European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) announced changes in the broadcasting and satellite positions used for data transmission in Europe. Service EUMETCast Europe will be from August 2014 broadcast from Eutelsat 10A (10 ° E) in DVB-S2. Broadcast on satellite Eutelsat 9A (9 ° E) in DVB-S will be completed in December 2014. EUMETCast the service transmission and distribution of meteorological data obtained primarily from the satellite technology in DVB-IP (Multicast). Part of the data is available free of charge, but requires software to read data, while others require the purchase of hardware key to decrypt the information (40 euros). Software license TELLICAST from Newtec costs from € 60, depending on the version. EUMETCast used in Europe transponder on Eutelsat 9A (9 ° E) operated by Media Broadcast (TP 63, freq 11.977 GHz, pol H SR 27500, FEC 3 / 4, DVB-S/QPSK). Uses are 20.5 Mbit / s bandwidth and gradually approaching its limit (amount of capacity used by service Akubis Direct issuing every Tuesday at 13:00 Conax encrypted system for broadcast dealer Mecedes-Benz). Given the interest transmit more data, EUMETSAT has decided to move the service EUMETCast Europe in DVB-S2 satellite to the new position, he will have even more capacity. EUMETSAT has announced that after a period of six months from August 2014 the service will be broadcast simultaneously in DVB-S2 Eutelsat 10A (10 ° E) and DVB-S from Eutelsat 9A (9 ° E). After the concurrence of the existing distribution terminated (it is not known what will happen to the service Akubis Direct). Interestingly, the 10 ° E, the operator will use DVB-S2 using technology VCM (Variable Coding and Modulation). It requires the purchase of a suitable DVB card that supports this type of transmission (there are not many on the market and in particular the products based demodulator STV0900 or STV0910 STMicroelextronics). The products are more expensive than standard DVB cards that can still be used. With technology VCM EUMETCast will be possible to transmit two different transmissions from one frequency. The basic service will be broadcast in 8PSK modulation and FEC 3/5 and makes it easier to receive a parabolic small dimensions. Extended service will use 16APSK modulation and FEC 2/3. It offers higher throughput (transfer operator expects about 1.5 times more data) and the reception will be necessary to have a larger antenna. Distribution of position 10 ° E will be the technical tests are already engaged in July 2014 and in August will be offered to all participants. On Dec. 31, 2014 broadcasts will end at 9 ° E. The planned technical parameters EUMETCast from August 2014: Satellite: Eutelsat 10A (10 ° E) Frequency: 11.325 GHz Polarisation: Horizontal SR: 33000 ksymb / s Roll-off: 5% Standard: DVB-S2 Modulation 1 (basic service): 8PSK, 3/5, MPE transport stream ISI = 1 Modulation 2 (optional service): 16APSK, 2/3, MPE transport stream ISI = 1 Note: New parameters can still undergo minor changes after a phase of technical tests in July 2014. Appliances that meet the requirements for receiving EUMETCast from August 2014 (tested and marked with the operator): - Ayecka SR1 (price around 300 to 410 euros) - Newtec EL940 IP (price around 3,500 euros) - Novra S300N (price around 300-435 euros) Requirements for receiving EUMETCast since August 2014: - support DVB-S2 - support for the symbol rate to 33 Msymb / s - Support QPSK, 8PSK and 16APSK, including all FEC values for the modulation - Support for VCM, Multiple Transport Streams (MIS), MPE - support at least 4 PID values for basic service and 4 PIDs for extended service - users may be able to assembly / installation / configuration of additional network adapter when the system is used by the router LAN DVB - necessary support IP data transmission at 50 Mbit / s for basic services and 80 Mbit / s for extended services used

I wonder if Timo has seen the snow shield over that LNB in the second picture down the page of the above web page!

Yes! I've been tempted to try one but was worried they looked a bit too flimsy for the dish I had in mind if the snow was to build up over long unattended periods.

Your "bottle"type must be quite rigid really, bet it would take some weight before it distorted.

Yeah except I think it needs those thin 23mm feed horns to work well. The dish in Lapland has a big Black Ultra on it. I'm going to try one of the LNB covers from one of the site sponsers first to keep light snow off (larger amounts can be manually knocked off without fear of crushing anything).

It'll be interesting to see how good they are, those from RED APPLE keep the rain of the face of the black ultra so thats something.

Perhaps when the freeze up starts you could clean the snow and summer muck off whatever you get.

Then rub on some -65C car screen wash concentrate which you can get anywhere there, you can get it in Halfords here. That sticks quite well to the car windows so it should stick well to plastic. Ice will not form on it. Snow will slide off easily. You would have to renew it from time to time but I can't think of anything else that would work there with the overnight low temperatures.

The LNB shield shown on that website and for sale here was iirc designed in Norway.

That website is one of best I've found for local sat stuff in Finland if you can live with the prices...

The dishes in question are left to fend for themselves for most of the winter where it can get up to a metre of natural snow, it's just me that uses them mainly for a few weeks a year. Thanks for the windscreen wash tip, might try that on some dishes in Helsinki.
