I´ve been trying to solve this problem in many ways but I just can´t seem to get it right.
I have been flying PCM for some 15+ years. Since FPV, I´ve pushed my PCM to 2 miles in urban environment with no issues at all, very happy with that.
I´ve been listening around and most get incredible range out of their Coronas and also the PPM glitching warning before losing it completely.
Have a new DOSD and also am developing the PPM decoder both which require me flying in PPM mode....
Ordered a new synthesized Corona from HK.
To my surprise, got glitching @ 500 meters ( pretty bad )...
Ground range check is about 30 meters with or without Vid gear.
Switched to a Futaba dual conversion 8Ch.
A bit better but not good. Today I had a glitch when approaching 50 meters from me... Ground tests on the beach with nothing around me was 30-40 meters, and maybe a few more w/o Video gear.
Plane is a wing and RX/TX are about 1 meter apart from each other.
Servos are maybe the only thing I haven´t changed.
TX: Futaba 9CHP - 3s lipo powered. ( could this have damaged my TX slightly? )
RX´s: Corona RP8D1 / Futaba R148F
Vtx: 300 mW 1.2 Ghz
SC2000 690 tvl pixim camera.
what could be wrong?
what are your ground tests results?
