Open TPUK on phone in browser, scroll down to find the QR code, click on it (or just scan it I guess!), you'll likely get a warning that it's not in Playstore. I had to reload it onto my S7 recently, after it refused to sync.

As has been noted, it doesn't work properly on later versions.

Indeed, almost 1km from the nearest trig on TPUK, although seems a logical place for one, if at the summit. I recall a Pathfinder map (not as old as 1948) in Mid Wales which had a lot of trig symbols in a few km2 of moorland. It made no sense that they would all be trig stations; needless to say we ...

What's the grid ref? If not already on TPUK it could be an "old trig" or a "ghost trig" i.e. non pillar trig, but if the latter it should already be on TPUK. What if anything has been found on the ground?

Red Hill is another http://trigpointing.uk/trig/5610

... and the other detail to http://trigpointing.uk/wiki/Passive_station Could do with formatting etc.

Still needs an explanation of how Passives are/were used though...

I've added some of this good stuff to http://trigpointing.uk/wiki/Berntsen#Berntsen Feel free to improve...

It might be interesting to add this info to the Passive Stations wiki page http://trigpointing.uk/wiki/Passive_station

However at present there's nothing there at all - anyone able to make a start? I've never been at all clear on how passives were used, and whether they still are ...

Turning the question around, are there any instances of Passives with Surface Block and Berntsen close together with each having its own station ref?

An example of an FBM with SB and Berntsen close together is the Oswestry FBM Aux 1 Berntsen H2SJ2724 http://trigpointing.uk/trig/606 which is close ...

Moor Fields http://trigpointing.uk/trig/7325 in West Yorkshire
is another instance of an OS Surface Block with a Berntsen just a few metres away; the latter is non-OS as far as we know.

Thanks Ted - that was the one I was thinking of, near Leeds, not Central Scotland :oops:

From others' Moor ...

Not me. Think it makes sense to merge it with the main Ballards Ash page. NB Ballards Ash seems to have two Berntsens equidistant from the SB.

Another Passive with an associated Berntsen is Failand http://trigpointing.uk/trig/287 - in that case included on a single trig page. Bailbrook http ...
