Flying off-shore today had a bit of a pucker experience. Using a P3P with a Itelite DBS02 mod. At a little over 5800 ft distance – lost signal. My usual experience (admittedly rookie) is that the image transmission signal gets weak first – I go up in altitude a bit, get signal back – and use that as the edge of my flight envelope. No problems. I usually keep it within about 3/4 mile – but to get the shots I wanted today I had to push the envelope a bit. Today lost image and RC signal together – message flashed up that the quad was RTH. OK. Around 5200 ft out image popped back on so I killed the RTH – pulled back to within 5000 feet and started taking pictures. Then lost image and RC together again. No RTH message . Time passed – and then some more. No sign of the drone - my spotter was asleep at the wheel – I’m puckering up pretty good. Was in auto mode for channel number – switched to custom and set a strong channel – image and RC control snapped on instantly. So –looking for insight on optimizing signal strength Does setting a custom channel or using the auto mode gives best results with the Itelite antenna? I had thought the auto mode would automatically be finding the strongest channel -didn’t seem to be the case. The 32 channel hack might help but have also seen posts by credible folks that the Itelite is not compatible with the extra channels. Have looked thru the threads and get conflicting info. Apologize for the long message.
