Thanks @steve, I remembered seeing about it last year. I hope it’s that simple for him.
It’s a good thought on removing the washer. Support should’ve already been through this with him.
@Wally-schatt, if those tips from @Steve and @cobradunn don’t work, and you’re amenable to doing it, you could check the connection on top of the ECU inside the core to see if the cable is tight or if it was connected to the wrong antenna input by accident. It’s basically 6 screws to remove the shell of the core to check that.
I never installed the rubber washers on my Yarbo’s antennas… And I don’t have any of the RTK issues that others sometimes experience. Coincidence?? I don’t know. But I’m not planning to ever install those rubber washers.
Hi Steve, Thanks for the suggestion. I had already tried removing the washer. I also replaced the entire antenna on both the core and DC.
I did check this during my initial troubleshooting. I also connected the antenna directly to the ECU to see if the signal improved. There was no substantial difference. Also, my HaLow did work great for several weeks before this problem appeared. The ECU port was labled “HaLow” so unless it was also labeled wrong, it was on the correct port. Thanks
Yes, I remember you saying that now. That was actually a really good troubleshooting step that I hadn’t considered (eliminating the wire and putting the antenna directly on the ECU). I’m assuming your replacement DC antenna yielded the same results?
Crap. Worth a shot. 
No significant change with the new DC antenna. I also tried putting the old DC antenna on the rover but no change.
Definitely sounds like a hardware issue but the question is, where? DC or Core?
Really sorry for the delayed response. Could you please move the Yarbo as close to the Data Center as possible, and let us know through your support ticket once it’s in position? Our field service engineer will continue with the next diagnostic steps as soon as possible after that. Thank you for your patience and cooperation.
Update:
FSE has determined that the DC is faulty. They are shipping me a new DC. Fingers Crossed!
Glad to hear they figured it out. Hopefully you’ll get the replacement soon.
I hope this resolves it and they did actually identify an issue and are not just swapping out parts starting with easiest one first.
You must be psychic. It might be marginally better but I am at -78db with the core about 150’ from the DC. I am able to get HaLow to connect in some parts of my yard whereas before it never connected. I’ll update the ticket and see what they say.
Update
I reported back to support on June 4 that the new DC has not fixed the problem. On June 22 they finally replied telling me to just use 4G and then closed the ticket. The 4G data limit doesn’t last a whole month so I had to pay for my own data plan with unlimited data. Even worse is that Smart vision still has a time limit even though I’m not using their data.
I’m thinking it’s time for a refund. I don’t know what else I can do. Anybody had luck getting their money back?
That is an absurd response from support. I would drop your ticket number here for @Yarbo-Forum to address it.
Agree with @bryan.wheeler. That is not an acceptable response. Don’t let that stand. @Yarbo-Forum, what is going with these responses?
I think they are being pressured to close tickets fast. Not a good thing.
Hi there, I’m really sorry about this. I’ve already asked the FSE responsible for your case to reinvestigate it as soon as possible.
