Seems like Radio Interferance.. but is it?

[IainB]

Hello everyone, a newby here with a Maplin W96GY (WH1080) station.
All set up wind and anemometer on the roof, temp and rain in a safer place and website working etc.

I have been looking at the daily graphs for the station and it appears that between 1300 and 1400 the graphs suddenly get really spikey in all areas which continues for the rest of the day, but seems to be Ok again by morning when the graphs smooth out until the same time (ish) the next day. Has anyone else had a similar problem and if so did you detect what the problem was and how did you fix it.

Everything seems to be working fine (no pun intended) its just looks really odd for people who view the site.

I suspect radio interferance from some source, but nothing in the house changes around that time (no heating systems turn on etc).

I have used the forum search for the key words, but nothing came up, so.. over to you.

Thanks in advance

Nearby weather station, same frequency, same protocol? I guess they way to check is if the wind changes faster than every 48 seconds.

It looks like you started Cumulus at 1300, so the data plotted just before that is from the station's logger and/or Cumulus data logs, and hence much less frequent.

You don't shut your PC down over night do you?

Just passing through on my way to bed. Good night, all.

Thanks for the immediate posts. Yes I do close around midnight (as you can see by the time of this post!), but restart at 7.30 each morning.
When you say started cumulus at 1300, do you mean when I first started using the programme on its first log in use or start time each day?
No other stations within 4 miles so doubt that one can be the reason.
Any other thoughts?

Your graph at that time looked exactly as it would look if Cumulus was restarted at 1300 and you were using a fairly long logger interval either in the station or in Cumulus. Just like it looks now, but it has only just started accumulating the 1-minute interval data at the very edge of the graph, as you have only recently restarted.

In a few hours, it will start to look as it did yesterday.
