Playuavosd is easy to be interfered

[LoveFpv]

I have gone fly a few times and once the plane is above some urban areas, the osd restart infinitely. Can someone help me with the problem?

Can you show us some video?

Maybe next time cause I did not record it. As far as I know is like whenever close to some cell tower, the osd just restart: the osd info disappear and sometimes the video signal also reloads. I guess whether it has to do with power supply. I connect the given connector directly to pixhawk UART port the 5v power is from this. Not sure if this can cause the power supply not stable. If so, how can I refine it?

When PlayUAV has a serious problem, it is more likely to crash totally than restart. So it does sound more like a power issue to me.

You could try hooking up a 5 volt UBEC directly to the battery, and powering the PlayUAV directly from that. Here's just one example; I've used a number of these. They're cheap and decent quality in my experience:

Loose connections have been the cause of many mysterious problems for me, so that's always worth a serious look too.
