Discriminator tap for BC895XLT Needed
Can someone tell me the proper tap off procedure for the BC895? I have
found-I think-the correct tap off point but the audio is severely affected on speaker output if I feed it to a sound card. Steve |

According to http://www.discriminator.nl/ic/ it should be pin 9 of the MC13371. Did you tap the right point? -- Cabin crew: yellow door selectors automatic |

not sure, but THANK YOU for the info!!! Do I need to use any dropping resistor or make up a network to isolate it from the sound card input impedance??

Do I need to use any dropping resistor or make up a network to isolate it from the sound card input impedance?? I always use a resistor between 5k6 and 15k, but that's merely to protect the discriminator output from short circuiting during (un)plugging. Rene -- Cabin crew: yellow door selectors automatic |

To be precise, I should write that I use a resistor to protect the receiver's discriminator when the output is short circuited during (un)plugging. -- Cabin crew: yellow door selectors automatic |
