I was hoping that some of you
Davis packet experts could provide some insight.
After running for months with 90%+ good packets per the VUE diagnostic screen, good packets have been in the 45%-63% range very recently. My VUE console that shows the local marina VP2 data via a long range repeater is sometimes showing a
temperature discrepancy vs. what is reported via Weatherlink.com. (I recently fixed the WLIP upload issue over there). I see the exact same temperatures
via the repeater on all my consoles, Envoys, and meteohub/bridge devices.
Normally the temperature has agreed quite well as I recall, especially during high packet rate success.
I know that during poor packet reception that I miss wind gusts, but this makes sense because the samples are being missed. For temperature, this is usually fairly static and I would not expect to see errors. The temperature has disagreed by as much as 2°F recently.
I took a VUE console over to the marina parking lot and configured it for Station #1 and watched the data from weatherlink.com and this console. They matched exactly.
What could the long-distance repeater be doing to introduce a temperature error? I have never seen this behavior before. (although I wouldn't have known from last October to this past week due to the loss of WLIP function)
I suspected and have observed signals in the adjacent 800MHz band (cell and emergency services) on my RF Explorer spectrum analyzer. I do have a BPF with the 902-928 MHz pass-band at the pre-amp feeding the repeater input.
