well got my head/hud back from jurgensen and have made some dives with it they were unable to duplicate the problem because it was operator error. i had been inadvertently been going to "set stack time " instead of "reset stack time" on the secondary handset. as soon as you execute this function, the led will freeze in whatever spot it is in. in other words if the the led is on, it freezes on, if it is off, it stays off. we tried this on at least four other optima hammerheads and they all did it. my bad.

so, the hud is working fine now that yours truly has corrected the error of his ways. kudos to jurgensen for the quick turn around
