Hello James ,Interesting Joachim, I used to have a 1.8m dish for Meteosat WEFAX and PDUS at much lower ERP and don't remember so many problems in that was it S-band? So the increase to Ku I suppose is the downlink issue. OT but BTW I had a fascinating fsy experience yesterday (and today) - the wife power-washed the patio and frequently stood in front of the dish. For the first time I saw DECREASES in the 0.fsy which wasn't my intervention. http://www.meteosat.co.uk/mrtg/satellite-fsy.html (It's the 18:30 & 13:15 dip approx) Cheers James -- James Brown

Interesting Arne,

I had thought that a big dish might have been able to punch through, but perhaps with a very narrow beam the losses in heavy precipitation become too great with the amount of data. I have a feeling John Tellick may be along shortly with the statistics! Now a RAID system would be 'interesting' if a little impractical possibly!

Hello James ,

sometimes i have the same problem with the loss of the satellite signal. Specially if there are heavy rainshowers during thunderstorms. I am in the northern part of Germany and i am using a dish with 1,5m diameter , but during heavy rain the signal to the satellite brakes also down. Greetings Joachim Empel ( DL2388RB )

The rain attenuation on Ku band can be so high that upping the power may only shorten the loss of signal a bit. That is why they still use 4 GHz in regions where "tropic downpours" occur frequently. A second up-link station on a different location could help if running synchronized "in parallel". Let us hope that these severe rain showers will be rare. Eastern Europe (Poland especially) has had enough rain for a year now !

Re: recv-channel.ini" setup
Hi This is going to be a long one so get a cup of tea,I have just had to reinstall all software from scratch as David will know all about. I have everything running including ramdisk and all seems well but i need to overwrite the recv-channel.ini" file to put in only the data i need to recieve. I cant remember how to go about this as it has been 3 years since i needed to touch it . I dont know what to edit ect . i am at this moment recieving msg data also avhrr and metop only. I could do with a screen shot or some help if you would . i apreciate all your advice Thanks Duncan..Duncan, There are some hints here: http://www.satsignal.eu/software/msg_dm_pc.htm#FileLocations Cheers, David -- SatSignal software - quality software written to your requirements Web: http://www.satsignal.eu Email: david-taylor@blueyonder.co.uk

Hello,
On the back cover of the new GEO magazine (26) displays an image from the SPOT-4 satelite. Is it possible for weatheramateurs to recieve this kind of pictures? regards Geert www.hetweerinboskamp.nl

Thanks Douglas, I guess that is more or less a confirmation then. I monitor the earthquakes most days - the whole area seems susceptible to tremors of a 1-2 on their scale. I'll see if I have any saved images from before to compare. Cheers James -- James Brown

MODIS Iceland image query
James Brown
It's good to see the MODIS images coming in again.
I was looking at the latest one covering Iceland (very clear) and it reminded me that for some times I have seen large areas appearing much darker than the surroundings. I was just wondering if this could still relate to a covering of ash from the volcanic eruption? I wonder what others think - the wind direction did at times carry the cloud further east and north. Cheers James -- James Brown

I see there has been some data loss at approx. 9.10 / 9.15 UTC with lossesSame here, Ian. No missed packets, though, so something higher up the chain. No notice of any work today, I believe.

Re: Missing MODIS
James and others I note the following information from NOAA which mayI saw that note, Douglas, but didn't connect it. Mind you, to me ESPC is the Edinburgh Solicitors Property Centre! Quite a time for a server to be out.... Seems we had our own incident around 16:00 with, I suspect, bad weather over Usingen causing a Europe-wide outage. I managed to get Windows updates done on my main PC just before the signal came back.
