Teejet auto section control playing up with trimble auto steer

[JCfarmer]

If using both together(don't use autosteer on the sprayer that often) the teejet section control can go all over the place and shift its line and field ends.
Both antennas are on the roof of the sp sprayer and about 6 inches apart.
Thoughts and experiences please.

Antennas shouldn’t interfere with each other, but try moving them further apart and see if that helps?

Both RTK, or two different signals? When one is rtk and the other is not that might be the problem?

Don't know what is happening there but why not only use the Trimble antenna and feed NMEA from the Trimble receiver to that teejet box (even when not using autosteer).

Both on egnos at the moment.

Both on egnos at the moment.

Could they each be using different EGNOS correction satellites? That could explain it

Is that easily doable, it's a 750 Cfx screen with auto pilot bought 2nd Hand for the sprayer.
Would possibly need unlock codes for section control or would it still use the teejet section control?

No unlocks needed for nmea, just a cable either out of the back of the CFX or from the diagnostic port on the nav controller.

Look on the back of the TeeJet screen for a 9 pin DB9 socket, you need a cable to go from this to the back of the Trimble screen, which will be a Deutsch plug. You only need 3 wires of the 9 pin plug.

Cable like this:

FMX/FM1000 and CFX-750/FM750 Serial Output Cable, DB9F
