UEO - Unidentified Error Object #22

Closed brendanvg closed 8 years ago

brendanvg commented 9 years ago

It seems to be recording but there is an error message I can't figure out and when i check the recorded files they are empty... I didn't do anything to setup my R820T dongle and antenna, just plugged it in...

I've gotten the trunk-recorder configured thusly:

how should i go about debugging this?? Thanks robotastic!

robotastic commented 9 years ago

Hmm... good question. I am not sure if anything is necessarily wrong. Are you sure you have the error correction set? Try giving it a negative value instead or vis-versa. I will try it with my RTLSDR this weekend, I haven't done that in a while.

brendanvg commented 9 years ago

something seems to be wrong because nothing is recorded to the audio files outputted and (as per my more recent issue) the void handle_message function never gets executed.... I'm not sure why this function wouldn't be getting called, but I;ll look into it... also, the next thing I'm going to do is try to set the hardware gain because in gqrx when the hardware gain control is not set to automatic the signal is much weaker.....(and perhaps i'm not getting enough message packets....)

robotastic commented 9 years ago

Yep! Definitely set the gain. Try something high like 60 in the config file and then walk it down. Take the gain off auto in GQRX and look at what value works well there. it should be the same.

Closing since there has been no update and the code has been updated to fix a lot of problems.
