20w 2m rf amplifier

I built the PA board for this when I was a foundation licencee, but under the foundation licence, you must only use comercially made transmitters. Since getting my intermediate licence, I have put it in a box, and added an RF sensing switch so I can use it. It uses a 2N RF transistor, and will produce 50w output max. It is a class C amplifier design, and therefore good for FM mode only. I have tried using the 2N in class A, but amplifier gain was down to about 4dB and it seemed a but pointless! Yes, you should get around 30w at the antenna with 7w input to the amplifier.
