I had an issue that developed last fall in the combine with a 2600 display. I would be going along and I would lose all GPS accuracy. It would be gone for 5 or 10 seconds and then blip back up. It would maintain signal, but lose accuracy. It would kick out my autotrac and when it would come back online be off a couple feet. I thought it was the combine harness.
Put the display in the tractor this spring. It's doing the same thing. I grabbed a different corner post harness and different receiver. Still doing it.
Yesterday I was spraying with a completely different display, harness and receiver.
I've tried a couple ITC receivers I've never had issues with and 3000 and it's still doing it!
Now I'm trying to plant corn and it's blipping out all the time and it blips my rate control when it does it.
What in GPS HELL IS GOING ON! I'm about to start driving things off the river bank.
