Inside the sat-finder

Being a curious "animal" decided to have a look inside the sat-finder, probably the only equipment I own that never had been opened for "evaluation".
Here's the outcome:

There's some common components an LM358 opamp and a "C1C" component I could not identify or find info about, probably a dual diode or some transistor but it's marked as U1... so it could be also an IC. It's for sure the first stage for measuring the signal from the line.

Found very few schematics about sat-finder but here are some links:

This one also used an LM358:
Homebrew but it could be very close to what's inside..

and this one:
