Rubens,
Suggestion, verify that the receive function works, then try the transmit function without the power to the PA connection.? You should be able to verify the bias settings as being adjustable from 0 volts to 4 volts or so.? The bias is only applied when the PTT or CW ket is pressed.
I would also check to see if I am getting a drive signal at the gate of the finals.? I did this on my uBITX using an oscilloscope.? I cannot find the pictures I took, and need to run out and get food.? Will check again later.
