Hi,
reading this - have you been able to get good positions from time to time - or have you never seen anything below 10 inches.
A decimeter subscription gives you 10cm in good conditions - so roughly 4 inches.
If you don't get down to this I've a flood of questions:
1. Are you using Trimble Correction Hub as source or a custom NTRIP stream
2. If you connect in TMM and wait say a minute - what type of correction source to you see?
3. Where are you located/ doing the job (you can also send this info via mail).
So with a decimeter subscription you would typically receive NTRIP RTK corrections - assuming you are in a region with VRSNow coverage (or any of our partners). Otherwise RTX IP would kick in - here it needs some minutes to converge down to 4 inches - but it should reach that state after some time. If you have no internet either it falls back to RTX SV - which takes a bit longer then RTX IP (because of less data via the satellite beam).
A good overview on both RTK and RTX availability can be found here: https://positioningservices.trimble.com/resources/coverage-maps/
It would also be good if you can send us a log via TMM. So if you connect in TMM to Catalyst, collect data for say 2 minutes, disconnect etc you can click on 'Information' and 'send email' and the email will contain a zip attachment with some details on your position/ received connections/ problems etc.
