I guess I am naive, I thought no one would want one and it would be cheaper than that. I noticed there is an ARK2 on ebay for 350GBP ($580). I paid WA...

My T3 has nothing like that, but I am pretty sure that is to help aim at stars. In my old age I find it more difficult to aim the scope at a particula...

Scott: glad to hear that SOMEBODY still calibrates regularly, besides me.Our last calibration was at a new CBL in Ohio (CULVER DAVIES) that uses pilla...

I have quite a few, but none in Texas. Most of the NE and also MN-IA area. I really wish someone would make these into DRG's or at least PDF's so that...

That is one reason, Chris. But, running forward-back can also help minimize or detect any error due to settling of the instrument. Since we are in an ...

Chris: thanks for that, now it is much clearer on what it is. To answer your question, no, we only use one rod. Not that two wouldn't be better, but t...

Thanks, Scott. Looks like something that would be easy to make. It would be easy to carry a couple of pieces of 2X4 in the truck and cut them to fit w...

Mike: you are absolutely correct in that the crosshairs of a digital level are NOT what the level uses as the horizontal axis for observations. The cr...

Christ: not sure what you really need, but as far as I know there is no R8 data in this file. But, I did create a .jxl file out of it. .jxl fileNote: ...

Mike: I figured there must be such an item, but it is not shown in the manual NOS NGS 3, which is where I would have thought it might be. I will ask t...

Thanks, Chris. That sounds like a good design. If you could, I would appreciate a picture of your "device".

This is for second order class I levels, doing a "measure down" isn't going to help at all. We use 3 m invar rods for the leveling, and a 0.5 m invar ...

I have an Intuicom RTK bridge. The way we use it is that it looks just like a standard RTK base radio transmitting corrections from a nearby point. Th...

I don't know about .t01, but it will work with .dat files (use runpkr00). That said I prefer to send rinex.

I hope to go, Richard. But I have not looked into it yet. I will check it out in the next few weeks and let you know.

well, they are on the upside down part of the earth (down under)

Unfortunately, that does not show how it really is. In the past, on other boards, I have used for to preserve formatting, but on this board that does...
