Hi
I built a stereo encoder based on this project
https://pira.cz/eng/stk2en.htm
However, I have a problem with channel separation, it doesn't want to be better than the 35dB channel separation. This is not a problem of the receiver as it has a separation of ~ 43 dB (measured on a professional generator). What could be the problem?
I am attaching the eagle drawing.
thanks in advance for your comments and help

The photo you provided isn't particularly valuable. Let's get a little more specific.

I also have a problem with demultiplexing, it doesn't want to be better than 35dB demultiplexing. I don't know how to solve it?
