Setting up HX50 in Iraq: RSL=15 ?

It's been concluded here, that a RSL of 15 on the HX50 indicates "no signal detected". Typically this issue is related to antenna pointing - but - the InDoor Unit (IDU) has to first know the signal parameters  specific to your connection. You should have been given those parameters by your provider.

So - has your assigned satellite/transponder/symbol rate/polarization/FEC/et cetera been loaded into the IDU yet?

Check your two coax cables; they may be crossed over.  

Power off.

Disconnect the rx and tx cables at the modem.

Examine to check the pins stick out 2mm.  If possible check the braid makes good contact and no fragments of braid are causing a short circult.  Reconnect the rx cable at the modem.  Make sure the pin actually goes smoothly and fully into the hole and does not push back the cable.  Do the F connector up carefully and fully and firmly but not so hard as to break it inside.

At the antenna end disconnect both cables and examine the F connectors as above.

Trace the route of the cables and identify the rx cable at both ends.  Connect up the outdoor end of the rx cable to the LNB which is the small white module on top of the filter.

Power on and the "15" should now be a variable that changes according to where the antenna is pointed.  You must have entered the frequency and symbol rate etc for the modem to display wanted carrier signal strength and to lock onto the satellite carrier.

At the back end of the transmit BUC module are two F connectors marked IFL (inter facility link cable) and AP (antenna pointing).  There is a black cover on the AP connector.  The IFL (inter facility link cable) is the one to be used for the transmit cable (To SATellite).

Power off before connecting up the transmit cable.

If you are in Iraq and aiming at W3A your dish should look like this:

Study the picture closely. The 505, the single tick mark, filter and LNB all exactly and directly away from the feed support tube.  Fat lump on feed throat towards the feed arm.   Entire dish then turned about +42 deg clockwise, using the giant polarisation scale behind the dish, while facing towards the satellite.

Best regards, Eric.

Hi,

Please feel free to contact Bentley Walker for support with your installation.

Study the picture above closely. The 505 and the single tick mark must both be exactly and directly away from the feed support tube.  The fat lump on feed throat must be directly towards the feed arm.   For horizontal receive polarisation (HX W3A service) the filter and LNB must be at the top.  The entire dish must then be turned about +42 deg clockwise, using the giant polarisation scale behind the dish, while facing towards the satellite.

The feed horn throat has three tiny slots inside, on the side towards the feed arm.  These slots make for a complete dish with much superior cross-pol performance, but the feed must be oriented with the three slots towards the feed arm.  The slots are inside the fat lump of metal.  The slots cause 'negative' cross-pol that cancels out the cross-pol caused by the offset geometry of the dish.  If you put it together wrong then the cross pol performance will be far worse that a non-compensated system.

Please get it right, I spent many $10,000 getting these mode-matched cross-polarisation cancellation feeds developed by Barry Watson at ERA in the late 1980's.  An offset dish with a mode matched cross-pol cancellation feed is as good as a dual optics antenna, but at lower price.

If at some future date, for a different new service, anyone needs to operate vertical receive polarisation with these feeds the assembly procedure is: The 505 and the single tick mark must both be exactly and directly away from the feed support tube.  Attach the filter/LNB to the tapered adapter tube so that the filter is at the side.

Best regards, Eric.

You are welcome.

A receive level of 15 is definitely unworkable.  You should get more like 90 to 100.

Please send your ideas as to what might be wrong.  Please also send images of your dish dish feed, view from side, front, rear etc.  Please send copy of your config document also.

Send to eric@satsig.net

Best regards, Eric.

If you move a VSAT you need to tell the hub the new lat and long and repoint the dish using new calculated elevation, azimuth and polarisation angles.  

Line up the dish with only the LNB connected until you have a perfect receive signal.  Power down.  Connect the BUC and then, after permission from the HUB, power on.  Talk to the hub while they check your site.

Don't move a site without telling the hub, otherwise your range will be wrong and your transmit burst timing wrong.  This causes you to interfere with other people and also prevents your own service working as others interfere with you. Bursts going up to the satellite need to arrive in sequence, not overlapping.

Having said all that above, for the record, now to you immediate problem.   Your low 15 signal is almost certainly due to you not having yet found the satellite and peaked up.  Finding the satellite takes anything from 10 minutes to 2 weeks.  Peaking up always takes at least 30 minutes.

If you are in Iraq and aiming at W3A your dish should look like this:

Study the picture closely. The 505, the single tick mark, filter and LNB all exactly and directly away from the feed support tube.  Fat lump on feed throat towards the feed arm.   Entire dish then turned about +42 deg clockwise, using the giant polarisation scale behind the dish, while facing towards the satellite.

The next image, below, shows how to set the beam elevation angle. This example shows the beam elevation set to 48 deg.  You need to calculate and set the elevation for your new location using dish pointing in Iraq.  The metal plate behind the dish is at right angles to the beam direction.

You can make your own inclinometer like this by printing out page how to make an inclinometer
In Iraq, your beam elevation angle will be between 32 deg and 37 deg for pointing to the W3A satellite at 7 deg east.

Best regards, Eric.

With 15, you are not receiving properly, probably not pointed at the satellite, LNB cable fault or have the wrong tuning / symbol rate configuration in your modem.  The frequency / symbol rate may have changed if the modem has not been use for some time.  You need a new configuration sheet from a service provider with  frequency / symbol rate and IP addresses etc plus name of satellite and nominal downlink polarisation.

Contacting the hub, depends who is your service provider:

For Hughes HX service try
Bentley Walker (UK) +44 239 231 1118

or their local Middle East service provider
WAFA (UAE) +9712 633 4211

Ok I did alot of calling even to that +44 number and the one in U.A.E and now we are at 86 and transmitting, does it get any better than that our just I just be happy after all it is working.

How many people can I put on this system, different accounts that is?

The Information that were givien for example the 1 watt compare to the 2 watt is different from what is on the system along with the reveiving polarization, on the computer it is horizontal on our paper it says it should be vertical.

I really do not know what all the setting on the paper means all I did was plug it in but now it is different.  I just want to know how that would affect things. 

Just want tosay thanks for all your help.  Both from this website and from the techs.

If the ESN number is the same as serial number it is 1342000.  That is the only number I see that is close to what you are asking.  Email.  rebuilding.rasheed@gmail.com

Eric,

I would like to know how many different accounts/lines may I have for this system without causing it to run slow. 

Thank you
