i think XXL is using fake transistor ,a look to what he said is a good idea .
2n2219a for this work ? as his FT go to 250 mhz

No Worries! Thanks for the PM :)

I have not used the 2N2219? But i dont see why it will not work? Maybe some tweaking might be needed?

Band 1 being quite low in terms of frequency range may even permit the use of BC547s?

The oscillator is easily built on a copper clad board if you wish to experiment!
I am as stupid as I look! :|

No i did not build it yet :) it will take some time.Yes simple as is and brilliant no exotic components,and if well done must work from the first power on ,what value for the POT trimmer 10 k or ? yes it is not critical ,but what is best .
