My little UAV project is a nightmare. After many years of trying to get both telemetry (GPS, altitude...) and live video to work simultaneously on my R/C glider, I finally have current and working equipment but....
If you really want the back story, I'll post tomorrow...
The short of it:
I briefly had both video and limited telemetry working a couple of months ago, GPS failed. The setup didn't have any real interference issues. Two 900 MHz transmitter antennas within 6" inches of each other.
Last night I replaced the Tx and a recorder unit. The recorder has some static instruments on it, but does not transmit a radio signal, it's the hub for all the sensors/inputs and can record the data. The Tx plugs into this device.
I ruled out the GPS as causing interference.
Somehow, I think the recorder is the culprit - receiving interference from the video Tx. I switched out the new telemetry Tx for the old one and the same problem. The telemetry receiver loses the signal. Unplug the video power and the telemetry comes right back. I have tried separating the Tx's as far from each other as I can, with the same result.
Any ideas, thoughts? I was planning on being at the field at around 9:30 in the AM...
Thanks!
