Off the shelf underwater acoustic modems.

Ultimately I would like to source an off the shelf solution for underwater communication. Unfortunately the ones I have found are rather large and fairly expensive. If anyone has a solution I'd like to hear it. Making one might not be too difficult either: http://courses.cit.cornell.edu/ee476/FinalP...

Re: 315MHz RF, atmega32, wireless interference from a motor.

Excellent news! Thanks to all of your suggestions and help. I have easily doubled the transmission distance, this is the most progress I have made all week. Actually to is the only measurable progress I have made. I didn't have all of the parts in stock that you guys have recommend, but let me summa...

315MHz RF, atmega32, wireless interference from a motor.

I am currently controlling a water pump with an atmega32, a n-channel logic level mosfet and a WRL-08948 315Mhz receiver. The system works very well at close range, ~10 feet. But if I increase the distance between the transmitter(WRL-08945) and the receiver, the MCU does not receive all of the data ...
