What's new / changed in 3.0.8:

Broadcast FM

New features and changes for 88 - 108MHz FM broadcast reception and the RDS decoder.

RDS decoding has been improved by making PI code detection mor sensitive.

US Callsign logic now uses data from NRSC for callsign and location.

Spectrum window now a docking pane. Display the spectrum window by selecting Ribbon Bar, Receive, Broadcast FM. 

Logging of station from the RDS decoding has been added, this is the RDS Logfile option. To display the logfile click the Log button in the BFM Spectrum.

The logfile has all the options you need:

  • Enable / Disaply updates
  • The number of recent entries displayed
  • Detail level (brief, full)
  • Font size for ageing eyes
  • Delete entries
  • Edit an entry
  • Export as text
  • Options

Click ••• to display the options.

Airspy Options

The Airspy options have moved from the ribbon bar to the Receive DSP panel.

USB Relay

The USB relay terminology has been changed to avoid confusion.

  • ON = Turn ON a relay channel (Activate).
  • OFF = Turn OFF a relay channel (Deactivate).

Data (IQ) Recording

Playback now correctly detects ELAD recerdings and displays the format as ELAD. later the contents of the elad chunk in the WAV file will be supported.

Scheduled Recordings

  • Now can select single file in the definition, this uses WAV RF64.
  • Fixed display issues.
  • Tidied up the code.

Geostationary Beacon

  • Increased bandwidth for LNBs with very serious drift!
  • Fixed crash when bandwidth changed past the minimum / maximum supported.

Frequency Database

AOKI URL updated and new format supported.

Font size selection for ageing eyes.

Defauly field order changed, will be user-configurable in a future release.


The sample rates 192kHz, 96kHz and 95khz are now calibrated.


Tidying up and extending the Select Satellite option. Instead of just selecting a satellite, pressing Select in the Satellite ribbon bar now display the Select Satellite window which provides an overview of the entries in the Satellite List as well as selection of new satellites.

Footprint configuration is now consolidated into a property page.

Narrow FM

Uses the original version 3 de-emphasis and has better peak volume control.


Problems with the transmit signal bursting reduced by redesigned inefficient code, see Pluto support page for more information.

  • DRM in SDR Console Posted 3 days ago
    I'm often asked to incorporate a Digital Radio Mondiale (DRM) receiver into SDR Console. The reasons why I haven't done this are: Patent / royalty issues with the audio codec, and The Dream project works well. Brendan Wahl, WA7HL, co-Moderator, of the DRM North America Newsgroup explained the lagal minefiled recently. The text below is reproduced with his permission. Hi all, got some background here for you. I've been following DRM since the beginning,  and still admire it for its broadcast quality and capabilities. The DRM system was originally written by the Frauenhofer Institute in Germany, with the first software for personal use requiring a license key that cost the individual listener somewhere around ~€49/$49. I've got one somewhere, but I haven't had to use it since the freeware "DReaM" came out. No key needed when using that software package, which is still available on Github IIRC. The original commercial software still works, but it's very simple and doesn't provide a lot of bells and whistles. I'm not sure it's available anymore. What happened was that the AAC codec (and it's variants, esp. XE-AAC...) was ...
  • Spectrum Markers Posted last week
    Now that I'm spending more time on 2m (144.5 MHz) I decided to add spectrum markers as it makes beacon identiciation easier. Here's a 2m screenshot taken today, as you can see there's not a lot happening. A simple window for adding definitions: And another for the appearance: When time permits I'll add support for adding data from a CSV file.
  • WiNRADiO Sigma (G65DDC) Posted last week
    Nils Schiffhauer dk8ok has helped me a lot in the past, so when he asked me to support the WiNRADiO Sigma aka G65DDC how could I refuse? This is a beast of a radio, I've not encountered anything like it before. There's one problem - I don't have one, so testing could have been a nightmare. However, the API is very clear and well documented. After just two days exchanging code with Nils he has now reported that the Sigma is working, and working well with the features in SDR Console that he needs. This is the first time I've added support without ever seeing the hardware, so kudos to the team at WiNRADiO. The SDK's API is here: . I'm so impressed, I may add support for more WiNRADiO radios if there's demand. Here's an example of the Sigma running with a 33.3MHz sample rate and we see the whole of HF! Support will be in version 3.0.11 of SDR Console which at the time of writing has not been released.
  • Release: 3.0.10 Posted last month
    Download here [Link]. What's new / changed in 3.0.10: General Audio device dropdown now shows a check mark next to the current device and L/R channel selection. SDRplay radios – sanity check that the default frequency is valid – must be in the range 10 kHz to 2 GHz. previously a user started with the default frequency of 10Ghz which is not supported by the SDRplay library. FM Stereo RDS logging was not working properly with multiple active receivers. Fixed a long-standing bug in the tuning bar at the bottom of the main waterfall; this was an error which existed since the code was originally written over four years ago. A determined fool-hardy user could expose the problem and crash the program. Scrolling at 8.333 kHz with rapid middle wheel spinning works properly. Identity title now optionally shown in the program title bar. DSP More taps available for filters. Corrected DSB filter editor. Narrow FM de-emphasis redesigned to avoid audio pumping. NR3 reworked. Threshold changed to Level, working much better. Filters: Changed appearance of the Filter design window. ...

    A very nice opening this morning to Morocco on Band II Stereo (88 - 108MHz).
