About Me:

EE by trade I design embedded software and hardware. My two daughters (22 & 19) don't have much interest in my hobbies.


Please tell us a bit about your UAV interest

I fly helis quads and plane for fun. So next logical step is UAV I do construct test and fly Quad and hexacopter from scratch. Use APM 2.6 and 3.1.X copter software. Use Mission planner but will switch shortly to Pixhawk I think.

433 would be the best choice.

on 433 MHz, all the cranes, heavy vehicles, earth movers two ways radio are "pumping" tens of watts so not automatically the best :-)"

"Hi,
Which board version are you using? (1.3 or 1.31 or ..?)
Which firmware is loaded on that board? 2.11 or.. ?

Seems you have something real wrong very possibly in the firmware area.

I am struggling too but for different reasons. (don't want to h…"

"900+ and 900X are not compatible. I do have multiple pairs of each.
The biggest advantage of the 900X is its fast processor which let ECC work without any lag.

Cheers

"@Navigant 
Long story short: This modem can be powered independently (5Volts) from a separate cable. So this is a direct solution to your question.

"@benny arisusanto: Yes indeed! :-) RFD 900X solved

That is very encouraging . I'll measure the lag time on CPPM signal with a scope and will report the values."

"Perhaps I would be better asking rfdesign.com.au to exchange my rfd900x set of modems for 900+ ones? (At least the 900 and 900+ sets I have work great with mission planner.)
Don't need encryption at this stage,

I have air-frames grounded because of…"

"Not only the RFD900 modems are reliable but are a direct fit with Mavlink. I do have used a dozen of them now without a glitch!

It is better to give them a 'clean' power (5 Volts) as it seems to connect better.

The service provided by rfdesign is…"

Any 12 Volts to USB (Which is 5 Volts) normally will work.
So a 3S Lipo battery when fully charged is (4.2 x 3) = 12.6 volts.
