 I want to give a follow-up to the problem that I was having with the
 stormscope giving wrong indications of heading to the Chelton system.
 As suggested by Kirk, it turns out that the problem was two missing jumpers
 in the wiring at the Stormscope interface.  These jumpers allow the Chelton
 system to supply heading information to the stormscope.  With the jumpers
 installed I now am getting the correct display on the stormscope utility
 program.  I've yet to verify results with real conditions but I'm confident
 that the display will be correctly oriented.
 
 Thanks to Kirk and Steve (at Chelton).
