You are a guru not me, so if you want you can add a fine tuning at this schematic for 5Khz and 8.7khz.
This can be your help in this project.Wait until the end....
I told you there is another device in this but we will talk later .First step build this ,make the improvment ..and see.

Hi Alex,
To be a guru you only need to talk a lot, this doesn´t mean you´re good at it
Anyway i will try to make the PCB, i will post it a soon as i can.Switches and leds will be out of PCB.For R4 (2X 4M7) + (2X 6M
should be OK.
I assume L1 and L2 are 1/2W size or so.I don´t know exact pinout of F1(fet), but that should not be a problem.
regards,
Fred.
