I spent some time going down the rabbit hole of getting a Pi set up to continuously do WSPR monitoring using Rob Robinette's wonderful WSPRdaemon. His software has just had a major release and it's available on GIT. While it's focused on Kiwis (ANY kiwi, I suppose, not just a local one) it appears to allow audio input from other sources. Features include extremely flexible time and band scheduling, and a very simple configuration (WSPRnet setup, and various data extracts) file with in-line documentation. The software runs problem free and seems very stable.
I'll be running both QRSS and WSPR monitoring on 22M , and WSPR on 630 24/7 from now on. Reports will be sent to Wsprnet with K5MO-1 as my reporting call. Looks like there's pretty good coverage of most of the country now for 22M at least. The QRSS instance may be up and down over the next couple days as I migrate it to the Pi4 brick that's doing the WSPR decoding. The 22M QRSS grabber also makes use of a Kiwi (any kiwi) via KiwiRecorder and is Pi based.
It will be interesting to see how well these configurations do compared to reception on a "normal" receiver.
Not having to run a noisy, power hungry PC is a real plus though.
