What would be slick would be if you could program a bar code reader with a
prefix and/or suffix..... I'm sure could be done with an additional pic
chip.  so you scan a bar code that represents a callsign and the reader
appends the position and sends.  would be good for applications like
scanning runners past a checkpoint.

In theory there is no difference between practice and theory.
