Solved.
Thanks to Ryan and Marcus for their help.
/Note: Some of these paths might be different depending on exactly how
you installed Radioconda, this is how it installed on my system./
Open a command window at,
|C:\Users\steve\radioconda\Scripts|
(Or where ever you find a ‘conda.exe’ in your install)
now run the command,
|conda info –envs|
This will tell you what environments are available, in my case it
reports ‘base’
In same command window, type,
|conda activate base|
Now to find the prefsdir file locations type,
|gnuradio-config-info –prefsdir|
In my case this reports,
|C:\Users\steve\radioconda\Library\etc\gnuradio\conf.d|
To find the userprefsdir type,
|gnuradio-config-info –userprefsdir|
In my case this reports,
|C:\SPB_Data\.gnuradio|
These are the directories where conf.d and config.conf are located (at
least on my system).
