"Thanks Tridge,
I might as well give it a go and see how much of a problem it is. I'm guessing it will limit the air rate mostly?
Anyhow it doesn't save the config. I must have the wrong firmware version. Is there a binary file I…"

"Hi Minh,
If you mean you have a 915MHz radio and want to run it at 868MHz, then for it to really work well you'd need new hardware. The 868 modules have a different analog stage than the 915 modules. If you run the 915 radios at 868 you will…"

Can this update be done with a bootloader and .hex image? I don't have the programmer and would like to change frequencies...

"Hi Andras,
After seeing this posting I have added the 470MHz and 868MHz register tables to the SiK firmware. If you update to the latest 3DR radio firmware you will get full support for your 868MHz radio.
Cheers, Tridge

I undertand I can make a very good modems with the bootloader and the firmware.
I have been using APC220 433 radio modems. but I would like to fly with 433 RC and I would like to use these modems. When I used the APC 220 I think they…"
Andras Schaffer replied to Andras Schaffer's discussion Using 868Mhz modules : Success"Hi,
HM-TRP modules are work as a transparent comm module by default, BUT they are NOT 3DRadio modules. To use them as a 3DRadio module, you have to program the appropriate bootloader and the firmware. To do that you need a C2 programmer (to program…"

Here is a short video of poshold (loiter) in strong wind.
During the last two months I was working on the RTH and poshold code for MultiWii, which is finally released some days ago with the 2.1 release. The code is mostly based on the ArduCopter RTH and loiter code, with some optimization and tailoring to fit into an atmega328 controller.
I followed the…
