Digital speech within 100 Hz bandwidth
...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 communication. I used the HSCW (high speed CW) for meteor scatter & had a lot of fun with it. Best of luck in your EME endeavor. Oh, what is your call??...

Digital speech within 100 Hz bandwidth
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
