Optooelectronics used to make a box exactly like this, with serial port for PC logging and all that. I have one and and I'm *very* happy with it. (I'm sorry, but I'm not selling mine!) Checking the website they now have a box that includes a counter, too, but no longer the single decoder. Perhaps you can fleabay one of the older boxes? 73, Geert Jan
