drops #97

Closed hemna closed 4 years ago

hemna commented 4 years ago

Hey guys, I've had goestools running for a long while on my rpi in a docker container. I've been noticing that I've not been able to decode any packets for a while due to drops. I'm seeing vit rates between 280 and 500, all with 13+ or so drops. I'm not sure what's up. Am I just not getting good enough signal to decode anything?

It's likely that your machine is dropping I/Q samples before they're reaching goesrecv. If you're using a Raspberry Pi, then it might have its CPU throttled. This can happen because of high temperature or high load and can be undone by rebooting it.

It was due to a bad power supply, causing low voltage
