Good evening friends how are you
I have a problem with the new zgemma h5 AC atsc
When I want to scan a cable tp, he signals me but does not bring any channel does not scan anything
I have a cable operator in South America working with annex b
For example its frequency is 447 sr 5057 qam 64
What I see is that the menu in the zgemma does not give me the option to load the SR
FROM ALREADY THANK YOU VERY MUCH

We had several reports from American users from Terrestrial part of ATSC.
You are the first reporter for Cable part of ATSC.
The Symbol Rate is not included in the current implementation. Changes should be made to support symbol rate.
In the meanwhile, there is a command line utility in the feeds, wscan (or w_scan).
You can give a try with that utility and chech if it scans correctly?

You need to use telnet commands.
# install
opkg update opkg install wscan# scan
w_scan -f a -A 2Use w_scan -H to get more help.

Good morning, How are you? Athoik.
Yesterday probe with the wscan and also gave signal but did not scan anything
What I see in the wscan are not thistles for example SR 5057, 5360
I do not think it has anything to do but I noticed it ajajja
I attach the photos
From already thank you very much

It works for ATSC/Terrestrial as far as i know.
Can you try again using the following command?
w_scan -fa -A2 -c US -X

For sure Enigma2 misses the Symbol Rate for ATSC ANNEX-B although during the tests with hardcoded "Symbol Rate" nothing good come up!?
diff --git a/lib/dvb/frontend.cpp b/lib/dvb/frontend.cpp index 561fb81..f11b86c 100644 --- a/lib/dvb/frontend.cpp +++ b/lib/dvb/frontend.cpp @@ -2217,6 +2217,16 @@ void eDVBFrontend::setFrontend(bool recvEvents) case eDVBFrontendParametersATSC::Modulation_VSB_16: p[cmdseq.num].u.data = VSB_16; break; } cmdseq.num++; + + if (parm.system == eDVBFrontendParametersATSC::System_DVB_C_ANNEX_B) + { + int tmp_sr = 5604; + CFile::parseInt(&tmp_sr, "/tmp/symbol_rate"); + + p[cmdseq.num].cmd = DTV_SYMBOL_RATE; + p[cmdseq.num].u.data = tmp_sr * 1000; /* parm.symbol_rate; */ + cmdseq.num++; + } } p[cmdseq.num].cmd = DTV_TUNE, cmdseq.num++; if (ioctl(m_fd, FE_SET_PROPERTY, &cmdseq) == -1)The default value is 5604 (i seen that number several times in above picture).
In order to change to 5360 do the following:
echo 5360 > /tmp/symbol_rateSo it might be a driver issue, although strange that w_scan find something.

Posting the same question multiple times doesn't get you an answer quicker. So please don't.
Also, don't hijack other topics, create your own if you have a new question to ask.
Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), uClan Usytm 4K Ultimate (S2+T2), Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)
Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.
