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

.. and keep in mind that what you are seeing has nothing to do with the AMSAT transponder. Even the antenna beam is completely different..

But still, it's a good training and reference to compare and optimize your downlink antennas and equipment for next year...

Hello to the group !

Is there any sign of life of the different beacons this afternoon ?

Using here 80cm dish with sdrsharp .

Hello Renauld,

Both Es'hail-2 engineering beacons on 10706 MHz and 11205 MHz are still active.

Hi,

the satellite has been moving measurably to the east since yesterday

Turning the antenna to the east a few tenths degrees again brought signal maximum

The side lobe of 33.5 ° satellite has dropped significantly

... and, on 10.706 is at times activity

I confirm, the satellite appears to be moving rapidly towards 26°E

Hello everyone,

Actually it moves ...

It may have been moving all the time.. NORAD data is not real-time and sometimes they just propagate the elements by calculation and not by measurements. So if you see a big Jump in the elements, it may be due to the fact that they have made "real measurements". I remember that Victor Kudielka OE1VKW, James Miller G3RUH in the past found out that sometimes we should not trust Keplerian Elements, because they are only "spot measurements".. Indeed, things might have been improved over the last 10 years.

But for sure Es'hail-2 will arrive at 26°E somewhere in January.

Thanks for the information Peter.

It's like, I will not do it again ....

73, Charly.

Peter, I agree with your considerations but in addition to the keps I'm also checking the signals from the satellite and with my dish fixed at 26 ° I see that, since yesterday, there is a strong increase in the signals on all the frequencies of Es' hail-2.

If this is the beacon of Es'hail-2 I'd never received it so loud before.

Hi Charly, there is absolutely no problem, many thanks for your report!

I just tried to explain how it works with Keplerian elements.
I think someone with a huge dish already confirmed that the satellite maximum is a little further to the East.

Well, interestingly I also have maybe 6dB more signal compared to the last several days and I did not move my antenna away from 24.2°E

Hello,

I also observed a few dB-s stronger signal when corrected antenna in east direction. 73,Viljo ES5PC

Thanks for all infos !

Here is what i get on the screen with a 60cm dish and a rtlsdr dongle.

Is this the good bird ?

Hi It is cold outside...

Yes, it looks like correct signals. Congratulations! There seems to be only some frequency offset in your downconverter chain. With the LO locked to a rubidium clock reference beacons are currently only less than 500 Hz away from their expected frequencies.

Hi. You have the bird correct.

Hi all,

First attempt here this afternoon ...Octagon OSLO single LNB without modification, 80cm offset dish, FUNCUBE Dongle + SDR.. Rcvd 11205 Beacon and 10796 also. Great !

73,s de Antonio

I can also confirm in Sardinia, the signal was dropped about 7/8dB. Now the maximum signal is on 26E. +12dB 10706 and about +10dB 11205

Also is active now the DVB-S transponder 11270H with "8 TEST channels- coming soon"

Viewing the webtracker Es'hail2 seems to be moved from 24E, now is on 24.7E and still moving

I made a cross-check, when I moved my antenna to 26°E the signal is much weaker (where I have BADR-4 transponder at maximum). I had my antenna previously around 24.2°E and can rotate it in 0.1° steps.. It might be a few tenth of a degree more east now, but I tend to believe that also the power level was increased..
