I agree. Looks like crap. I had a heck of a time finding archives a few days ago. It was not hard to find out who the commissioner was with the huge p...
Not entirely necessary but I would recommend keeping instrument and rod heights even if I am not really interested in elevations.
This will be interesting to watch. I have no idea who is right. I can believe either side at this moment.
Mighty Moe makes a great point. One thing I've found with sub-meter receivers in the past is that the errors typically stay consistent for hours. If y...

I'd be surprised if anyone is getting 5hz transmit over uhf. The only hard stance I've seen being made on this issue is that >1hz transmit improves...
I should clarify No. 4. Actually it isn't a least squares of the angular residuals (in angular units), it is a least squares solution of the arc dista...
