Baroclinicity Posted June 3, 2011 Share Posted June 3, 2011 Anyone know what's causing the persistent spokes to appear on the LSX (St Louis) radar? They are appearing at 310 and 68 degrees with a weaker spoke at 335 degrees.Can't recall when they first appeared but it seems like they've been there for a while.

wxmeddler Posted June 3, 2011 Share Posted June 3, 2011 Is it just on the base scan (0.5°)? Link to comment Share on other sites More sharing options...
Baroclinicity Posted June 3, 2011 Author Share Posted June 3, 2011 Looks like it's only at 0.5 degree. Link to comment Share on other sites More sharing options...
thewxmann Posted June 3, 2011 Share Posted June 3, 2011 I've wondered too. Some of the older data from the 90's also show random spokes. Link to comment Share on other sites More sharing options...
SunnyFL Posted June 4, 2011 Share Posted June 4, 2011 A radar tech told me many of these are wi-fi transmitters. Remember, radar receivers are VERY sensitive. There's no FCC regulation of wi-fi and they are popping up on many radars. Link to comment Share on other sites More sharing options...

Calderon Posted June 15, 2011 Share Posted June 15, 2011 Response from their office: nwschat.weather.gov/NWS St Louis 5: Hi Beau. Sure, the spikes are being caused by 4G wireless internet cell towers that are slightly out of calibration. We're not the only radar that has these spikes...though last time I looked we might be the worst. Technicians from the Radar Operations Center are working on filters for us and the other affected sites. Hopefully we'll have this problem solved in the next 60-90 days. --Jon hmm, then Jax has had a 4G problem since last fall. good to know Link to comment Share on other sites More sharing options...

When I was in StL last weekend there was very widespead 4G coverage by Verizon. Link to comment Share on other sites More sharing options...
