filters for GPS and 2.4GHz

Recommended Posts

I am running 4W 2.4 Ghz TX within 10 inches of GPS reciever. There is an effect from video TX on GPS sensitivity but GPS still works, I may loose couple of sattelites when video is operating.

I'm curious, at what power output will a 2.4GHz transmitter start overloading a GPS receiver?

Depends on distance, GPS receiver type, age of the operator...

Can't give a general figure for such a thing ;)

age of the operator...

:lol: Don't you mean "experience"?

I'm planning on using some amateur ATV transmitters, one in the 70cm band and a second one in the 900MHz band.

Each Tx will be putting out 500mW. I think I'm safe.

I have been fooling arround with this for a few days now.

finally I am happy about the result.

I forgot to say this the first time around, but I really like how you sandwiched all the boards together into a small package. That OSD you built for telemetry is pretty cool too. I wish I knew how to program PICs and make my own OSD.
