I am having some issues with my HX50.

I am in Iraq, my signal strength has been at 92 for months, everything has been working just fine until yesterday when the system was going in and out.

Weather has been fine, dish is still at 92 signel. It seems to pull up google 95% of the time but anything past that doesn't want to work.

Been getting

Terminal Receive Error (603)

Web Acceleration Client Error (509.2) - Upstream TCP Receive Failure (Web Server)

from time to time along with a couple others, been writing everything down

This suggests that either your dish moved, or something's partially blocking it. I'm guessing those errors you're seeing are caused by the resultant packet loss. //greg//

I have the same issues as you. I have had good service up until yesterday. Now I get DNS errors and when I ping it only get a reply 25% of the time. There site says everything is okay but something is not okay. Does your Accelnet work. I do not use it that much but it does not connect to the server anymore. And my strenght is also always 88-91.

Looks Like Things are back up and running, just got off work so good so far.

Actually - assuming an earlier BW statement that 9/10 rate not being available still holds true - the ModCod is ok. It's the FEC part of the Rate Code that warrants attention. The first stat suggested it could have been on the verge of falling back to 128k. By comparison, my SQF is currently 83, with (the max authorized) Rate Code of 256k 4/5 (TC). SQF and Rate Code recovered somewhat in the 2nd set, but FEC remains short of the desired 4/5 rate. POL angle maybe?

Plus - both sets of stats reflect a very short uptime. I'd be curious why it appears this modem restarts more than usual. Mine runs for weeks at a time without ever seeing a restart. Last time for example, was 11 days ago when I swapped out an UPS.

Regarding receive signal quality at a remote site (SQF)

If the value has been around 92 for a long time and now is around 82 then something has changed, e.g. lower transmit power from the teleport, rain fade at teleport or remote site, cross pol carrier started interfering, and quite likely: remote site dish has become mispointed or LNB cable corroded.

It is important to point dishes accurately to the maximum SQF value, whatever that value may be. � Different networks (e.g. Iraq and USA) will have different peak values as will different sites in the same network, according to location in the downlink beam pattern. �Just to get the value above some idea of a good enough signal (e.g. 75 or more) is not acceptable. �The reason is that you must get the receive beam accurately centered (peaked SQF) so that the narrower transmit beam is centered also. �When the satellite downlink power is very high is quite possible to have good quality downlink but still be mispointed so far off that the remote site uplink is struggling. �This being indicated by it having to drop down from say 4/5 to 2/3 to 1/2 rate code. This should normally happen only during heavy rain to keep the service working.

When I saw the first posting above (Receive SQF reduced from 92 to 83 and transmit Rate Code down to 1/2, my thoughts were the same as Greg: �Dish mispointed causing both receive and transmit to deteriorate simultaneously. Water inside the feed horn or obstruction can cause simultaneous deterioration in both directions.

sooby25rs � Can you tell us what was done to restore your SQF back up from 83 to 92 ?

Best regards, Eric.

My issues with the system first started 2 or 3 days ago, before we had a storm come through last night. When I posted the first time with th 82 was during a little ran before the storm came in, I said I normal have a 93 because the system for the most part has been running for the past 3-4 months with no major problems. After the storm came through it moved my dish about a inch or so enough for me to lose all signel... Seeing as I had to go to work I shut the system down to work on it after I got back, started everything back up moved the dish a inch or so got my singal back to 91, the system updated and restarted and thats when I posted the system stats, that being the reason why the short up time.

I don't have the dish itself polarized but instead I have my LNB at the 45ish degrees nagitive i think, been thinking of changing it to have the LNB at 0 and the dish canted?

If you have the modern 1.2m Prodelin dish with a large polarisation scale on a grey wedge shaped plastic boss behind the dish and a feed horn throat marked with a "505", then..

The feed horn must be set so that the 505 is always directly away from the feed arm. �The fat lump on the opposite side of the feed throat will be directly underneath towards the feed support arm. �This applies regardless of polarisation setting.

The polarisation should be set by turning the entire dish.

Best regards, Eric

Worth doing if your feed horn throat has "505" on it. Set the feed horn so that the "505" is directly away from the feed support arm, then turn the entire dish for the polarisation adjustment (assuming a wedge shaped boss and giant circular polarisation scale behind the dish).

If your feed horn throat does not have "505" on it there will be no benefit. The tiny picture on this page satellite dish pointing angles Iraq shows how the LNB will look as viewed, with you standing behind the dish and looking over top of the dish towards the satellite. The exact polarisation adjustment angle is given for your location.

Best regards, Eric.

Earlier you said you were set at "45ish degrees nagitive". Since you've only generally described your location as Iraq, I don't know how accurate the 45 part is. Be aware that to minimize phase distortion and adjacent satellite interference, the POL angle should be accurate to within 1 degree. But from anywhere in Iraq to W3A, the POL angle should be positive. That is, rotated clockwise as viewed from behind the dish. That holds true regardless of whether you rotate the TRIA or the reflector itself.
