Thank you Albert H and Yellowbeard. As suggested, I've read Nrgkits.Nz thread and learnt how to make RFC1. As for FRB3 and FRB4, I will wind 10 turns on my 1X9mm ferrite rod.

Should I understand that, since coil between collector of 1947 and supply line is not critical, matching circuit depends almost exclusively on the LC network between the collector and the RF output?

yes they are only chokes even a molded 10uh will work in worth case vk200 but depending on the space ,shoot up a picture to see what you are inventing ,i think you copy the wideband nrgkit amplifier stage ?

I'm just looking if I can have all the components needed to make an exciter close to the PLL Pro III. As I mentioned before, the difference will be the oscillator stage.
