Low signal, probably. Do you have a signal amplifier connected to your TV tuner?

Saentist commented 9 months ago

I have direct vision to Tower ~25km and nice Fresnel, just tuner and 10cm antenna, not sure is LNA activated when scanning. All services are watchable no signal artifacts Where signal can be seen in log?

See log with "-vv"

stefantalpalaru commented 9 months ago

This is where it timeouts too soon:

        service = NovaNews (NOVA Broadcasting Group)
        Info: no data from NIT(other) after 13 seconds

Try increasing the timeout with -t2 or -t3.

Saentist commented 9 months ago

I read this as: "no other" frequency in NIT table to scan, also both frequency's have services founded. LOCK need to be enough for frequency to appear in generated frequency list.

stefantalpalaru commented 9 months ago

Try: w_scan2 -5 -t2

Saentist commented 9 months ago

I try, same result can attach log if needed

stefantalpalaru commented 9 months ago

Now try to also increase the filter timeout: w_scan2 -5 -t2 -F

Saentist commented 9 months ago

Don't see any difference in result but this generate and second frequency. Is there any explanation?

Very low SNR, as reported by "femon". I have much larger values:

SNR in FEMON is a old bug /or missing standard/ how driver report signal/quality in HEX /DEC/ 00-FF /or 0 to 255/ 000-FFF /0-4096/ 0000-FFFF /0-65536/ or mixed
