I made up that frequency, in case it wasn't obvious. The closest is 12342 H 27500 3/4 which offers some RTLs and BBC Prime. Sadly BBC Prime is scrambled for some sort of satellite operator...
<frequency> <polarisation> <symbol rate> <FEC>for example:
BBC World - 12285 V 27500 3/4
The frequency is specified as five digits with no decimal point, your Digibox
will place a decimal point between digits two and three, such as
The symbol rate, also, is given as five digits with no decimal point. The possible rates are 22000 and 27500 while the Digibox says 22 and 27.5. The Digibox measures in Megasymbols/sec while I use kilosymbols/sec. Same thing though...
This is not actually strictly true. Some channels have an offset larger than 19, I suspect these offsets are between satellites. It helps to have my list handy so if you spot that the channel you calculate (with your handy calculator) is a few digits off, you can correct it.
The process is a bit weird. Here goes. You'll see a reasonable signal quality
and lock will say 'OK'. This is because, when you aren't doing anything else,
the Digibox returns to the default transponder (perhaps this is where it gets
the menu music from?).
Upon finding digital channels, the Network ID and Transport Stream will both become 0000 for a moment, to be updated by the new values. Press 'Select' and you can pick from the channels shown.
As a rule of thumb, the frequency range is 10700 to 12750. The channels in the middle (say, 11500 to 12500-ish) use 27500 3/4 while the remaining channels (on the 'outsides' of the frequency range) use 22000 5/6.
Note that the Digibox supports a number of FECs, but it only supports the two symbol rates already discussed. If you have a little broadcaster that uses, for example, 11000 or the like, you will not be able to receive it with a Digibox. The majority of other digital receivers support 1000 to 45000 (give or take a little - the 100 euro box goes up to 30000kS/sec, and amusingly the 1,300 euro box only goes up to 32000kS/sec!).
"Infocast mail Astra" 11511 V 22000 5/6 "Test_R" 11834 H 27500 3/4 "Astra Satmode" (many) 12245 V 27500 3/4
Also, keep an eye on the following combinations. They appear to be valid digital transmissions but report 'No channels found' (not even test channels).
11473 V 22000 5/6 11872 H 27500 3/4 11910 H 27500 3/4 11967 V 27500 3/4 12435 V 27500 3/4 12727 H 22000 5/6
If you are 'into' signal extractions (you know what I mean), then you may
like to take a look at "BBC Prime" which is an evening-only channel
broadcasting the 'best' of BBC things. Whether or not it is 'the best' will
depend a lot on your tastes. You can find this at 12340 H 27500 3/4
and again at 12378 H 27500 3/4.
You will also find a large number of themed radio stations (i.e. Traditional Country, New Country, UK Hits, Italian Contemporary, '80s Hits) at 12043 V 27500 3/4. If you find out how to receive these, please let me know! An '80s only radio station sounds right up my street.
To remove a channel from the Other Channels list, highlight the channel and press yellow
but WARNING: You aren't asked to confirm, it happens immediately.
When you next select a valid channel there will be a pause of a second or so as the channel list inside the Digibox is updated.
Note also that the cursor moves up the list as you delete, so if deleting more than one channel at a time, be careful that you don't nuke channels you want. This has caught me out a few times...
You'll find a simple colour-bars testcard at 11568 V 22000 5/6.
And Happy Hunting!
