That's pretty interesting. Now an extra satellite meter has just arrived, on Saturday I should be testing my own 45cm x 35cm dish, and able to compare it against my 1.1M dish, and against the calculated differences in gain
Es'hail-2 beacon frequency (non-amateur)

Hi,
With my 3m dish i can just rx es'hail 1 transponder.... but it may not rain…. i had to place extra sat amplifier to have lock in shack. it is very difficult to aim the dish !!
-
try one of these transponders Badr, 26°E beam BSS
11938 V 27500-5/6
11958 H 27500-5/6
11996 H 27500-3/4
12015 V 27500-3/4
12034 H 27500-5/6
12073 H 27500-3/4
12226 H 27500-3/4
ciao, Lucio

can someone confirm transponder on 11270H 27500 is still active?

That does not surprise me... with my 80cm I cannot receive it at all.
At 26e I do receive a couple of transponders on Badr but these are on a European beam ('BSS') not the MENA or Africa beams of those satellites.
As Es'hail-2 has only MENA beam according to their website, I do not expect to receive it at all (on DVB).
Apparently the beacons are on a wider beam. And of course, so is the AMSAT transponder.
-
I confirm. 11270 there are two active transponders. Vertical and horizontal. Same position at 26°E
-
I use the 2.4 m offset antenna, Octagon LNB (20 m RG6 TV cable) without the GPSDO and Signal Hound SA44B spectrum analyser.

@ PE1CHL and ON4BHM
in south east Germany (JN58xx) I can receive all BSS BADR4 transponders with my 85cm offset dish (strongest one is 11996 H (e.g. Deutsche Welle), but not the mena beam. On 11.270 I can see just a slight higher "noise" in the spectrum of about 35 MHz width - maybe that is the rest of the signal of the transponder from ES Hail 2 TV-Test pattern ???
-
I0LYL what dish size do you use?
-
I0LYL is in sardina (if I'm right), thus he is in the "offical" footprint of the MENA beams.
-
sorry, I update the profile. I am south of Rome and I am at the limit of the MENA beam. My locator is JN61FQ. The dish is 100 cm offset, LNB Octagon OTSLO.

Nice set-up, and thanks for providing the details. It sure had to be something big!

Here is a waterfall plot of the 10706 beacon received using unmodified Octagon LNB and RSP1A SDR driven by HDSDR, audio fed via VAC to WSJT-X. Dish = 0.3f/D 3m, underilluminated.
The straight trace is a GPS locked signal generator at the IF, showing that the RSP1A is stable. Looks like the unmodified Octagon would be adequate for SSB operation, with a little retuning from time to time! Assuming of course that the transponder LO is as stable as the beacon!

Hi
Since 1/1/2019 i was monitoring the EB on 11205V
Today i made some new measurements and noticed no change in Azimuth or Elevation for the last 4 days
Further Eshail 1 is on 25.5 east, while Eshail 2 is at 26 deg , so exactly 0.5 deg more to the east
Used RX setup is an Andrew 4.9m Esa Earth station
More reports comming

Some tests in GG77 Resende - Rio de Janeiro.
120cm dish + LNB Avenger PLL 321 + RTL.

Congratulations!!! Looks really nice...
If I counted correctly, we will have at least 3 operators from Brazil
PY1SAN, PY2SDR, PY4ZBZ
Meanwhile our JAMSAT friends are supporting RAST Thailand to install a P4-A station at the RAST headquarter at the Bangkok University which they hope to have ready by March.
Lot's of DX expected-- from Brazil to Thailand..

PY1SAN good job Sandro.. I also found your video on youtube and want it to share here for the group. It includes all the details

Nice duoband-solution. The RX seems to work very well.
Did you test the Helix feed (of course NOT in direction to 26E ;-)) ) - is there interference of the TX-signal on 2,4 GHZ with the reception of the LNB ? What about the loss in gain because of the helix-feed is "to close" to the dish and not really in the focus ?
Any information and data would be appreciated.

P.s. thanks to Heiner for posting the Youtube-Video !!

According to the literature, the phase centre of a helix is located very close to the reflector plate of the helix, so having the downconverter looking through a hole in the reflector plate should be OK.
The helix will cause some blockage on receive, but probably not enough to cause a problem. I have a similar feed with 2.25 turns for a prime focus dish and it seems to be working fine on receive.

Thanks for your comment. Probably i will test TX this week (with dish other direction). I don't have some basics equipments to measurement 2400mhz. However i also believe that i will have an big desense or saturate my LNB.
I will test with 5 watts.
