Earlier this month, I listened to a 2012 spectrum recording of the 31 meter band–RCI’s north Quebec service was transmitting on 9,625 kHz. I sure do miss them on the shortwaves but I’m glad I can do a little radio time travel with my SDRs and tune in once again from time to time.
Perhaps you could upload the I/Q recording (I know it will be big!) to archive.org for others to enjoy Thomas?

I would love to, Stephen. I don’t think Archive.org would allow files that large, though. This particular recording was maybe 640 kHz wide divided into 2 GB chunks (roughly 4 minutes long). Prior to the service closing, though, I did make some narrowband (24 kHz) I/Q recordings centered on 9625 kHz that contain perhaps more than 1 hour per 2 GB chunk.
One issue though is that my upload speed is .15 mbps and not terribly reliable. The compromise I have living in such a rural area.
I may be able to upload some files to Dropbox and share.
My dream is to have a site like the Shortwave Archive where people can share I/Q files. Sadly, most sites don’t like the idea of serving up files that size.

This file sharing site advertises itself as being “A Better way to Share Large Files”.

Their file size limit is 18 GB.
I found the website just yesterday.
This brings up a fascinating feature of SDR radios that I have yet to play with – recording a swath of frequencies for later ‘listening’. I could, for example, capture the 31 meter SW band and at a later point in time replay the band and tune various stations out of that captured bandwidth.
