When scanning for DVB-C channels in Helsinki region using the scan data Kaffeine automatically downloads, at least the channels SubTV, Nelonen and JIM are missing. The three channels were scanned correctly after I added the following line to [dvb-c/fi-HTV] section of .kde/share/apps/kaffeine/scanfile.dvb: C 282000000 6900000 NONE QAM128 Reproducible: Always Steps to Reproduce: 1. Download the initial tuning data using Television / Configure Television / Update scan data over internet 2. Start channel scan 3. Try to find SubTV Actual Results: Scan finds many channels but not SubTV, Nelonen or JIM Expected Results: Scan finds many channels including SubTV, Nelonen or JIM The three channels were scanned correctly after I added the following line to [dvb-c/fi-HTV] section of .kde/share/apps/kaffeine/scanfile.dvb: C 282000000 6900000 NONE QAM128
Use this http://www.linuxtv.org/wiki/index.php/Dvbv5-scan to scan your channels and then send the results to linux-media@vger.kernel.org Let me know when this is done and Kaffeine source will be updated. Manual: http://git.linuxtv.org/cgit.cgi/dtv-scan-tables.git/about/
Tried with dvbv5-scan from ubuntu package v4l-utils and initial tune data from dtv-scan-tables, got this: ojs@eris:/tmp/dtv-scan-tables$ dvbv5-scan dvb-c/fi-HTV INFO Scanning frequency #1 274000000 Lock (0x1f) Signal= 53.73% C/N= 96.47% UCB= 63222 postBER= 1658880 Segmentation fault (core dumped) I tried to build dvbv5-scan myself but got this: ojs@eris:~/prog/v4l-utils$ ./bootstrap.sh autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal --force -I m4 autoreconf: configure.ac: tracing autoreconf: configure.ac: AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION autoreconf: configure.ac: not using Libtool autoreconf: running: /usr/bin/autoconf --force configure.ac:76: error: possibly undefined macro: AC_PROG_LIBTOOL If this token and others are legitimate, please use m4_pattern_allow.

The current scan file still gets at least one line wrong: C 290000000 6900000 NONE QAM256 finds the bundle that contains Yle HD channels. The file comes with QAM128.
I managed to get channel scanning to work with Arch. Here are the results from wscan -fc -c FI -x. I tested that this initial scan list finds all channels in Welho network (the identifier "fi-htv" is obsolete as well) C 146000000 6900000 NONE QAM256 C 378000000 6900000 NONE QAM256 C 386000000 6900000 NONE QAM256 C 394000000 6900000 NONE QAM256 C 178000000 6900000 NONE QAM256 C 186000000 6900000 NONE QAM256 C 194000000 6900000 NONE QAM256 C 202000000 6900000 NONE QAM256 C 210000000 6900000 NONE QAM256 C 218000000 6900000 NONE QAM256 C 226000000 6900000 NONE QAM256 C 242000000 6900000 NONE QAM256 C 258000000 6900000 NONE QAM256 C 266000000 6900000 NONE QAM256 C 162000000 6900000 NONE QAM256 C 154000000 6900000 NONE QAM256 C 170000000 6900000 NONE QAM256 C 274000000 6900000 NONE QAM128 C 250000000 6900000 NONE QAM256 C 290000000 6900000 NONE QAM256 C 298000000 6900000 NONE QAM256 C 306000000 6900000 NONE QAM256 C 314000000 6900000 NONE QAM256 C 322000000 6900000 NONE QAM256 C 338000000 6900000 NONE QAM256 C 346000000 6900000 NONE QAM256 C 354000000 6900000 NONE QAM256 C 362000000 6900000 NONE QAM256 C 370000000 6900000 NONE QAM256
The long term solution is to let the good people at linuxtv know about the frequencies.
I did before posting the scan results above. No response so far, and the downloaded scanfile is still wrong.
There is a commit for dtv-scan-tables tree updating the dvb-c/fi-HTV file. commit 9d6094a7c41e1ad11b90e719be12592222d57f90 Author: Ville Skyttä <ville.skytta@iki.fi> Date: Wed Jan 6 15:47:35 2016 +0200 dvb-c/fi-HTV: Update from http://dvb.welho.fi/hel5-sidump1.xml On a quick look, it seems that it has already the channels you scanned. Anyway, if something is still missed, please send the dtv-scan-tables update to linux-media@vger.kernel.org.
