Wondered if anyone had a rtk up grade module for sale?

I might have one for sale if I just could reach a local sales person to purchase a Novatel kit. Now approached the country sales manager after contacting a few sales people, still no response what so ever.

Some have been on sale at AGCO trader. At least one was on sale at agriaffaires.co.uk. Several complete receivers too, one complete receiver was less expensive than the sales item including only the gyro and RTK modem.

Are you going to use the radio or just NTRIP? Note that RTK parts should be compatible from Fendt and original Topcon receivers even if the actual receivers have different SW. Radio frequencies vary, need to check that if purchasing from a different country.

New to this GPS thing but I think I just need NTRIP .if that's the one that work of phone masts.

NTRIP is the one that uses cellular connectivity for RTK correction data transfer.

One more issue to be considered. The older AGI-4 modems were 2G (GSM/GPRS) only. Later models were dual mode GSM/UMTS. At my place it is UMTS that has almost been refarmed with 4G/LTE while we still have perfect 2G coverage (for the low cost internet of things etc.). In the UK the situation is likely different. You might end up needing an additional external modem. There is a connector on the receiver for an external modem but it adds cost unless you are handy and build a bluetooth serial converter and feed RTK correction data from an ordinary (4G) phone. You would still need the OEM modem to "unlock" RTK on the receiver.

Does anyone know if fendt and Massey rtk parts are interchangeable both being topcon based.

No, the main receiver part is not interchangeable. The SW inside is different. Fendt has its own variant, MF/Valtra/Challenger use the same and that too is different from the Topcon branded box.

The add-on parts should be interchangeable, the gyro unit and the RTK modem.
