HA! Just when I was getting ready to drop myself from this list, along comes a ham radio question! Shoving digital voice down a 100 Hz pipe would be mighty darned tough/impossible. N0YMV has a good suggestion. Try those WSJT modes. They use narrow bandwidth and are fun to play with. There are documented instances where moon-bounce QSOs have been completed with these modes. No, it's not voice, but it does work. Oh, JT65 mode in WSJT is designed specifically for EME comm...

Dear Sir, Could you please forward this e-mail to your engineering department. I am a ham radio person who wants to transmit from the Earth to the moon and back to the Earth by phone not by Morris code. This will be a very weak signal. I need an extra 13.8 dB of gain. Could you please help me distribute the attached paper to someone who could take this project into the next level? Please reply

...o it can be used in open standard software for amateur radio--as well as whatever else people feel like using it in. Our code will make its way back into the main tree. Jean-Marc, all of your hard work in reducing memory footprint and CPU usage is wonderful. Thank you, very much. Cheers, David n0ymv

...#39;s WSJT suite of modes? They were designed by Joe Taylor--who is an EME'er and very competent ham. They are all keyboard-to-keyboard modes, so you can cut out the whole voice side of things. No point in involving analog modes when you can keep it all digital. Best of luck. Cheers, David n0ymv

I was browsing through Microchips' website and came upon their Speex library. They are charging for it and looks like it is also not open source. http://www.embeddedstar.com/press/content/2005/6/embedded18391.html scroll down to the paragraph about pricing. - farhan
