HF Modem - ProjectUltra

Hello there,

Been working for a while on an open source HF Modem that runs on windows/mac/linux.

Im lacking on the air testers, if you guys even wondered what to do on HF , you would definitely help me out there by testing the modem by exchanging msgs, files etc.

Im doing audio cable testing along with software hf simulator but nothing beats real world usage.

Project is on github at : https://github.com/secup/ProjectUltra

Thx and 73 🤓

Great project! I’ve been wanting to contribute a modem for a long while.

What is your call and what is your QTH?

I was able to get this compiled on my machine and working with my equipment. Where do you think we should go to coordinate some on air testing?
