Graham Abell replied to befinitiv's discussion 3+km HD FPV system using commodity hardware
"Missed this, apologies. I only tried them in 2.4G but they worked fine. I did pick up the adapters befinitiv recommended since he'd done the work on patching their kernels and I wanted to minimise differences from the base platform. "

Graham Abell replied to befinitiv's discussion 3+km HD FPV system using commodity hardware
"I'm using RPI2s with no problem (same dongles)... I don't see any massive improvements compared to what befinitiv has documented. I saw openfpv moved from rpi to Odroids but haven't seen any updates on that project in a long time."

"Fair enough. Could you elaborate or point me to how you identified jamming? I could then see what makes it improve. Thanks again. "

"Thanks for looking Paul. What should I be looking at hardware wise? How can I shield the GPS from jamming?"

Graham Abell replied to Randy's discussion Copter-3.3 beta testing
"I was in open space with nothing in the way, I was basically in a big field. I enabled that logmask and replicated the scenario in my back garden, this time I could only get 5 satellites and HDOP was higher at about 3.8 or so.

Graham Abell replied to Randy's discussion Copter-3.3 beta testing
"I powered it on and left it for about 20 minutes at one point to see if it would get better but it made no difference, I had about 6 satellites on average and a HDOP <2. The tower app indicated a 3d lock but when I tried to arm in poshold I got the…"

Graham Abell replied to Randy's discussion Copter-3.3 beta testing
"Has something changed in relation to GPS locks? I was out today for a test flight. Telemetry was telling me I had a GPS 3d lock but if I tried to arm in poshold it failed with a GPS lock required warning. Similarly if I took off in stabilise and…"

Graham Abell commented on Tilman Griesel's blog post OpenFPV Update 2 - Roadmap for 2015, Oculus Rift Support, 5GHz
"Hi Tilman, 

Good to hear things are still progressing, there's not much that can be done about the weather - we have the same problem here (Ireland) although it's starting to get a bit better. I look forward to your next status update!"

Graham Abell commented on Roberto Navoni's blog post The new plug and play VRX GPS NEO-M8 MULTICONSTELLATION (GPS , GLONASS , GALILEO) with HMC5983
"Is there a case/shell available that will fit this module? Also, it seems like the connectors are on the back side pointing down, does that not make it awkward to fit it?"

Graham Abell replied to Graham Abell's discussion APM disarming after a few minutes flight
"I seem to have made some progress. I dropped the land voltage to 10v from the default 10.5. At 10v finish I'm using too much mah though, around 4300mah, I think if I up the land voltage to 10.1v I should finish with about 1000mah to spare which…"
