Help needed for Tooway Ku band satellite install

Quote:

Basically the same as Ka but use correct carrier freq, click on the following links Eurobird3 carrier info and general install and activation info.

1472 or 1564 You can use your Horizon meter on Ku, we have a HEX file (shows a lock when found) for the old Horizon meter if you need it. Eurobird3 carrier info

Thanks for all the help, So all I need to do is key in 1472 and sweep away, how do I do the calcalating for L band in the cable? just in case I need it for the future.

Thanks alot for that will give that a go. I contacted horizon today and they sent me a hex file for this, It already has eurobird 3 33 on it is that not the same then?

Thanks guys, I will try it with the promax first as I found the KA sat easy using this, Just didn't know the if freq for KU Just thought it would be better to ask the pro's on this one.

If you use a Horizon hex file make sure that the person who made it knew you planning to use a 10 GHz local oscillator LNB, or alternatively knew that you wanted to look at an L band frequency of 1472 MHz.

A Horizon meter is an L band receiver (950-2050 MHz) and hex files will normally be made assuming that the LNB has 9.75 GHz and 10.6 GHz local oscillator frequencies and the polarisation is switchable H or V, using tones and voltages. None of this is true for a VSAT LNB with single polarisation and single local oscillator frequency.

Formula:
L band frequency in cable = satellite frequency - LNB local oscillator frequency.
e.g.  1472 MHz = 11.472 GHz - 10 GHz.

Polarisation setting:
For South Wales and Eurobird 3 at 33E and Horizontal nominal polarisation.
1. Set the feed rotation for Horizontal receive as the starting position. (LNB filter arm upwards or downwards)
2. Turn the feed approx -25 deg anticlockwise while facing towards the satellite in the sky.

Depending on the firmware software, the RX LED has the following meanings:

1 flash   acquiring
2 flash   ranging
3 flash   registering
4 flash   software download
ON    completed

or
slow blink   acquiring
fast blink     ranging / registration
ON    completed

very fast blink   modem fault

The modem will not transmit until is is receiving the correct carrier, which requires correct satellite and correct polarisation adjustment angle (also correct model number LNB i.e. with correct local oscillator frequency).

You may be on the wrong satellite (Astra ?) or have not set your polarisation accurately. There are many Ku band satellites. Slow single flashing in excess of 30 minutes strongly suggests wrong satellite or wrong polarisation angle.  

Try several satellites each way along the orbit. With Astra at 28E and EB3 at 33E, if you are in western europe, EB3 will be to the east and down a bit. Calculate the pointing angles for both and you can move exactly from one to the other.  The satellites are in a curved line across the sky, with top of the curved arc due south from your site longitude.

This page Tooway dish pointing gives you the polarisation adjustment angle (e.g -15.5 deg anticlockwise, while facing the satellite in the sky.) You can set polarisation angle using an inclinometer sideways across the BUC or LNB. Make small adjustment if asked to do so by the hub.

Also, for people with the Ka band Tooway service on Hotbird,  this page gives the actual polarisation scale number to use on the blue scale behind the Raven dish (which has non-standard polarisation scale numbering)

Best regards, Eric.
