# CSDR-AM
|
|
|
|
The purpose of this shell script is to record multiple AM frequencies from a single RTL-SDR and creates individual audio files per conversation.
|
|
|
|
## Requirements
|
|
|
|
Tested on a Linux box.
|
|
|
|
* [csdr](https://github.com/ha7ilm/csdr)
|
|
* [sox](http://sox.sourceforge.net/)
|
|
|
|
## Configurations
|
|
|
|
### Within the script itself
|
|
|
|
Change the values to your needs. Make sure the `centered_freq` and `sampling_rate` covers the `freqs`.
|
|
|
|
Note the syntax for `freqs` and `filenames`, they are arrays.
|
|
|
|
Each filename template use sox multiple output mode syntax for file numbering (`%6n`). The static part is reused by `dirWatch` to distinguish which `talkgroup` to import to.
|
|
|
|
```bash
|
|
audio_dir=./audio_files/air
|
|
device_id=00000001
|
|
center_freq=119.4e6
|
|
gain=38.6
|
|
sampling_rate=2400000
|
|
squelch=2e-4
|
|
|
|
freqs=(118.9e6 119.1e6 119.9e6)
|
|
|
|
filenames=(118900000-%6n 119100000-%6n 119900000-%6n)
|
|
