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

  • Yeah, I have approximately the same response here. However, I find it surprising that you there in Brasil are able to have such good reception with lower elevation angles (thus relatively more 'hot earth') and more atmosphere.

    Thumbs up!

  • Based on recent data from 10GHz EME experiments with the moon at low elevations at one end of the path, there should be little or no degradation at 10 degrees elevation for most of the time. This data applies to a 1.13m dish at the receiving end - smaller dishes will suffer additional ground noise at higher elevations than larger dishes, but at 10 degrees there will still be little additional ground noise. More info on these tests is in Dubus 4/18 p 118.

  • Hello,

    only a little question from a new Forum-Member:

    this Day i can hear 2 beacons ...

    first on exact 10.450, the second on 10500.

    Both are verry clear and loud.

    Can anybody verify and confirm this, or is this a Problem in my Setup ...


    Standart-PLL-LNB 80cm offset iCom ic-r7100

    JN59MF DL/Bavaria/ Roth

    mni tks in advance, Andy

  • More likely a multiple of 10MHz and/or 25MHz within your system (LNB may use 25MHz). Correct frequencies are 10706 and 11205 MHz for the Engineering beacon.


    You can confirm by:

    o Moving Dish

    o Switching Polarisation

    o Putting your hand in front of the LNB


    If they don't change, then they are local to you

  • Hi All


    I set an offset 120 and LNB last friday and the signals of both beacons are very strong here. So it must be I'm in the "good" footprint of the sat. My locator is IM98wn, Benidorm, mediterranean coast of Spain


    10706MHz beacon V pol. With some QRM, probably local or LNB issue




    11205 beacon H pol a bit stronger. More than 35dB over noise




    It is very important to rotate the LNB to the proper polarization shift

  • Hi all :)

    Unfortunately, i cant receive the beacon at 10706V.

    There is also absolutely nothing at 11205H.

    But i'm able to receive the two beacons next to it.

    I'm located in the north-west of germany. (North Rhine-Westphalia)

    I'm using a 2,2m PFA dish (solid)


    I think that i've pointed the dish at the right location, i can receive the 12245V DVB-S2 transponder of 26°E with 12,2dB. (Alkass one/two/three HD)

  • Mark,


    I've not seen the 11205 beacon here in G-Land for a while (It is believed that they may have switched to a narrower beam a week or two ago). However, during the time they switched, and afterwards, I could see an increase in the noise floor while they were testing the NB and WB P4A Transponders.


    The fact that you can receive beacons of _something_ suggests your system is good-to-go (pointing adjustments with a 2.2M dish aside, you may need to tweak things, I know I will, and I only have a 1.1M)


    I think we just have to be patient now, for the spacecraft to be handed over to the operators, and then some time after that P4A testing will begin. I'm sure Peter and Achim will keep us updated as and when there is something to tell

  • Hello,

    Here in JO45 I have Es'hail-1 11199,8 MHz beacon with 22,6 dB S/N in 500 Hz BW. Using 85 cm offset dish and Octagon OSLO (no frequency stabilization). Using RTL dongle and HDSDR for demodulation.


    I believe most S/N reports are referenced to 500 Hz bandwith, although not always stated. Otherwise difficult to compare numbers :)
