Replying to myself is the first sign that I need to be committed to a mental institution. So here goes.

Thinking more about this, I don't think this is the case, if someone hasn't already corrected me -- there is a range of frequencies which, last time I scanned, were shared by both polarisations, with identical symbol rates. Although this was not legitimate input for an earlier `scan' and I've hacked a script to work around this. ### frequency pairs, h+v, mostly 27500 from 11200 upwards S 11222170 H 27500 S 11223670 V 27500 # S 11259670 V 27500 This has an odd SR NO MORE...

S 11344000 H 22000 S 11344500 H 27500 # S 11388830 H 27500 S 11390330 V 27500 This continues, more or less, through 11500. In other words, if your two low-band inputs to the multiswitch were reversed, you'd still get something on the above frequencies, even if the actual parameters you'd be reading wouldn't match what is actually transmitted. Sorry for the misleading info I posted earlier. If there is any cabling problem, I'm positive it would have been noted as the BBC channels are certain to be ones checked by any halfway competent technician. As far as the possibility that your tuner card isn't properly switching into low-band, if you were to modify your scan file so that the successfully-tuned frequencies above 11700 are repeated but with a value corresponding to the different IF frequency, and you can again receive the same services, then that would point to that problem. I'd give an example, but that would require me to think. But here's the idea -- if you've tuned 11720, that's with an IF of 10600. With an IF of 9750, you'd want to be tuning to 11720 - (10600-9750) MHz. If that makes any sense. thanks, barry bouwsma -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

On Wed, 4 Nov 2009, TD wrote: removed linux-dvb x-post Oooh, that's a mistake (from my view) -- it means your reply doesn't appear in my inbox, and it's only through luck that I find it amongst the uninteresting (to me) posts that I check infrequently on linux-media via gmane -- I thought there was to be a separation between developer mail, and dvb-user mail, and this clearly falls into the latter. And is more my bag. But that's a rant I don't want to get into, as I'm in the minority here. Therefore the failure to tune DVB-S2 transponders has nothing to do with reception of Freesat. I wasn't aware - I thought the Freesat HD channels were DVB-S2, that's why I got that card. Now upon further research, it appears that talk of DVB-S2 with Freesat has died down, so looks like I've wasted some money (for now). Happy to offer the background. I wouldn't say you've wasted money -- rather, you've future-proofed yourself. Sadly the Freesat specs don't appear to have mandated the more efficient H.264 AVC video codec for SD resolution services, so there is no possibility of that for a Freesat-only (no BSkyB) service that wants to save transmission costs, yet still be received by the handful of non-HD-able receivers out there. I'd liken it to my decision not to buy any DAB-only receiver without the DAB+ (and DMB) capability that is presently in use (if not in the UK or other countries), or any further DVB-S cards without -S2. And DVB-T2. What seems like a waste of money today will guarantee you don't have to spend as much later -- with your DVB-S2 card and a suitably positioned dish, you could be receiving the french-german `arte' where occasional programmes capture my interest, as well as other FTA services that have not yet interested me in a pure -S2 form. Also, while the Beeb may not presently be transmitting -S2 for their HD service, I wouldn't rule it out. There's a long and sordid history behind Freesat and the Continent that limits what is available via Freesat and its quality to what the 2D satellite can deliver, and any future services (such as the recent Freesat `Five') will need to be shoehorned into that already overfilled space. My channels.conf contains both horizontal and vertical channels, but nothing below 11700. So it looks like I'm not getting anything via low band? Thanks for confirming this. This points to a potential, but unlikely, problem with your device, that it can't switch into the low band (I had a problem where one of my devices could not receive anything in the high band without hackery, or a multiswitch which spoke to it differently). If you are not aware of it, in case it helps, the switching between low (below 11700-ish) and high band is normally accomplished with a 22kHz tone signal, absent for low band. It can also be accomplished by a particular DiSEqC signal which my one device speaks to the multiswitch I got which solved that problem, that being the opposite to what you are experiencing. The other possibility, given that two of the four inputs to your multiswitch work, is that the two low-band inputs have been crossed. If you have a complete lack of any results with one particular polarisation/band combination, then suspect possibly your cabling, unless a regular FTA/Freesat/Sky receiver connected to the same is able to successfully find all services. As per my OP: = The setup is that this is a newly-built flat, with a double F-socket on the = wall. I followed it down to the distribution panel in the basement, and it's = connected to a Delta MS 5024 N multiswitch. From what I could make out, said = switch has four cables going in (vertical 0khz, horiz 0khz, vertical 22khz, = horiz 0khz), and lots of cables going to the flats. Surely it must be the switch, I don't see what else it can be, especially if there is no special signal that a Sky box sends down the wire to the switch, that my setup would need to replicate. Yeah, a third possibility could be the switch. I glossed over the details in your original post about the switch, and completely forgot it was newly-built. While I would normally expect everything to work in a new installation, I've read enough to convince me otherwise. As a confession, when I have to replace the cabling into my multiswitch, these days I determine the proper wiring by a process of elimination as to which of the four cables goes where. I recently had to do this with my dish pointed at 28,2/28,5°E and I'm always wary when I have the mathematically improbable result of the randomly selected cables being connected to the right inputs. But enough of my confessions why you wouldn't hire me to install anything you care about. There is a caveat above, which is that we are the first people in the block, so who knows what reception others are getting. I've already had the cables from the switch to our flat moved to a different switch, as when I mentioned Different switch, or different

There are currently no DVB-S2 transponders carrying any FTA services, although there is always the possibility that the existing FTA HD services which are on DVB-S transponders may move to DVB-S2 in the not- too-distant future, particularly when the terrestrial UK DVB-T2 services start before the end of the year, and Channel 4 and Five join the existing ITV and BBC HD services. Therefore the failure to tune DVB-S2 transponders has nothing to do with reception of Freesat. Enough background, what I see from the above is that the frequency of 11720 has a symbol rate of 29500 which I know is what is used by the BSkyB encrypted programmes. So your ability to tune isn't going to help you see any additional services, just as those in your original post are also scrambled Sky programmes. If it concerns you that you can't tune this DVB-S2 transponder, then you'll need the advice of others with DVB-S2 familiarity. and the channels.conf was no better than before - it didn't include *one* BBC channel, for example. The BBC channels, as well as most ITV, Channel 4, and similar ``interesting'' Freesat services, are on the Astra 2D satellite, as per your subject. This bird covers the frequencies from 10714250 h 22000 through 10935500 v 22000. Its footprint is a narrow beam focussed on the UK, and can only be received with some difficulty elsewhere that the remaining signals from the other Astra and Eurobird satellites deliver useable signals. That is, were you to be somewhere outside the UK, you might need to more accurately position your dish. But that shouldn't be your problem as per your original message. Once I got it working, same: Astra 2A/2B/2D/Eurobird 1 (28.2E) 10714 H DVB-S QPSK 22000 5/6 ONID:0 TID:0 AGC:0% SNR:0% Can't tune Where do I go from here? I note that your first listed frequency is 11720, just above the transition from low to high band, in your first message. Do you get any results with success at any frequencies below 11700, and do your successes above 11700 include both horizontal and vertically polarised services? If you have a complete lack of any results with one particular polarisation/band combination, then suspect possibly your cabling, unless a regular FTA/Freesat/Sky receiver connected to the same is able to successfully find all services. You should be able to receive services from 11200 to 11700 in both bands with DVB-S, as well as above 11700, as the former are not on a particular spotbeam. Hope this info helps. Feel free to send me off-list your `scan' output (DVB-S) if you can't spot any patterns. thanks, barry bouwsma -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
