Sure, her we go, and it gets interesting!

Renato, costi_n, futurebreze you guys were right, the datasheet is wrong, so was I!

Scan of tx with all connections left open (floating) reveals it in fact transmits on 5945Mhz, alas channel 8.

Lesson learned, you have to doubth datasheets from chinese vendors....

OK, fair enough, I was going by their pdf data sheet as well.

Should we put this down to Chinglish interpretation again

Lesson learnt.

the datasheet is right: 0 means ground, 1 means open... so 0-0-0 = 5.705...

Anyone know why my system is not working with the 470uf cap ? I use the 200mW SkyRF TX module from foxtech. The system is running good and the picture is not that bad. But I want to build in these caps for best picture.

I soldered the cap between the GND from the 3,3V UBEC and the GND on the module. Any ideas ?

Ooouuuppsss ?!!!
How this ?! The two grounds must be soldered together, and cap is between plus and ground, not between grounds !

Nice. Good job.

But or LCD is too small and too low resolution?
Suitable for FPV?

make yourself a cloverleaf and SPW antenna and you will have a great cheap kit.

I don't own any tools for analysing the frequency, etc.. And I guess that your put the cloverleaf on the TX and SKew on the RX?

Not need, if you have good soldering skills and are precise with distances, angles, you have from scratch better results than stock antennas without any tuning.

Yea I read the Cloverleaf tuto from IBCrazy. The only thing I don't understand is how you determine if it's right-hand or left-hand...
