Re: FDM-SW2 Update

Bill Nollman

Otso, you are correct. I have found that the screen “drifts” over time. It’s probably a Windows issue but sometimes I do need to adjust the position of SW2 so that the original mouse-auto-click settings work. But it is so much easier to press F-keys than constantly clicking with a mouse. If anyone needs help setting it up just ask.


You do bring up a good point and something that I wish ELAD might be able to help with. I too will often A-B loop a top-of-hour or short section of a playback file and then want to review every frequency. For a 24MHz FM capture the loop feature is a huge help. But if the loop starts at the end of file_000.wav and ends during file_001.wav the A-B loop doesn’t help and it’s very frustrating. What would be very useful is either a way to manually combine 2 wav files so that A-B could be used on the new combined file (the file change would be in the middle instead of at the end of file_000.wav) or if A-B could be made to loop across 2 files.

Thanks for the suggestion, Bill. I tried Mouse-Auto-Click a few years ago but I did not find it very convenient for some reason. It seems to have ”disappeared” from my computer now. I suppose one of the challenges with this approach really is the difficulty to ensure Windows stay exactly at their place.


I do not think it would be very difficult to make the in-built SW2 (minimum) jump length to be configurable.


My 24 MHz files are about 10 min and 1.5 MHz MW captures about 40 min. I do not like a huge number of separate IQ files and even if the file-to-file transition is very smooth in SW2, at least once I have been unlucky and lost an ID just at the transition point. Therefore, I want to minimize the number of file transitions.

I use free software called “Mouse Auto-Click” that will click anywhere on the SW2 GUI to skip ahead and back during playback.

I programmed F5 through F11 to skip ahead in 10 second steps (assuming 1 minute 24MHz S3 captures).

As long as you have SW2 in the same screen position every time it works really well.

Give it a try and if you’d like details on how to set it up let me know.

Hi Vianney,


I have done some testing already:

  • I really like the possibility to use keyboard commands during playback, i.e. even if I use the mouse to jump within the time scale.
  • The Ctrl-F & B are a nice addition, but as I like to use quite a long file size (over 30 min), 10% is often too much as a standard step. A possibility to set the percentage (in settings) would be a great thing.
  • I have missed a way to quickly jump between frequencies during live sessions. Therefore, I believe I learn to like to Ctrl-Z/Y shortcuts.
  • I was not able to figure out how to use the Station Memories window during file playback. I tried clicking with the mouse as well as several key presses on the rows. The only thing that changes is the mode, if defined with the memory entry. (This is how it has been earlier, too.)
  • It seems that I cannot enter notch frequencies or related bandwidths by typing them into the respective fields anymore. Otherwise, I suppose that their usage with the new shorcut Q might be bit quicker now. I hope this bug will be quickly mended as I use both of the filters almost all the time when listening to MW files (to block adjacent channel QRM). I would actually like to have a couple of additional  filters!
  • The equalizer har really never worked for me: It is disabled when I open the AF Window and the ”ON-button” is greyed out.
  • Jump to start/end may turn out useful, but Ctrl-Shift-F does not take you to the next file. It takes you near the end of the current file and in my case with long files, you have to wait a wile before playback takes you to the next file. I would really appreciate proper jumping between the file sequence. Back and forth!


Thank you for your continued work on this great piece of software!

BR, Otso



I  have lot of memory entries, mostly MW offsets as well as ”watchlist for AM and FM:

the version 3.53 of the SW2 software is available in the Under test folder along with some release notes.

The most important changes are:
    - possibility to change the background of the spectrum and to save on file all the colors that can be set by the software,
    - added the possibility to choose whether to display 9 or 12 digits for the Advanced Tuning window,
    - improved keyboard shortcuts management (with addition of new shortcuts),
    - added the possibility to use the memories even when playing a file,

    - improved software stability for the S3.
