====== Line Transmit ======

A slightly more compact version of the MBHP Line Driver Transmitter.

===== Schematic =====

[[http://www.ucapps.de/mbhp/mbhp_line_driver_transmitter.pdf|MBHP Transmitter]]. 

The two obvious differences are the J3 jumper (disconnects +5V from being sent) and the addition of a 100mil header. This way a DB-25 (or something else?) with ribbon cable mounting could be positioned off-board and wired to the line driver with an IDC.
