What a beautiful little package, if only I could afford 1000 LOL. Oh, this reminds me...

There exists a simple Tx/Rx that I bough from some web company (will dig up the receipt)
which transmits 8 bits of digital data. I also purchased some Holtek chips for remote
control car operation (and, these chips connect with an H-Bridge, which I got from
Zetex). Anyways, the Tx/Rx are 5 and 7 pins, low V low A, cmos, and, I think are around
300-450 mhz.

Could be used for digital transfer? I don't know, I know 8 bits isn't much, and they are
one way, but they can be easily be interfaced with Holtek chips for remote control
applications, and you could get two of each.

Anyways, I just had to post so I wouldn't forget. More details tonight.
