New Tooway install La Coruna (Spain)

Hi, please contact us if you need help. It looks your pointing needs some fine tuning. I dont know where you are located in Caruna but signal strengt should not be a problem but you are a bit on the edge of the footprint so maybe a bigger size dish (98 cm) will be finaly the best solution if signal stays weak. http://www.europe-satellite.com/EMS/popup/footprint_tooway.htm

Before making any adjustments I suggest you paint white one flat on each of the fine adjust azimuth bolt and elevation nut. Also measure the length (to 1 mm accuracy) of the outer end of the elevation screw and the position of the azimuth fine adjuster. Write it all down and maybe take a close up photo.  Wait for clear sky conditions.

If someone can say how to read out the signal quality then you need to turn the nuts in 1 flat increments (1/6th turn) recording the signal value at each step.  Go down a significant amount either way, plot the curve, then calculate the centre position and adjust back by the requisite number of turn and flats.

If there is no method for determining signal quality count the turns and flats till the demod unlocks.  Record the count of turn and flats.  Then put back and wait until fully stable again.  Then go down the other way and note the other unlock position.  You may need to repeat the above measurements several times.  Calculate the centre and move there by the requisite number of turns and flats.

Do the above peaking up process in elevation first since it is easier, as there is no backlash.  In azimuth the method is more complex since you must gradually approach the final setting in a specific direction, having removed the backlash.

It is no good just to get a "good enough" receive signal.  The "good enough state" applies over a wide range around the beam centre.  You need to get to the exact centre of the beam by halving, as the transmit beam is significantly narrower then the receive beam.

It is normal for an experienced installer, with the proper test equipment, to spend at least 30 minutes peaking up, after finding the satellite.  It is a precision skilled job.  You may take much longer.

Best regards, Eric.

Please explain how to see a receive signal quality on an operating service ?

If he does not have a spectrum analyser or a power meter then a receive quality readout from the modem would be helpful.

Best regards, Eric.

As stated above, you only get to view the set up parameters the first time you log in. There seems to be no way to subsequently check your SNRs.

For this reason, a good meter or if you are very wealthy, a spectrum analyser is required.
A reasonably priced satellite meter is fine with a bit of practice but you can't read that initial activation screen after first log in.

Hope this helps.

Regards,

Tony

Ask your service provider for a graph of your Tooway uplink and downlink C/N over the last week.  If it is varying with a 24hr pattern then it could be that you are mispointed and on the side of the beam and the slight daily satellite movement makes it vary.  Irregular changes may be due to weather at your site or Turin. Offline when you were switched off etc.
e.g.


It is really bad that the customer can't read out their own downlink C/N.  The information is there in the modem and is being regularly sent to the hub.

Best regards, Eric.
