Siren 107.3   
This is a low powered community station at Lincoln. Would anyone within 30 
miles or so be so kind as to tune-in and tell me if they can receive it, how 
well they can receive it, and their approx location?

Using an old Sky dish for Freesat   
I recently moved into a new house where the previous residents had Sky, 
as well as Virgin cable.  As I understand it, the satellite system was 
working fine up until the day they moved out and they left the dish and 
the cabling.  I have never really been interested in what Sky offers, 
but I would be interested in getting a Freesat HD box to receive HD 
broadcasts from time to time.

 From what I have read, both satellites appear at the same position: 
28.2E so, assuming that the dish hasn't been disturbed in the wind or 
otherwise damaged by the recent weather, is it correct that all I need 
to do is plug the Freesat HD box into the satellite cable that comes 
into the house?

If so, any recommendations on the best box to get or the ones to avoid?
If not, what else do I need to do/get?

Freesat TV transmissions use exactly the same transponder streams as those 
used for Sky FTA channels, in other words a dish for Sky will work for 
Freesat, and the reverse, providing it has been aligned correctly. Freesat is 
really nothing more than an alternative EPG.

My parents have a 120 Quid Bush HD Freesat box, does the job, but the box does 
get very hot. Humax make one for 150 Quid. Before Christmas Humax are 
promising an HD Freesat PVR, they are showing it at next week's IBC trade show 
in Amsterdam.

The Humax one allows a second channel list with all the FTA non-Freesat 
channels, incl an HD one. Very good boxes I'm beginning to think, having 
sold a few.

If the sky dish was pointing at 28.2E just connect a Freesat box to the 
cable.

There are only two High Definition boxes with the Freesat branding
The Humax Foxsat and the Alba products

Alba = Bush, Goodmans and Grundig. Any HD box from the Alba brands will 
have identical electronics. The only difference will be badge/case and 
possibly the price.

Both boxes have had their problems but both are probable pretty stable 
now.  The Humax is still around £150 whereas the Alba boxes can be 
obtained for around £30 less.

The manuals for both boxes can be downloaded from the web

The Humax box does not run cool. After running for 2 hours parts of the 
case on my Foxsat have been measured at 57C   :(

They are the same signals from the same satellites, there are actually
four Astra satellites at 28.2E but your receiver sees them as one
system.The thing that makes Freesat Freesat, is the EPG which
to complicate things is broadcast from a fifth bird called Eurobird 1
at 28.5E but a small dish cannot even resolve this a separate bird.
I understand that some program streams also come from Eurobord 1

Eeek ! Still that MPEG4 decoder chip is doing one hell of a lot of number

see it at IBC next week.

Re: Using an old Sky dish for Freesat   
Yes, but I think unfortunately and unintentionally Graham may have
given the OP the mistaken impression that the Eurobird 1 signals
cannot be received at all, whereas he was really trying to say that
they can, because all the signals from different sats appear to the
dish as just as one big satellite.

To the OP:  Yes, basically you are correct.  The best way to test the
dish before splashing out is to try and borrow a receiver from family,
friends, or neighbours just to check that everything works as
expected, though there shouldn't normally be a problem.

We get quite a lot of enquiries like this here, so I've written a
document outlining the various options for receiving TV in the UK.  If
you have any further queries, that may help you answer them, if not,
come back to us here.

If Humax have done something similar on the PVR it may be the bottom of 
the case that is too hot to touch.

If the PVR is running hot it may be worth asking about the life 
expectancy of the hard disk or electrolytic capacitor at the elevated 
operating temperature.  A 12 moth warranty may only suggest a 13 month 
life expectancy :)

Buy the box, connect it up, switch it on,
and you are ready to go. Simple as that.
(other than tearing out the previous
connection to the phone line)

As part of the setup they ask you to input
your postcode. Should you want to watch
TV  from some other area than that in
which you are currently located, then just
input a postcode from the desired location

Incidentall whether it is worth spending
£150 odd on a HD rather than £50
at Argos for a SD is a moot point, IMHO

Thanks Mark.  I had a Humax Freeview box before getting the HD-Ready 
IDTV and was pretty pleased with it, although I wished at the time that 
I had waited for their PVR before buying.  That was just a spur of the 
moment thing while wandering round Sainsbury's and it was only later 
that I discovered it was a highly rated box.

I'll keep an eye on their web site and check when the HD Freesat PVR is 
released.

Well I would guess that the HD from the £50 SD box would be somewhat

What I would say is that SD [1] (via the Scart) from the Bush HD box is 
diabolical, the HDMI output for HD and SD channels is fine, so unless you 
intend to connect the box to an HD TV set via HDMI from day one, don't buy it.

