[07:41] <mrkiko> Hello guys
[07:42] <mrkiko> With my DVB-T device, based on xCEIVE 3028 + dibcom 700 (model name: ASUS My Cinema Hybrid U300), I can receive in a good way relevant channels here, except the Italian national one, RAI; RAI transmits un VHF and UHF. Can you give me some hints about this?
[07:45] <mrkiko> w_scan crosses the frequency where those channels are in here, 177.500, but without seeing them
[07:45] <mrkiko> and also trying to specify their parameters didn't solve the issue
[07:52] <_BradC> Where (or to whom) would I submit an updated DVB-t scan list for Perth, Western Australia and what is the preferred format these days?
[07:56] <mrkiko> _BradC: an unrelated question, what hardware do you use?
[07:57] <_BradC> I am using a couple of : Realtek Semiconductor Corp. RTL2838 DVB-T USB devices on a Raspberry Pi 3 at the moment.
[08:00] <mrkiko> _BradC: I am searching for a well supported / functional hardware
[08:01] <mrkiko> _BradC: why more than one dongle?
[08:02] <_BradC> mrkiko, these were $15.50 for two, landed from China. They worked out of the box with absolutely zero hassle. I grabbed the RTL2838 from a recommend device list somewhere, bunged it into E-bay and bought the cheapest ones that came along. 10 years ago I spent too much money on DVB-S hardware and had nightmares with it, so I wanted a cheap start to see if it was a viable option.
[08:03] <_BradC> mrkiko, I have 2 dongles so I can record and make sure my wife can still watch her shows. We have 6 frequencies, and the chances of me wanting to be recording one while she watches another are pretty high.
[08:05] <mrkiko> _BradC: thank you for the hints. I had an RTL hardware, but don't remember the exact number, it was also rtl-sdr supported hardware. the problem was receiving the signal, no signal here
[08:06] <mrkiko> With that device... now I am trying to use, as I wrote, a dibcom + xceive device, which works fine, but I am trying to understand why I can't see my national channels (RAI) ... I am new to dvb-t
[08:06] <_BradC> mrkiko, I have a *big* antenna and lots of RG6 because I've had some pretty insensitive tuners over the years. These things work fine.
[08:07] <_BradC> Having said that, I had to do some searching because the dvb-t scan lists are a couple of years out of date here and I couldn't find half the channels out of the box. We had a channel re-allocation about 2 years ago.
[08:08] <mrkiko> _BradC: did oyu use w_scan at the end?
[08:08] <mrkiko> _BradC: I don't know if I am in your same situation... what steps might I take? I tried various w_scan usage mode
[08:09] <miasma> hm, any suggestions as dvb-c receivers? i bought the astrometa usb dongle, but it only works as a dvb-t tuner http://blog.palosaari.fi/2014/09/naked-hardware-18-astrometa-amdvb-t2-v2.html
[08:09] <mrkiko> miasma: sorry, no dvb-c here; does it work well as dvb-t? 
[08:09] <_BradC> mrkiko, No, actually I found a frequency list somewhere and changed the frequencies to suit. I actually started using tvheadend, so I could edit the data in the web interface. Once I had that working I copied manually into a scan file and verified it with dvbv5-scan.
[08:10] <miasma> mrkiko: i only have the small antenna that came with the device and it can't find anything. it works for sdr though
[08:11] <mrkiko> miasma: oh, I was in that situation, not pleasant I think... can't help, sorry
[08:11] <miasma> apparently all those cheap chinese dongles come with a small antenna like this http://img.dxcdn.com/productimages/sku_283237_6.jpg
[08:12] <_BradC> miasma, mine came with those. I gave it to my 2 year old to play with and plugged the dongle into a real antenna.
[08:12] <mrkiko> _BradC: so it can happen that w-scan doesn't think channels that are there. I am a blind user and currently not using GUI apps. So you suggest me to try to find some info about the channels I can't see and try to import them in a initial data list?
[08:12] <miasma> mrkiko: no problem. i might need to buy some dongle from a better brand. i couldn't really figure out why the dvb-c frontend dev file didn't show up. all the drivers seem to load
[08:13] <mrkiko> _BradC: you did do so because the dongle supported it, mine had an integrated antenna if I am not wrong
[08:13] <_BradC> mrkiko, I've not head of w-scan. I'll go and have a look.
[08:14] <mrkiko> miasma: good luck 
[08:17] <_BradC> mrkiko, Huh, so w-scan is available in Debian. I've installed it and as soon as the program I'm currently recording has finished I'll fire it up and see what it does with these dongles.
[08:21] <mrkiko> :D that's fine
[08:21] <mrkiko> I am now trying to understand how to scan for muxes
[08:37] <_BradC> mrkiko, I started it with w_scan -c AU -x (Australia and generate initial tuning data) and it shot off testing every viable frequency in sequence looking for muxs. In about 3 minutes it had identified all available frequencies here and then started to run up the rest of the band looking for anything else it could find. Once it finished that, it went back and hit each detected Mux for a list of channels. Total scan time about 10 min
[08:37] <_BradC> utes. It got all the available frequencies and channels.
[10:56] <mrkiko> sorry, reading now
[10:57] <mrkiko> _BradC: so w_scan rocks ? :D
[10:58] <mrkiko> I was able to find some channels I where searching for by increasint the timeout a lot
[11:04] <mrkiko> no good sign when you receive messages like: dvb_read_sections: no data read on section filter
[13:11] *** debianuser has quit IRC (Remote host closed the connection)
[14:36] <mrkiko> ok guys
[14:36] <mrkiko> problem detected
[14:36] <mrkiko> once I receive an higher frequency channel, low vhf channels stop working
[14:36] <mrkiko> seems a firmware bug for which windows drivers does have a workaround
[14:54] <merbanan> miasma: dvb-c works fine with the astrometa device
[15:17] *** XSoul has quit IRC (Ping timeout: 244 seconds)
[15:27] <miasma> merbanan: my problem is, i only get /dev/dvb?/frontend0, no frontend1
[15:28] <miasma> merbanan: I'm waiting for my distro kernel, maybe they do it better than me with my own kernel. after all, the astrometa device I have got out of staging in kernel 4.8
[15:29] <merbanan> miasma: you might need to install newer drivers
[15:35] <miasma> merbanan: what newer drivers?
[15:35] <miasma> you mean a kernel that's not yet even released is too old?
[15:44] <merbanan> no just the linuxtv out of kernel drivers
[15:44] <merbanan> I run that and dvb-c works for me
[16:09] <miasma> i could try looking for new firmware
[16:09] <miasma> i'll report back once the 4.8 is stable and arch linux packages it. we'll see if it autodetects the dvb-c part of the dongle then.
[16:11] <miasma> basically sdr works, dvb-t part works (if I just had big enough antenna) and all software detects it as a dvb-t dongle, but the dvb-c part is missing. I installed firmware, tried kernel 4.7 and 4.8. no hope. apparently there's some issue with the external tuner
[17:17] <mrkiko> sorry, exiting
[17:17] <mrkiko> thank you guys forall, sorry if I lost messages
[17:17] <mrkiko> thanks
