SDRplay announce new networked SDR receiver

SDRplay are well known for their range of popular SDR receivers which cover all the radio bands up to 2 GHz. They have now just announced a new SDRplay nRSP-ST model which can be networked and is intended for remote operation.

The SDRplay nRSP-ST is a 14-bit ADC wideband SDR receiver covers all frequencies from 1kHz to 2GHz, with no gaps. It can remotely monitor up to 10MHz of spectrum at a time from a choice of 3 antennas.

The release price is in the region of $500 which is about double some of their other current models. It is expected that it will be available to purchase towards the end of 2024.

Analysis... This is an interesting development from SDRplay and mirrors some of the trends with other manufacturers of HF transceivers catering for remote operation.

In the case of the new SDRplay nRSP-ST receiver, all someone would need to do is to provide power, a network connection and antennas at the remote location. The concept of remote receivers isn't new but in most cases, a remote computer/PC is required as well as a receiver. In the case of the new SDRplay model, no remote PC is required.

The new SDRplay nRSP-ST would seem to have the same radio features as the RSPdx-R2 model except that it can be connected to a network for remote control.

One particular nice feature is that it has three antenna ports which allows for dedicated antennas to be connected at the remote end. Without this, it would be a case of having just one antenna port to cover all the radio bands below 2 GHz.

It's not hard to imagine how this remote receiver might be of interest to some people. Many live in towns and cities in noisy RF environments and the thought of having a remote receiver located somewhere quiet in say a holiday home or a friends or relatives house is attractive.

This would seem to be an all in one box solution for a problem and I'd imagine people will find all kinds of uses for it.

At about €500, it's not cheap for a receiver but it's also a new release with first adopters likely to be paying the premium price.

Addendum...

SDRPlay release new receiver - RSP1B

The UK based company SDRplay have just announced the launch of a new Software Defined Radio receiver product – the RSP1B.

The RSP1B is an enhanced version of the popular RSP1A 14-bit SDR which covers the RF spectrum from 1kHz to 2GHz. The RSP1B comes in a rugged black painted steel case and claims to have significantly improved noise performance.

The RSP1B has the following additional benefits compared to the lowest cost device, the RSP1A:

1. It is housed in a strong black painted steel case.

2. It has significantly improved noise performance below 1MHz (i.e. for MF, LF and below), and in the 50-60 MHz region. There are also noticeable noise improvements in the 3.5-5.5MHz and 250-320MHz spectrum.

3. It has improved signal handling at HF frequencies.

Some consumers don't like the fact that the older RSP1A has a plastic case coated in a conductive coating to screen it and many prefer a more solid steel case. The RSP1B addresses that issue.

I found it interesting that the performance at 50-60 MHz has also improved.

The RSP1B is expected to retail at approximately £106 GBP in the UK or $133 USD (excluding taxes or shipping) for US orders. 

Thanks to Brexit, the company can no longer ship to individual consumers in the European Union and has to go through the more expensive resellers network. This brings the price in the EU up to about €153 while the older RSP1A retails for about €133.

I suspect most people will opt for the slightly more expensive RSP1B but the price is now significantly more expensive that other SDR models available in the EU.

Video: Mid-Ulster ARC lecture on SDRPlay receivers

 

In the past, traditional good quality superhet receivers have tended to be somewhat expensive as they required a fair amount of hardware in terms of mixers, amplifiers and filters. In the last decade, modern software defined radios have turned this on its head and now, a good quality receiver can be bought for a very modest price.

In October 2020, the Mid-Ulster Amateur Radio Club had a lecture about the SDRPlay range of receivers. These are generally well regarded in terms of performance and price.

The video can be viewed below. It is somewhat long at 1hour 38mins. 

The main presentation starts at 02:29 and runs until 49:30. After that, there is a Q&A session which lasts for another 50 minutes.

SDRplay announce release of new SDR receiver

On the 1st of November 2019, SDRplay announced the release of their new RSPdx model. This is a software defined radio intended for reception only and replaces their RSP2 and RSP2 PRO models.

It is described as follows..."The SDRplay RSPdx is a complete redesign of the popular RSP2 and RSP2pro multi-antenna receiver. It’s a wideband fullfeatured 14-bit SDR which covers the entire RF spectrum from 1kHz to 2GHz. Combined with the power of readily available SDR receiver software (including ‘SDRuno’ supplied by SDRplay) you can monitor up to 10MHz spectrum at a time.
The RSPdx provides three software selectable antenna inputs, and an external clock input. All it needs is a computer and an antenna to provide excellent communications receiver functionality."

This particular model retails for about €200 / $200 which is twice the price of the RSP1a version.

SDRPlay seem to have a reputation for good SDR receivers at reasonable prices. The RSP1a looks like good value but I guess it depends on what you are looking for. The RSPdx has a metal enclosure with more sockets which might appeal to some.
