VP2/Vue wireless 'channels' are just different time delays on the same set of frequencies. The only time that changing channels helps (other than by coincidence) is if you have another Davis station within range broadcasting on the same channel.

First step in trying to troubleshoot reception issues is to look at the average RSSI value for that transmitter. See the top right parameter (4) in the second wireless diagnostic screen - https://www.manula.com/manuals/pws/davi ... monitoring might help.

Coming back to this.. I have done so many things to try and work out why I have been getting so many missed packets, and CRC errors, but to no avail.

Yesterday, for example, a total of 540 missed packets and 212 CRC errors, which is pretty bad. RSSI for the ISS shows many dashed out updates, and lots below 20. The console is only about 60' from the ISS and only a window separates them. I always had a value of 50 - 59 before the problems started, so I'm starting to wonder if the ISS is beginning to pack up?

Have you checked the ISS board for water ingress damage?

Since midnight I have 237 missed packets and 147 CRC errors. Percentage of good packets is 98%.

This is from two transmitters - ISS and anemometer. I never concern myself with anything other than overall good packet percentage. What’s yours?
Cheers,
Ray, Cheshire.

Maybe check the corrosion around where the antenna sit onto the ISS board is a little solder joint if you take the ISS board out the turn the board around you will see a solder joint sometimes I've seen them break up

I've been keeping an eye on things for now, but I did spot something weird..

At 12pm the total missed packets was 176.

At the next update, 15 minutes later, that dropped to 152. How is that even possible if it is a running total?
