I am building a circuit which requires a 2pf ceramic capacitor as well as a 7pf ceramic capacitor.

I cannot find these values, the closest I can get is 1.8pf and 6.8pf.

Will this small difference in value make a difference to the circuit? The circuit in question is a model rocket tracking transmitter.

 

The wrong capacitor values might change the frequency of the transmitter if it doesn't use a quartz crystal. Then maybe the coil can be made with its turns a little closer together to get the correct frequency.

Thank you for the info.

This circuit does not use a quartz crystal.

So if I understand it correctly it will still oscillate, but the frequency might just be off? That is great news, I have a RF sniffer/freq counter that I can use to check the output freq.
