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.
- Show HN: I made a tool to communicate data using the PC speaker

solar + LTE tide sensor
I want to lead off with a big shout-out to Botletics and their (his?) SIM7000 LTE CAT-M1 shield. From the beginning I knew I was going to need wireless connectivity and that WiFi was not going to reach. I considered Blues Wireless, but ultimately went with Botletics + hologram.io and I'm extremely glad I did. I plugged it in, I lightly modified the example code (it was pretty close to what I needed already, I basically just took out the GPS reading and replaced it with an averaged HC-SR04 ultrasonic sensor reading) and it just worked.

Ask HN: Is anyone working on a open hardware 3G/4G dongle?
Depends how open you mean. For a lot of hobbyists and integrators, this works:
https://github.com/hologram-io/nova-hardware
And run this on a Pi:
https://github.com/hologram-io/hologram-python
If you need something one layer deeper on the module or chipset level, there’s not really a lot out there.
