Briefing: https://www.casa.gov.au/publications-and-resources/standard-page/ca... aircraft are a hot topic of conversation in aviation circles around the world. Remotely piloted aircraft systems are here now and we…
"hey, did you ever figure this one out? I'm interested in the same thing.. cheers!"
"yeah, it's a real shame that you can't get stereo audio on the lower freq a/v transmitters to run telemetry. I'm looking at moving to 900mhz a/v (mono audio), 433mhz RC, and with APM 2.6 and the 3dr radios sufficiently off my RC freq, like 470 or…"
"few guidlines to long flighttimes:
super light frame, the bare minimum you can get away with
the lowest KV motors you can afford
the biggest props you can fit on the motors
the most energy dense batteries you can find
Even then, the record is…"

"Thanks for the write up, interesting reading."
"the next order I do from getfpv I'm going to get a whole swag of rp-sma to sma and sma 90 degree connectors so I can mix and match everything, being stuck on linear polarisation at the moment because of incompatible antenna connectors is such a…"
"keep in mind your phone has quite a few standards to choose from with different frequencies and data rates,eg these are for the LG Nexus outside USA:
GSM: 850/900/1800/1900 MHz
WCDMA: Bands: 1/2/4/5/6/8
LTE: Bands: 1/3/5/7/8/20
at 850MHz your…"

"My wife gets annoyed every time a new package arrives, I'm starting to quietly put them aside and put them away in bits so she doesn't notice ;-)
I haven't got FPV working yet, I think pan/tilt is a fair way off yet for me, but I'll be happy just…"

"Cool. I haven't looked a lot into antennas at 433 and 915 as I won't be able to use them for a while. Everything is so big at those low frequencies!"
"which antennas are you using, a large whip on the UAV and a patch on the ground?"
"yeah, I've been looking into it, there's a book you purchase and study, then your local hobby group invigilates the exam and you get your amateur licence and your very own callsign! then you can go on and do intermediate and advanced, Advanced can…"
"Just as a wild guess, I'd say its because the transceiver towers that your phone talks to push out hundreds of watts, and they have massive high gain patch antennas on full 360 degree coverage. If you could mount that transmitter on your UAV and…"
"You're right, I do recall reading that somewhere. Thanks!"
"Really? I was under the impression that the telcos owned the frequency around 900mhz for 3g etc? I could be wrong..."
"Depends, do you have an amateur radio licence? If not then technically neither. If you do then I think you can use 433mhz, but you might need the intermediate or advanced licence. Someone more knowledgeable than I could probably say for sure..."
"Shame that electricity prices there are so high :-(
On a different topic, how is the Energiewende going?"
