Es'hail-2 beacon frequency (non-amateur)

Early this morning the two EB's were present here.

However, when I looked at my screen at 09.30z the

beacons were absent. Turning the dish didn't help.

I'm still able to RX other beacons from other satellites.

Hello !

I confirm that the signal is weaker this morning,I find the lower beacon 10 to 15 dB lower than yesterday.I cannot see the two modulation signals ,only the career is visible 10 to 12dB above local noise,some thing strange ,the level of the beacon is stronger with 14V supply (like V-polar) than 18 V corresponding to H_polar !

I think the satellite is no longer in the same position

To get the same signal back, you need to rotate the disk to the east

I think the last picture (lower one) is ArabSat 5A at 30.5E @10706 MHz.

the last keps, at 20:12 UTC, tell us that the satellite is still at 24° E

According to Daniel Estévez ea4gpz Twitter https://twitter.com/ea4gpz
Es'Hail-2 beacon still transmit but power is reduced by 25 dB.

Another Interesting observation:

Es'HailSat homepage have coverage maps and non of them have beams to Europe.

So, in theory maybe MELCO/Es'HailSat engineers are already using P4A antenna for beacon and IoT tests.

You were right, Remco,

there is another signal at 10.706 GHz coming from an orbital position above 26 degrees.

And I had used that to align the disk.

Compliments

IK8XLD I guess you were listening with horizontal polarization. In H-mode I have two carriers from ArabSat 30.5E @10706. In V-mode the left one almost disappears here.

Try 11199.8H 25.5E (Es'Hail-1) to point your dish.

After correction I determine 11199.796503 MHz (+/- 1 Hz, middle peak) as frequency.

Hi Remco,

thanks for suggest, I'll try later.

I have just poined BADR 4 using this channel.

Tnx again.

And these are the signals at 11.199.8

Hello All,

Have just joined today after having monitored your discussions for a while.

I have installed a 1m offset dish yesterday with an OSLO Octagon, and R820T2 USB dongle.

After some tweaking, can receive the upper Eng beacon at 11.205 with fairly good sigs, as well as lower beacon carrier with a lower level.

Hope that all this will allow sufficient level once the transponders will be activated...

73, Pat

sure that this is the Es'Hail beacon?

Looks like the Astra 23.5 ° beacon ...

73´s de Robert

I have this strong one, which I suppose is Astra2c at 10.951.5...

Do you think I'm wrong somewhere ?

thanks

Hi Pat,

I'm guessing your 10706 Beacon is Es'Hail-2. Your 11205 one is more likely Astra @23.5 East, unless they have turned modulation on 11205 (up until now it's just been a pure carrier from what I've seen, and I think yesterday or the day before it dropped 25db, according to some). Your 10951.5 waterfall is almost certainly Astra 2C

Merci,

Then this means that I should better aim the dish based on the 10.706 beacon, right ?

I did not find other beacon at 11205 based on http://frequencyplansatellites…pe-Africa-MiddleEast.html, except astra1kr, but did not think it could be it, since is at 19°.

I shall probably wait now for sat comissioning before climbing on the roof and adjust

At least, this works !

Guys! Did you tested Es'Hail-2 beacon polarisation?

ea4gpz cail that 10706 MHz beacon now have vertical polarisation.

Hi,

I have it on V pol on 10706 (see snapshot a bit above), if this is it ...

Finally can find a single carrier at 11205 H, whereas the wide beacon I have on same freq V pol seems to not be the right bird...

Here is how I check I'm not receiving Es'hail-2.

Provided that you're 'on frequency' (i.e. you know the LO frequency/frequencies of your RX-chain. Can be checked with e.g. a Baofeng tuned to 446.085 MHz) the following procedure may prevent fooling yourself.

Information is now that the 10706 MHz EB is 'vertically polarized', i.e. it is received stongest when the LNB is in vertical mode.

The following situation / sequence of events is assumed: The LNB is in V-mode (12-13V), a RTL-SDR (or similar) is used to receive the IF-signal from the LNB and one looks at the waterfall while pointing the dish 'ins Blaue hinein' while 'suddenly' a signal (around) 10706 MHz is observed.

Align the dish for max signal and also tweak the skew of the LNB. The skew angle is counter clockwise where I live. When your longitude is >24 degrees (IOT slot at the time of this writing) the skew angle is clockwise.

Zoom into the signal until you have <10 kHz frequency steps in your waterfall.

Place your hand in front of the LNB. The signal should disappear. If not, it may be a birdie (and hence you're NOT receiving Es'hail-2 ; -)

Put the LNB into H-mode (applying 18 - 19V) .. OR.. rotate the LNB 90 degrees counter clockwise. If another signal ca. 2,3 kHz lower in frequency appears, you are NOT receiving Es'hail-2 but ArabSat 5A at 30.5E instead.

Right now: Es'hail2 10706 vertical, 11205 horizontal.horizontal.
