We are experiencing issues with our Reach RS3 when receiving corrections from a Trimble NetR9 base. At short distances, it works reasonably well, but beyond 1km, the signal frequently drops or becomes unstable.
The base station appears to be working correctly, as confirmed with an R12 receiver. Additionally, the UHF radio is properly connected and configured on 426.950, and the bandwidth is set to 25KHz. Given these factors, we are unsure of the root cause of the issue.
Attached is a screenshot of the base configuration for reference. Could you please assist us in troubleshooting this problem?
Thanks for the details! A 1 km range with UHF indeed doesn’t look normal. I’m here to help figure out what’s going on.
Such issues are often related to local environmental conditions. I see you’ve tested this setup with the third receiver, R12. Was it able to maintain stable corrections over UHF beyond 1 km? If so, it makes me think there could be an issue with the device. Still, I’d like to double-check any other possible reasons for this behavior.
Could you try running a test using firmware version 33 Beta 1 in the same area? This version includes the signal strength indicators. It should give us a clearer picture of how stable the UHF signal is on the RS3.
I have NetR9 and UHF, are you able to post the relevant base I/O Configuration Serial page settings, and your radio model and its config?
And apologies for the practical questions but these are key ones under the circumstances and yet to be confirmed, are you using the optional (~32cm) RS3 UHF antenna?
And double checked it’s properly attached? Should thread on very light to touch but can be tricky to initially line up correctly without cross threading due to obstruction of the rubber flap.
