FreeDV 2.02 - crashes/exits when starting RADE

[Christophe David (ON6ZQ / AC6ZQ)]

After uninstalling FreeDV 2.0.1 and installing 2.0.2 on Windows 10, the program exits each time RADE is "started".  The other modes seem to work fine.

Rebooting, uninstalling and reinstalling did not help.

After reinstalling 2.0.1, same problem despite it used to work fine before upgrading to 2.0.2.

Any clues please ?

[Bob Sanborn]

I had same exact issue..........solved by upgrading to win11

Hi Christophe,

You may need to rerun the Python install script as Administrator to make sure the stuff needed for RADE is properly installed. This script is in C:\Program Files\FreeDV 2.0.2\bin\rade-setup.bat. Let me know if this doesn't work and we can investigate further.

Thanks,

Hmm, that should definitely not be happening for sure.

 

We have plenty of people using this on Win10 with no issues.

 

I have seen a similar anomaly when the audio sources were pointing to something other than what it should be.

 

You might try bringing up the software, (do not start the modem yet) Go through the audio selection choices, and reselect them, even if they are correct.

 

See if that has any effect on things, and let us know.

 

Many thanks,

Walter/K5WH

Thank you for your support.

  1) I ran C:\Program Files\FreeDV 2.0.2\bin\rade-setup.bat as administrator.  No error shown.

  2) I changed the audio selection choices, and reselected.

The issue is still there.

The other modes seem to work just fine, waterfall OK, etc.

I recorded the screen : you can see I switched all modes analog/digital, then finally RADE when the program exits.

See https://on6zq.be/video/fg.php#pid=FreeDV_2_0_2.mp4

As I do this remotely using AnyDesk, I also disconnected the remote session and asked my friend to try "locally".   The issue remained the same.

My own setup works fine, and I could not spot the difference with his so far.

I thought all of the other modes except for RADEV1 were disabled now
since they won't be used with the better audio of RADE?

We still have some of the legacy modes available, they are useful for
demonstration and comparison.

RADEV1 is only available when specifically selected, if one of the
legacy modes is selected you can use any of these in the multi-rx mode
but RADEV1 cannot be available due to the compromises in the current
code structure due to the python libraries in use.

Eventually this will go away but the exact mode support that will be
provided is still under consideration.

Hi Christophe,

Do you happen to have Python already installed on your system? i.e. for use by an app other than FreeDV? I wonder if that could be interfering with FreeDV somehow.

Thanks,

>> Python already installed on your system

I am helping a friend.

I ran FreeDV 2.0.1 and upgraded it to 2.0.2 on my personal system without any issues.

The issues are on a friend's PC, and I help him remotely.  Hence my doubts about side effects of the remote control software, but the symptoms remain the same "locally".

As far as I can see, there is no other Python installation on the PC.

I tried to get info using the "console" mode, but the program exists when starting RADE and closes the console too.

Is there a command I can execute from the FreeDV /bin directory that would launch Python the same way as the FreeDV GUI, in order to try to get some usable error messages displayed ?

[Mooneer Salem]

If Python is working properly, I would expect something like the following when run from a Command Prompt window:

C:\Program Files\FreeDV 2.0.2\bin>.\python
Python 3.12.7 (tags/v3.12.7:0b05ead, Oct  1 2024, 03:06:41) [MSC v.1941 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import radae_rxe
>>>

If you get an error message after entering that import command, please provide what it says so we can investigate further.

Hi Christophe,

This sounds like the Visual C++ Redistributable didn't properly get installed. It should have as part of the FreeDV installation process (if not already on the system) but you can manually download and install from https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170. Let me know if that fixes RADE for your friend.

Thanks,
