Novice or not, you might as well learn how to do it - after all we would have to follow the same proceedure...
Start by downloading the DATASHEET for the NE567/SE567. There not only you will find sample application notes but also the way to calculate the Centre Lock Frequency and so determine the values for the appropriate components. Give it a go.

My signal comes from telefon line
My signal is comming from telephone line.In turkey (if u want)they sent 12 KHz on each kredit finish.For example 1 minute left they sent 12 KHz from the telephone line.I found a shematic for the phone line.When i buy the materials i will try this shematic.
Asking is not a shame but not learning is a SHAME!!!
