No, bit banging.  Using the UART and line driver to communicate with a PC or
PalmPilot.

I thought I had read that an unbalanced stream could cause the receiver errors
with these types of receivers.

Not sure I follow, what's a one-meter-band encoding scheme?  I'm transmitting
very simple packets no more than once every five minutes.  The packets contains
on/off and transmitter id type data.  Again this is just for hobby use, so I
thought I was FCC part 15 cool.

Thanks again,
