Hi folks! I've found Terri Cherr's idea of using VHF data modules excellent, not only to exchange voice, but to communicate to a host computer also.

That will only allow one half of the conversation. I suppose you could run with two kits, one receive, one transmit, both tuned to different frequencies. Another suggestion might be one of the cordless, battery operated intercom system units. Most (...) (27 years ago, 4-Dec-98, to lugnet.robotics.handyboard)

That's a hard one because you have to have sufficient gain from the robot microphone to hear someone 2 to 8 foot from the microphone. Usually communication equipment limits their microphone gain on purpose to exclude background noise. You have to (...) (27 years ago, 4-Dec-98, to lugnet.robotics.handyboard)
