The only way to really know is to use swr/power meter.

The setting depends on frequency, supply voltage and bias adjustment
so you can't say accurately from number of squares.

So i must have an SWR meter to know the output?
Is it not another way to do it? Turn down the voltage on the power supply? SWRmeter cost a lot here in norway. :roll:

I need 1w to drive the 40 amp. :)

Start from zero and go up until you get 40W from the amp.

Again you need swr meter to see 40W.

You will need swr/power meter at one time or another,
I say get one, the sooner the better.
