Put 2 10pF in series. Or two 2.2pF in parallel.

Take a small piece of insulated wire, twist for about a cm and cut off the end. You have a small coupling capacitor. Decrease the capacitance by cutting off more of the wire until you have the best performance. Since the purpose of this capacitor is to provide loose coupling from the oscillator to the RF amplifier, the capacitance is not as critical as it would be in a tuned circuit for instance.

No. My store (argus.lv) doesn't carry these at the time.

It doesn't surprise me.

I go to a number of different stores and I still buy online for a lot of things.

My guess is you are from the old USSR?

I wouldn't even hazard to guess what you can get shipped in.

Have you tried salvaging from old electronics?

Its there, circled in red. What do you mean "you can't find it" ?

Its a 4.7pF cap, a 3.3, a 5.6 will work fine

I guess he means that he can't find it in his scrap box.
Maybe because a lot of them are color coded or without any markings.
Sometimes there is no other option than to actually buy something ;)
