Re: 9Xtreme speaker hiss

Try decoupling the power supply with a 10mf and a 10nf at the amplifier, that will probably work.
The low impedance output of the amplifier probably excludes pick-up between the amplifier and the speaker.

Re: 9Xtreme speaker hiss

Perhaps a signal diode in the pre-amplifier stage (as used in the original Dolby systems to give a noise gate for hiss) would work, is there a published circuit diagram?

Re: Programming 9x with USBASP fails, works with Arduino

Depending on your operating system you will need to load drivers an example of how to do this:

For other operating systems you may need other drivers.

Look for someone using 2.4GHz for video it uses a large part of the bandwidth that's why you can't feasibly use 2.4 GHz for video with 2.4 radio.

Re: Turnigy 9x on Safle Flight Apprentice Rx

It says it fits the Turnigy, and is DSM2 / DSMX , so yes. You will need to remove the existing module which has an aerial wire leaving from the back of it to the internal antennae (if its the version sold by hobbyking). You can just cut the wire if you don't intend to use the module.

Re: HP llap top compatability

I had a plug power supply rated at 12vDC but for some reason I checked the voltage and it was 16Vdc. I did not check it under a load or use it.
An unregulated power supply will float up to a higher voltage with no load.

Re: HobbyKing now offers 9x mainboards and LCDs as spare par

Hmmm... If they have Atmega128 right from the factory, these boards will likely suffer from the horizontal trims issue. So a Ground Fix mod must be done by the user as described in the wiki before using 9x radios with these new boards. Also read this thread: http://openrcforums.com/forum/viewtopic....

It doesn't need to be an arduino a single atmel or pic chip would do the job, the lack of battery however looks a bit suspicious, but with some pen cells or coin cells it's perfectly possible.
