I tuned my MAX PRO 3 to 100.9 MHz, but when i search on a car radio it show 100.85MHz.
How can i fine-tune this to 100.9MHz?

Look at the manual, there is a trimmer on board and it is all explained
in the manual.

We have invested a lot of time into writing these things, but it seems
sometimes that nobody ready them.

I have another problem, the signal was poor and just transmitt a few meters.
I don't have the LCD panel, i set the jumper i PO 2, no signal come.
I don't find out of it.

Rotate trimmer to adjust power.

I hope the extra trouble you're having with jumpers and switches
is worth the savings from not getting the LCD module as well

Sorry, I am just being a bit naughty today

When i have jumper on ''LCD'' it work and the transistor get warm. When i move it to P2 it transmit for a few meters and the transistor is cold.
When i turn the trimmer nothing happend.

Its multiturn, you need to turn it for a while and in the correct direction.

to left og rigth to get more power? Look at the picture
And must the jumper be placed on LCD or P2?

If you don't like trimmer, you can also try 1K potentiometer.

how long must i turn it to get full power? 15w or 20 w?
I have turn i for while and it come a ''click'' from it when i have turn the screw 360 degrees

It is about 10x 360degrees to get a full turn.

And then i will get full output?

Or is it 10 x 360 degrees = 1W or someting?

its a multiturn precision trimmer, there is no scale. Turn it one way and power goes up, turn it the other and power goes down. Most people prefer to set power and frequency via LCD display. In some cases they also use potentiometer, which can be connected to the board via 3 provided holes.
