Good evening, the scan stops abruptly with the above error and therefore impossible to obtain the list of stations. jj

I get the same on version 2.3 on archlinux.

Thanks for reporting.

1. Is it reproducible?
2. Can you try using rtl-tcp -> welle.io via rtl_tcp input?

[noone2k]

i'm in ... same problem ... using rtl_tcp works with a little delay ... and sometimes after the second try/channel change ... but once it works, it works ... btw. latest master-branch build , on arm64 ...

The signal level is probably too low. Needs >= 15 dB to get a sync AFAICS.

[andimik]

No, I don't think this issue is related to the reception.

[noone2k]

i rebuild the latest master as RELEASE, instead of DEBUG and its working. a little bit picky but it works ... the 2.2 is not so bitchy. and yes, where 2.2 lock a transponder/program faster with lower reception, 2.4 lock later and better with a higher snr. probably a little bit to few overhead with debug or something similar. i'm running welle-io-gui next to a fully blown gnome desktop on a "weak" sbc ( odroid n2+ )

[AlbrechtL]

Maybe you run into a unknown race condition because your are using a not really powerful CPU. When building as RELEASE the CPU load is roundabout 50% of the CPU load of DEBUG.
