Question: Discriminator output for Uniden 8500 xlt
I found two webpages dealing with getting baseband
audio from pin 9 of IC mc3361. One instructs you to put a small capacitor in series with the lead coming from pin 9 and the chassis connector, and the other instructs you to put a resistor in series and put a capacitor across the chassis adapter lugs. Which method is correct, or can you do either of these? |

Either

If you use the resistor/capacitor method, don't change the values - the components constitute an audio filter, and you don't want to filter out those frequencies you're putting in the tap in order to get. If you just use a capacitor, almost any small one (but not too small) will do, since it just isolates the scanner from the external circuit. |

Thanks for the replies, I will probably use the
capacitor method. |