[1] That's both native SD from SD channels, and downconverted SD from the HD 
channels.

Maybe a SD box but it will not be a Freesat HD box. More likely it will 
be a free to air box without the 7 day EPG.

I suspect they're reluctant to mention Sky in their blurb, for fear of making 
Joe Public think that Sky are in some way connected. You can't blame them, Sky 
have done a fantastic job of making a great many people think;

They cannot do that because some of their official partners only want to 
sell a box with installation even though a sky digital dish may be 
installed already.

Thanks for the info.  As the TV has integrated terrestrial DTV, I would 
only be looking at the STB for HD, via HDMI.  In fact, if possible, HDMI 
is the only connection I would want between the TV and STB.

Yes but you might as well have access to all the SD channels that are FTA on 
sat but are not on DTT. Several hundred on them if you get the Humax box.

Just connect via HDMI. That's all you need.

Undoubtedly. This so called "Accurate Recording" facility on DTT is worse
than PDC, which only failed occasionally for me.
AR misses the start of the majority of the things I record.

The whole DTT platform is a shambles though, what with the need of various
boxes to have to be rescanned when a new 'channel' appears and the
consequent loss all your timer settings.

Several hundred channels and nothing to watch.

There are several  hundred SD channels that can be whittled down to tens 
of channels assuming you don't want to watch the phone in sex, religious 
nutters and shopping channels :).

I believe the Alba boxes allow the addition of other free to air 
channels but via a manual mode on a channel by channel basis.

Some HD broadcasts have Dolby Digital 5.1 audio so maybe an optical link 
to an AV amp as well.

I recall there were some complaints about the HDMI interface between the 
Humax Foxsat and Panasonic (and other)  TVs resulting in 'soft' 
pictures.  This may have been resolved for some people when Humax 
provided a range of different output formats over HDMI thus allowing the 
receiving TV to operate in a different mode.

It may be worth searching  for 'Humax soft picture' in the digital spy 
(Freesat) forums.

The Humax box does get quite hot on the top surface. However if you are 
brave I suggest you run your fingers on the under surface of the box. Be 
prepared for some degree of pain! It appears to me that the heat sink for 
the main gubbins is actually the bottom plate of the box. It is a shame it 
is of pressed steel rather than say aluminium which would bleed off the heat 
more readily.

Having said that the box is hot and the underside is even hotter I do not 
think it really is anything to worry about, it does after all carry a 
sensible guarantee and if failure happens one can get one's money back and 
start over.
To avoid any potential problems I have placed my box on 35mm high legs ( 
black painted cotton reels) on an open shelf next to the TV. It now runs 
below egg frying temperatures.

The current issue of 'What Satellite' (September 2008) has an article
about whether it is possible to get the new Freesat service with a Sky
dish.  The answer should be blindingly obvious (i.e. yes), but the
writer found that he was given conflicting advice by, frankly, people
who should know better!

This may be so with a smallish satellite dish.  However, would that
necessarily still be the case for a much larger dish, as used in large
comunal systems?

OK, except they are all more expensive than Freesat HD receivers, though 
I do acknowledge they can record using external USB hard drives.

BTW, this one is only SD, don't be fooled by the HDMI interface :-

Without the EPG data, all are not terribly user friendly, and be aware 
that because ITV-HD has a rather eccentric set of parameters, (in 
attempt to make it only available to Freesat boxes) it might not be 
possible to view it on any of these boxes.

Now and Next is part of the DVB spec, so all receivers should support it.
However only having N&N available for a PVR would be a PITA, it's like going 
back to the VHS days as far as timer setting goes.

It is, but as it's only one of two FTA UK HD channels available, not receiving 
it for the sake of not buying a Freesat box would be cutting off your nose to 
spite your face.

Thanks Bill for your short, sweet answer!

I was wondering because I read somewhere that the larger the dish, the
more focussed it is and less likely to pick up stuff from the side.

It is possible if the dish is slightly misaligned it could still pick the 
sats at
28.5 OK, but too far off for those at 28.2, or visa versa.

True, but it needs to be a fairly large dish.

Astra D is transmitting around 11GHz +/-.

Schoolboy physics (remember when they taught that subject?):
Minimum angle, theta, that you can discriminate signals is 1.22 * c / (f 
* D) where D is diameter of aperture (ie. dish diameter).  In this case 
theta is 0.3deg, or 5.24mrad, c is 3x10^8, f is 11x10^9.

That works out to a dish diameter of around 6.5m, or 20ft - and that 
assumes a perfect dish profile, without tolerances.  ;-)
