I lose a walkera TX module due to the experiment.
I think I left it on for too long or some thing. It was collecting
the sequence fine, running for a few days. After it complete the
64K sample and program exit. I find out it is not working any
more the other day.

Long story short. I guess it is the FET that switch the antenna
circuit or the amplify circuit was bad. So I open up the TX
module metal casing. Break the circuit right before entering
the FET. Instead I solder a short wire as antenna.

It actually works. I don't have power amplify any more, but
it can bind to DSM2 receiver. For this test, I don't need to
amplify the TX signal any way because the receiver is very
close. I actually prefer no amplifier because I don't want to
interference with my other heli binding.

So I salvage a $10 part. Here is the picture where I solder
the antenna
