Hi,

I've done the modification. After connecting MIC input to the modified jack I can hear noise on the headphone connector, even if squelch is not opened.

Have you noticed such issue? How to remediate that? Insert an op-amp between the DISC pad and jack output to separate discriminator?

And also, increasing volume of the scanner, the amplitude of DISC signal is also increasing. Any ideas?
