I have never lost segments this way. I switch to Status frequently to watch signal level and also had it opened for at least a week during the solar outages. But Ian is correct in leaving the receive PC alone, because I did loose lots of segments just opening Explorer on the received folder ! Running only a Celeron 800 Mhz with 256 Mb ram this is something I can live with. Apart from a failing harddisc two weeks ago, this PC has been powered on from May and is only rebooted for updates or at power losses. Did improve on cooling a bit by adding a case fan and removed the slotcoverplate below the old version Skystar. I do run a "lean" W2K Pro SP3, have not applied any security patch and had to disable the scardsvr process before I upgraded to TQ231. Have no firewall, virus scanner, time sync or defrag running on this PC and did set powermanagement to "full on". David try to borrow/get a satsignal meter to check if you do not suffer from fast signal fluctuations at windy conditions. Or borrow an old analog sat receiver with a signal meter output. This could convince the installer to check the alignment and fixing of your dish. Greetings, Arne van Belle

I had a problem getting my dish aligned; I'm in N Ireland so I've probably got a similar signal to you. Rather than bring in the "professionals" consider investing in Timestep's simple alignment meter. (If I remember correctly about £20-£25.) Assuming you can access your dish, simple hand pressure on the horizontal and vertical axes will allow to get the alignment spot on. Here, it's blowing a real gale at present and while my dish is at the bottom of the mast I use for my QFH and sways a bit, signal strength (normally 70%) is dropping to 59%, SNR drops from 10.9 to 9.2, but the BER is unchanged at zero.

If I want to have a look at signal level I do it after I have shutdown Tellique. The only other issue (don't know whether it is relevant or not) is that I have the original Tellique software (pre MSG). I do hope you will get this resolved.

Re: Missing segments
Just one other thing as a long shot. I once tried whilst MSG datawas coming in, looking at the signal level on SetUP4PC....disaster. You must not do anything with that program during MSG reception or data can be lost.... not even checking signal level. Douglas, Thanks for your comments on dish alignment etc. I'm phsching myself up to calling the professionals again! (They did seem to take good care when installing, that's why I'm reluctant). I run Setup4PC all the time when receiving MSG-1 and have not, as far as I know, ever had a problem due to this. I have the Statistics screen on permanent display. What you say surprises me. Has anyone else found this? Cheers, David

Re: Missing segments
John Parkins <kvp@...>
Hello David,
I use a 1m dish here in London and get 80%+ and a SNR of 12+. I would have thought that so long as your getting a fairly solid signal this wouldn't be causing lost segments. I have to say though that apart from the ones reported by others I don't seem to miss any, the dish does have the mother of a bracket on it though and doesn't move a bit even in the highest winds.

Hello All,
Came home this afternoon to a strange email from Eumetsat: ********************************************************************* Dear John, It has been brought to my attention that you require a Tellique software windows version to replace the one that you had bought from Tsystems. I am pleased to be able to furnish you with a copy. Could you please let me know your mailing address so that i may send out the software ASAP. I look forward to hearing from you soon. ********************************************************************* Of course I have sent my mailing address straight back, but I'm not sure why. As far as I know I already have the latest version of the software. I'll wait and see what they send me. Has anyone else had a similar email? -- Best regards, John mailto:kvp@bigfoot.com

David,yesterday as well! I would think that if the files sent were in groups ofis very rigid mounted. Even in a strong gale little signal variationI am trying to get a better understanding of this. I made a plot of the percent loss of segments versus channel number, expecting to find that the channel where the files which were larger would have a greater segment loss, and there was less likelhood of getting a complete file. Similarly I had expected that LRIT data would be more robust than HRIT data, but this also not seem to be the case when the loss was at its worst. It suggested that some file grouping was perhaps spreading the loss more equally across all channels. Guesswork, I'm afraid. I don't expect any file grouping to be constant, by the way. I (again) guess that there is a data stream and that all files of a certain priority will be packaged for transmission in some sort of "best fit to available packets" fashion. I don't know if the IMPF software processes files in a strict channel order, or if there are parallel processing tasks so the channel order for a particular segment is random. I should study the log files, shouldn't I? The Sky star card is in the computer in the garage!!.. and so perhaps is subject to a larger temperature variation than a "domestic" computer might expect to encounter? Cheers, David

It does all point to a slight alignment error, but how to convince the professional installers of this? How many months guarantee you would expect on dish alignment in any case? I would love to get the "professional installers" out again, but am worried that they check the dish, and say "It looks OK to us, that will be £50, please!" Cheers, David

lose signal rapidly. There is no better illustration of this than the recent move by BBC to Astra 2D with its much tighter spot beam allowing the BBC to go FTA. Thousands of Sky customers particularly at the extremes of the beam lost the BBC channels and it is reckoned that most of the problems were down to badly aligned dishes. Shoddy work by professionals.

Re: Missing Segments
David Strickland <David@...>
David,
Further to my post yesterday at 0830 I missed seg. 5 from chans. 6,8,9,10,11 and seg.15 from chan 12. The interesting thing here is channel 9 as it was amoung the groups of channels yesterday as well! I would think that if the files sent were in groups of channels then this is an unexpected result. Signal quality is a steady 70-71% with SNR 10.8 a 88cm dish weather is good and dish is very rigid mounted. Even in a strong gale little signal variation occurs. The dropped segments look to me like a software problem. The Sky star card is in the computer in the garage!! It has strong cooling and certainly no overheat problems. CPU temperature is a nice 44C and system temp is 28C. It has three temperature controlled cooling fans and as it is quite cool outside today nothing is working very hard. I have not restarted since yesterday deliberately to watch what happens. Regards David S.
