Raspberry Pi as a Ham Radio WSPR transmitter

I know this isn’t new news. but given the work I’ve been doing recently with the Raspberry Pi and since I recently got my ‘General’ Amateur Radio license, the fact that you can use the Raspberry Pi as a low power transmitter for the Weak Signal Propagation Reporter (WSPR) network I find fascinating. Definitely have to get myself setup to investigate some of these digital modes.
