I’m beta testing a RTTY Bulletin Board System on 28.090 USB in which I’ve developed. It’s functionality is currently limited but you should be able to connect, get a local WX report, get a rudimentary signal report, and see the last five connections.
Other functionality will be developed soon and as soon as I can work out the bugs I’m hoping to share this with others who would also like to set up a BBS using RTTY.
For those interested, the software is written almost entirely using BASH and utilizes a really cool piece of software minimodem (http://www.whence.com/minimodem/) for the FSK translation via sound card.
Anyway, suggestions are greatly appreciated. Feel free to connect and try it out.
