Maybe build something with a PIC or something .. :wink:

Thanks for your help ....

Well the cutting edge of some of the communications research is being done in MIMO technology. The use of multiple antenna arrays to transmit information. The new 802.11 standard called N, will be out shortly and that is going to use MIMO technology.
