RF amplifier not working
the RD06HHF1? I could see HVF1 maybe at band III, but the RD06HHF1 is only specified to 30MHz! 

You may want to have a look at the gate capacitance of that RF Mosfet, they are usually not small and need some input matching (Usually at least an L network, sometimes two stages if you want broadband gain). 

Take a look at some of the designs for the 2M band, what you have will probably be unstable if you do manage to get meaningful gain out of it, layout is also everything in RF power amps, and again the ham 2M stuff will show you how it is done (Solid planes and the like).
