The output of the tuner IF (6Mhz bandwidth) goes to the input of the log amplifier where it's amplified and if any signals are detected the poutput of the log amplifier sends it to the output pin on the tuner
I guess I'll just have to wait until the tuner arrives, swap the demodulator for the log amplifier, connect a 385Mhz antena and see what the output is when it detects a signal by connecting a volt meter to the output pin, I don't have a scope.
