Hi Chris,

Thanks for the feedback.  Do you happen to know the parameters you have setup for yours?  Just wondering what you are using for the "F", "M", and "S" parameters.  What kind of receiver are you driving yours with, and do you have it in "position hold" mode?


Bob

(does happy dance)  Now that it's had some time to warm up I see that it's started wandering around +/- a couple of counts from sample to sample (16 seconds).  Is this because the UT+ is not set to timing mode?  Putting in an RS-232 (or USB) to TTL adapter, switchable between the UT+ and the VE2ZAZ board, is pretty much next on my schedule.  I've got an adapter I made many years ago, but it's not suitable for mounting in the box, and there's no simple way to hook it up to the UT+ at the moment.
