Did you ever get one? I have one schematic that I think came from Turkey, (after alterations), Tim got it for me. Are you having trouble finding stations also? MB

I have attached the image of the schematic (I think) Mine will not receive any stations in the USA, maybe you can have better luck.

Let me know if you received the schematic, and what your thoughts are. I would like a opinion if you see something that may help mine work here in the USA.

Sorry I do not know any more about it than what I sent. I am not a tech or an engineer. The receiver was engineered to receive 44-142 khz, but it needs to be altered or a new module built to receive the only frequencies here in north america (24-25. Cool

It works in the nw of the usa, only because those transmitters are up there (Washington and North Dakota) You might just concentrate on the schematic of the receiver module part, everything else is user friendly and works ok for me.

This schematic is partial and incomplete. I am a tech and this shows a series of amplifiers and a fixed coil but shows no output or other elements of a complete circuit... 9 volt DC...

Oh well. Thought I'd ask.
