RSP2 now includes a 0.5ppm TCXO, the unit is VERY stable, you can still adjust the PPM down to 0.01ppm, and SDRUno V1.1 will auto calibrate this for you if you tune to WWV or another accurate source, tune in SAM mode and then go to RX/SETT/CAL and hit Auto CAL, it will them set your PPM, once set, it is ultra stable, I have had one of my Pro's running for several days and virtually NO drift at all.

Cases

The RSP2 comes in two versions, The RSP2 and the RSP2pro, so what are the differences, well it's just cosmetic, the internal workings are the same, the RSP2 comes in a Black Plastic Case, the difference from the RSP1 is the case has a metallic coating on the inside of the case, giving it adequate shielding from the outside world of RF.

The RSP2Pro comes in a rugged metal case, it still offers the same amount of shielding, and during testing, no real difference was noticeable, the metal case is heavier and is intended for a professional environment, or so the guys at SDRPlay tell me.... I just love the metal case, but again I think you will need a very expensive piece of test equipment to see any difference between the two versions of case, my eyes and ears certainly can't see it...

 

A more in depth review will be added soon, we've just finished the testing, now we get to play with it....
It's an AMAZING box, and a MAJOR step up from the RSP1, It's so good I have 3 of them at the moment, one is a early beta, but it works, and 2 RSP2pro's, do I want more...YESSSSSS

13 Colonies Station K2L, So over the July 4th weekend, I operated as part of the K2L team for the 13 Colonies Special Event, we put South Carolina on the air as one of the original 13 colonies, this is the 8th year of operation, and the event is getting bigger, this year our total contact count was down, as SC K2L we made 13,811 contacts with stations in the USA and Around the world. K2L made the most contacts as state, and we achieved TOP STATE again, this is the 3rd year we have done this. In total, all 13 colonies made a total of 139,772 contacts, up from 126,296 in 2015. The event is getting larger every year, for more info on the event visit www.13colonies.net I would like to thank all of my K2L operators, Doug, Brian, Frank, Ariel, Bill, Loyd, Tom, together the 8 of us made a great team.

At 0800 UTC this morning SDRPlay released the amazing SDRuno software, it's aimed at the SDRPlay RSP, but will operate other SDR's with limited functionality. And see my SDRUno Guide on the menu above...after several weeks of testingf the public can now access this great software for use with thier SDRPlay RSP SDR, and amazingly, It's FREE, yes FREE... 

SDRUno running 4 Virtual Receivers 

Official Press Release...
 

SDRplay is pleased to announce the official release of SDRuno for the RSP. SDRuno is the new name for the RSP compatible version of Studio1, the rights to which we obtained and announced on 28th April. SDRuno contains native support for the SDRplay RSP and no extra plugins are required. Third party hardware can also be supported via the ExtIO interface, but with reduced functionality.
SDRuno provides a rugged and flexible, high performance SDR receiver capability and boasts some excellent features:
• Multiple ‘Virtual Receivers’ which allow for simultaneous reception and demodulation of different types of signals within the same receiver bandwidth.
• A selectivity filter with an ultimate rejection greater than 140 dB.
• A unique distortion-free double stage AGC with fully adjustable parameters.
• Multiple notch filters with BW adjustable down to 1 Hz, Notch Lock feature.
• A unique synchronous AM mode with selectable/adjustable sidebands, dedicated PLL input filter, and selectable PLL time constants.
• SNR (stereo noise reduction), featuring a proprietary noise reduction algorithm for stereo broadcast.
• AFC for FM signals.
• Calibration for receiver frequency errors.
Over time, we plan to add many more features to SDRuno to enhance the user’s experience of this very powerful piece of software. This software runs on Windows and we don’t yet know how easy it will be to migrate it to other platforms but this is something we will be investigating.
SDRuno will be made freely available to all current and future users of the RSP – to download a copy – simply go to http://www.sdrplay.com/windows.html
Our support for SDRuno in no way lessens our commitment to support HDSDR, SDR Console, Cubic SDR or ANY other software solution where the authors are willing to work with us. We fully recognise that many people have strong preferences for particular pieces of software and we do not want to do anything to undermine the options that people have to use their favoured software packages. Indeed, our view is quite the opposite. Our objective remains aim to have our hardware platforms support any and every SDR package out there. This of course may not be possible, but it is our philosophy and part of the ethos of our company.
About Studio 1:
Studio1 was developed in Italy by SDR Applications S.a.s. and has hundreds of happy customers around the world.
Studio 1 is known for its user friendly stylish GUI, CPU efficiency and advanced DSP capabilities, including features not

Sdruno in final testing

User Rating: 0 / 5

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

So tonight I received the final pre-release beta for SDRuno, the software package from SDRPlay for use with their RSP1. Full public release should be this week, or Monday at the latest.

 

It works very well, as you would expect coming from Studio1, it has changes made by the SDRPlay team to use the RSP to it's full extent, those are the changes we have been testing for the past two weeks. We found a few bugs, but nothing major. 

 

It has a few things that need to be tweaked over the coming releases, like AM Bandwidth needs to be able to be increased, to name but one, at the moment 11Khz is the max AM bandwidth, which is more than plenty for most AM Broadcast stations, but the Chinese do insist on broadcasting at 20khz at sometimes...

 

 

 

All the windows are modular, so you can have open just what you need, here you see the Main, The RX, Memory, then below is the SP1 Spectrum and the SP2 Audio Spectrum windows, not visible are the RSP window, the EXW Extra Controls and the config windows.

 

Running SDRPlay/SDRuno/WSJT-X for JT65 Decode on 30m with a 65ft Wire (yes wsjt-x frequency is wrong)

 

I'll do a full review once the program is released along with a in-depth how to document.

Sdrplay - SDR1- DRM

User Rating: 0 / 5

Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive

So making some tests, still trying to find any bugs in the new SDR1 software, found a DRM station on 11.864Mhz (Radio Romania) decoded perfectly even with a weak signal, tried same under HDSDR and no decode, also tried SDR-Console V3 and that did manage to decode. The Audio quality in SDR1 is pretty amazing.

 

 

 

SDR1 is under test right now, SDRPlay are looking for a June release.
