I’m pretty much done with this project so it’s time to formally document it. This project is a collaboration between Fred, KJ4LFJ who supplied the hardware and myself, Scott, KJ4LDF who supplied the software. Briefly, a scanner is set to a single frequency (147.120 MHz, the output of an active repeater in Orlando, FL) and the audio output is fed into the microphone hole of a PC sound card. The scripts below (run in the order they appear) detect audio activity, log the data, and display such data graphically. Here is some sample output:
test_24hr-1
test_average
test_alltime-1
test_60min

Live-running software is current available at: Fred’s Site. The most current code can be found in its working directory. For archival purposes, I’ll provide the code for pySquelch in ZIP format. Now, onto other things…

What type of hardware are you running this program on? How about the scanner? Is this program specific to a certain type of scanner or can it work with anything?
