Saving APM settings on mission planner, can we?

Started by Michael Withington. Last reply by Hotwire Apr 20. 3 Replies

Giddy everyone, I heard it was possible to save an APM settings on mission planner so that it's possible to use them again on another APM or maybe a pix hawk? Even just to back up the data settings,…Continue

Just want to let people know that as of today, the Solo is now available for preorder in Australia from here

Are there any multirotor racing groups in Sydney or NSW??

If so does anyone have any contacts?

I just wanted to know if anyone has info about the idrone device from fighting walrus. Will the 915Mhz work on a RFD900 or will I be waiting again for another version for RFD900.

Hi Fred, I think the USB radio uses the FT232R chip

So if you unsolder pins 1 and 5 on the chip you can connect wires to the pads on the PCB and solder these wires to the TX and RX pins of APM.

So, yes techincally possible, but not something many would attempt. I run the RFD900 modules, so I can't check one physically. Maybe there is a breakout connection somewhere more convenient on the board?

Hi all need little help as always only on  weekend getting ready go out sunday

my Telemetry air side has died on spares can i convert usb module to air radio ?

Yep, Tim it's exactly the same document. Smug rights are all yours.
And your right again. You would need an antenna of a gain greater than 10db to get yourself in trouble with the 3DR 915 at maximum output. That's another reason to get the 915 over the 433.

At the risk of sounding smug, that ACMA document is precisely the one I linked to previously...

Warren, your EIRP point is a very pertinent one. However for the 3DR radios at least, they max out at 20 dBm which is far below the 30 dBm threshold with a vanilla setup.

@Mitchell Berry: Radio Amateur take undertake study of how radio transmission work. How to build antenna and how to detect and mitigate the reception and the transmission of radio waves on unwanted frequencies (interference). Due to this expert knowledge they are allowed to do more with more power. 

They still have a non-commercial license, and the expectation to help with communications in emergency situations.

Supposedly you are allowed much more power from 433MHz with an amateur radio license.

I can't actually work out what a licensed radio operator does that makes them more capable of using that band? Is there some sort of CB frequency to announce your intentions to other people around? Doesn't make any sense to me.

Comment by Warren Eather on March 16, 2015 at 9:35pm
Thanks Hotwire, that's a good document.
It's important to note that the maximum power stated refers to the Equivalent isotropically radiated power EIRP, that is transmitter power + antenna gain and not just the transmitter power.
So for example if you had your RFD900 and a 3db antenna the maximum transmitter power setting to achieve a EIRP of 1W or 30dBm would be 30dbm-3db= 27dbm = 500mw that's half power!!
