Yes, it works very well.
It is used by Walter DJ2LF, Markus DF6NM and Roland DL3NDR.  For antenna current of 300mA and PA power of 200W you will have to transform to about 400V.
At the beginning I used a stereo amplifier with 80W. A good way is when you use a car amplifire.

Has anyone tried driving an audio amplifier on 9 kHz and using a matching transformer to step up the normal 4 ohms to 50 ohms, if so what results.
