Frequently Asked Questions

• Some of the recordings has a file size of 44 bytes, what gives? That generally means that the digital recorder was unable to decode any audio. Why that is happening is a tough question. It could be that the source isn't tuned correctly. Try adjusting the amount of error and gain. If you are using a FSK, try adjusting fskGain in the config for that source. Try "0.80" or "1.20" to see if that helps.

• I am using 5 RTL dongles and I am getting the following error:

Failed to submit transfer 3!
rtlsdr_read_async returned with -5

This appears to be something weird with the osmosdr driver. Try decreasing the buffer size for each dongle in the source config. I have found the following to work: "device": "rtl=31,buflen=65536” where 31 is the serial number for the dongle and 65536 is the shorter buffer length. Make sure there is a comma, but no space in between the parameters.

• The priority settings don't impact recording

Set the priority for things you don't want to record to 999 in the talkgroup file
