- wyldfire 8y agoAwesome! A GMSK modem in js? Good on you. Submit for show HN? Have you tried other modulations?
- brian-armstrong 8y agoThanks! It made the rounds on show HN a couple years ago. Also my dirty secret is that it isn't really JS, it's C via emscripten https://github.com/quiet/quiet https://github.com/quiet/quiet Currently supports everything Liquid DSP supports which is GMSK, PSK, QAM, OFDM and a lot more. Working on adding DSSS soon edit: Here's a sort of lab/playground https://quiet.github.io/quiet-profile-lab https://quiet.github.io/quiet-profile-lab
- Sammi 8y agoSo what transmission rate can you hope to get with this?
- brian-armstrong 8y agoDepends quite a bit on what you have. I've seen about 10 kbps over air and 64 kbps over cable
- AstralStorm 8y agoIt is pretty conspicuous over the air though. It also won't get rid of watermarks. TEMPEST is probably easier and more reliable than this.
