DCF77 Time Code Receiver with a U4224B

DCF77 Time Code Receiver with a U4224B

(OP)
Hi,

I've designed a receiver module, using the U2442B chip from TEMIC Semiconductor. I can now receive and decode the DCF signal from the German emitter, that's great....
My problem is that I'd want to display the signal reception level and I don't know if it's possible with this kind of component.
I've already tried to measured the signal from pin INT (with a meter input resitance >1Gohm). The signal on this pin is supposed to give you a DC signal, function of the signal reception level...but I don't have any results ...

If you could help me to find a solution it would be great,

Thanks,

Best regards.
