K3 bad TX - solved

[Toni Lindén]

Just to let you know that spurious signals while TXing are gone ;)

The problem was capasitor C3 that was soldered on PA board. That
capasitor should not be there and causes an oscillation in the bias
circuit.

Big thanks to Frank, W4NHJ for helping me finding this out. Also
thanks to everyone for other solution suggestions and help!
