Steve Andrew’s spectrum analyzer software for SDRplay SDRs now available for download

A few weeks ago, we posted an announcement that spectrum analyzer software was being developed for the SDRplay RSP software defined radio series. Many thanks to Andy, at SDRplay, who shares the following announcement:

We are pleased to announce the availability of the first cut of Spectrum Analyser software developed by Steve Andrew specifically for the RSP line of products. Please note that this is first alpha software and so it is still very much in development and some features are still to be added. Currently supported are:

  • RSP1
  • RSP2/RSP2pro
  • RSP1A

This first alpha release gives a good idea as to the look and feel for the software. The main functional limitation is that sweeps of greater than 10 MHz are not currently supported. Steve is currently re-working the algorithms for providing wider sweeps than 10 MHz to improve sweep time and remove the issue of the DC spike in ZIF mode, so please bear with him.

We recommend using the software with AGC turned off and use manual control of the gain for better display stability.

Ivan performs two tests with the AirSpy HF+

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who shares the following:

Thomas, there has been a lot of discussions regarding Airspy HF+ ever since it came out – heated exchanges regarding comparisons with peers, modifications and firmware updates.

I took my Airspy HF+ and conducted two tests with it:

Airspy HF+ vs. SDRPlay RSP-1A on HF and Medium Wave

Since I could not completely equalize the audio levels, I think it’s good to look at the peak to valley ratios on the display rather than the audio volume.

This comparison used SDR #. It may be helpful to run the same comparison on SDR Console V3. I may do that at a later time.

Both tests used W6LVP’s portable amplified receiving loop antenna in a noisy suburban backyard in Florida.

Many thanks, Ivan, for sharing these comparison tests! I agree with you that it’s most helpful to look closely at the peak to valley ratios on the spectrum display rather than using the audio levels as a measure.
