What WAV-format does Rogue Master's WAV player expect?
Yes indeed, I'm using Rogue Master 0.63.2-0728-RM-T. In a gist, I'm creating files containing monotone sound signals created by ggwave. However, by default ggwave writes 16-bit WAV files, and playing these is neither supported (it's mentioned in the code) and results in pretty garbled output. But I get output.

Replacement PCB Replicates Early 80s Modem
This will get you started:
Tony Fisher wrote V.32 soft modem stack for SGI Indy back in 1996. York University couldnt handle hosting whole 8 megabytes of his stuff https://www.cs.york.ac.uk/news/fisher/home-page but at least they had the decency to upload it to github instead of just deleting https://github.com/university-of-york/cs-www-users-fisher/tr... Randy Rossi rewrote this project and got working V.21/23 https://github.com/randyrossi/fisher-modem
Fabrice Bellard, because of course he did :), implemented his own version all the way to V.34 with parts of V.90 https://bellard.org/linmodem/
V.21 modem implemented in Gnu Radio https://web.archive.org/web/20170627151353/http://aaronscher...

Is there a standard for transmitting unencrypted plain text data? (Strings)
This one is excellent, you can transmit and receive data as audio OFDM : https://github.com/romanz/amodem You will probably need to pipe it to a modulator for RF transmission.

Internet/TCP socket data over SDR?
https://github.com/romanz/amodem is the tool i used to wrap netcat data into.
