Re: no TX power on any Band and outside the Band

Andreas,
You have to take the machine apart and test the final transistor. It is sandwiched between two boards. It is best to change the device anyway since you are already there. Clip off the old transistor while on the board. Then desolder the old legs. Test the transistor to find the fault. If it is OK replace it anyway, and move to test the pre driver. Most cases it will be the final transistor.? Don't forget the jumper boards are polarized, mark them before you take apart.
Nigel ZL1NAY?
I get myself a used x1m today and it has no output power at all, I can here the signal on my sdr sitting next to it, but got 0w on my swr and on an atu100, maybe someone no were I can start to search the error?
I put on March 14 firmware but nothing change.
