Assorted ramblings from the developer

Release: 3.0.4

Download here [Link].

What's new / changed in 3.0.4:


  • ADALM-PLUTO transmit and receive support added.

  • Airspy HF+ support library upgraded to latest release, CPU usage now much lower.

  • Airspy HF+ supports pre-production units properly, also units with old / original firmware.

  • ANAN code given a lot of attention, working much better.

  • bladeRF2 now checks that the frequency is within the supported range.

  • Lime transmit support added.



  • Added Pseudo Stereo (ribbon bar, Receive, Mode..., Pseudo Stereo).

  • Downconverter supports frequencies up to 999.9 GHz.

  • Frequency database supports a Custom CSV layout.

  • Frequency display supports frequencies up to 999.9 GHz.

  • If there are no receivers a warning is displayed.

  • Signal History - added Slower and Very slow.


  • Audio buffering logic updated (the way I maintain the buffer between demodulation and the playback / VAC device). This is simpler, cleaner and gives me a good base for the future. See the Playback Buffering page for options.

  • Audio recording – a check is made that the folder exists before the recording is started.

  • Fixed spectrum display in Auto mode when input signal is very low / zero.

  • Fixed crash adjusting the Span (bottom of display).

  • Fixed crash caused by a change in output device options such as enabling spatial sound.

  • Fixed obscure bug in the Select Radio user interface.

  • Fixed SAM demodulation, PLL was not working fast enough.

  • More visibility/sanity checks when restoring a window position (example: Select Radio).

  • Obscure fatal bug saving/recalling complex Favourite definitions fixed.

  • Product name and date now always shown at the top of the main display with all display styles (long-standing MFC bug fixed).

  • More logic in coding where the program priority is raised when the system starts.

  • If the signal is muted due to input overload a warning icon is now shown in the status bar, previously just the Auto Mute text was shown. (This caught me out a couple of times).

Recording Scheduler

  • Interface redesigned, simplified with no loss of functionality.



  • Now displays correct TX mode in the main window's ribbon bar tooltips.

  • Now uses fixed point fonts for name and times.

  • Fixed fatal error selecting a world map which cannot be opened.

  • External Radio now supports both Rig 1 and Rig 2.

  • TLE data now has better sanity checking.


  • Reduced dangling connections on the server.

    If you want to take a break from DX on the ham bands, why not try Band II DX? Version 3.0.8 (coming soon) has an automatic log of received stations. More information is available here.
  • Release: 3.0.7 Posted 2 weeks ago
    Download here [Link]. What's new / changed in 3.0.7: Data Recording The WAV file format upgraded to WAV RF64 is only used if the file size if set to a value greater than 2GB or unlimited. File szes of 2GB or lower use the original WAV format and will be compatible (should be compatible) with other 3rd-praty programs. Es'Hail 2 Beacon Added Beacon synchronisation: . This is an option to using a TCXO or GPSDO and is used to compensate for LNBs which are not stable. LimeSDR Calibration All Lime-relation calibration options are now user-configurable. The option of changing the offset frequency has been added. Some brief tests on 2m show that offset tuning may not be needed. TX calibration should ideally be run when the drive level is changed, this affects the Lime internals, so maybe the option of running TX Calibration automatically when the drive level is changed should be added? Note: you cannot properly monitor your own signal using the same device that is transmitting. General Improved performance when scrolling the receivers – there was unnecessary processing when scrolling in a receiver window. Serial Port (CAT Control) WSJT ...
  • Free ADALM-PLUTO Posted 3 weeks ago
    Just saw a tweet from @robinlgetz - this is an excellent offer. 2019 Hands-on workshop using Software Defined Radio, across the US and Canada. Take home a #plutosdr , “Software Defined Radio for Engineers” text (pdf) and trial of MATLAB. For more information, check out : Enjoy!
  • Es'Hail 2 Beacon Posted last month
    There's a big problem with consumer LNBs - they drift, and drift badly! One way of correcting this drift is to monitor the telemetry beacon, determine the actual received frequecy of the beacon and hey presto - we have the offset! Quite a bit of coding involved, but when you decode BPSK you actually have the offset if you pay attention to the code. Add a nice waterfall so the user can select the beacon, add a bit of funk and we're more than half-way there. Here I'm plotting drift versus time.  Also it's nice to see Es'Hail 2 being used more as people get their systems together. Code will be in 3.0.7 - within a week I hope.  
  • Release: 3.0.6 Posted last month
    Download here [Link]. Note: 3.0.6 fixes / enhances the support for Lime and PlutoSDR. What's new / changed in 3.0.6: Data Recording The WAV file format upgraded to WAV RF64 which supports an unlimited filesize, previously the maximum filesize was 2GB. No more XML files being created. Analyser updated and tested, seems to be OK with these big single-file recordings. Tested with 3rd-party recordings: Perseus, ELAD S2. Redesigned the Playback Select window (below). If you have a lot of recordings this is should be better to use. When you make a new recording the individual filesize is now optional, if not enabled then a single file is created. General Fixed a bug which had been in the code since day 1 (about 4 years ago). As this was thread-related the crash happened rarely, depended on CPU speed and other factors. Restarting a radio/recording could cause a crash due to bad thread synchronisation: Changing radio bandwidth, Starting recording after the radio was running, Starting radio after playing the radio. Default stack size now 2MB (was 1MB) Added a Mute option ...
