* Albrecht AE-60T Scanner===discriminator tap===Using a discriminator tap gives you access to the scanner baseband audio.  This unprocessed audio is necessary for digital decoding and other related things you can accomplish using computer software via the sound card.  The receiver IC is a JRC 3359. The unfiltered discriminator audio can be found on pin #10 of IC #3, 3359DA.  Pin #10 is on the top right corner of the chip. Solder to the lead to the resistor at TP3 which is connected directly to PIN #10 of the IC.  You should put a 10K ohm resistor in series with a 10 μF tantalum capacitor to protect the scanner from short circuiting. Connect the (-) ground wire to the chassis. [[File:jrc3359discriminatortap.jpg]] More on the purpose of the 10K resistor: Connecting or disconnecting an interface to the discriminator output might cause a short-circuit. The limiting resistor prevents the discriminator IC from being loaded or damaged. Further to that, it prevents your PC's microphone or line input from being overloaded.
