sorry, I had not seen this thread yet and put the same picture back here.

after two days of testing, with the operating transponder I can state that an unmodified Octagon LNB is perfectly suitable to receive the SSB, CW, BPSK telemetry and even JT65.
We followed satellites with fear doppler and spin modulation and we never gave up. That little bit of drift does not scare us.
Maybe I'll put a hood on my unmodified LNB, but I will not do any more.

In the Mailbox-F7 of the AO40Rcv program, telemetry appears in addition to the text message.
The telemetry is certainly generated on the ground. Where I do not know.
Note that all the other functions of the AO40RCV program are not consistent. We can only read what appears in the Mailbox-F7 and in Signal-F1. The rest is not valid.

Hello,
on the transponder noise there is no QSB.
...

so good. ignore any signal unrelated to official tests.
-
I do not see QSB. Stable signal.
Perhaps your dish is at the limit and there is a strong wind at your home.
Here 100 cm Offset dish Octagon LNB

Please carefully read the following announcement :
https://amsat-dl.org/en/eshail…100-teleport-inauguration
Please be patient and DO NOT TRANSMIT during our commissioning activities. Otherwise the opening of the transponder for general use might be further postponed..
Thanks!

...there is someone who does not read.
-
according to what was suggested by Peter, we ignore any signal extraneous to the tests.

Goonhilly...I have a problem!
I cannot log on into the chat...
I have tried all possible combinations but no luck!
help please!

last summer from my holiday home I took part in the DSLWP-B tests. It was a good experience even with all modest equipment.
The hamradio experiments are still ongoing and will continue until August 2019 when the satellite DSLWP-B will be dropped abruptly on the lunar surface to avoid leaving space debris in orbit.
Some interesting links about the HAM Radio part:

zhaofeng, maybe your dish is aimed well at 26 ° E but the skew is badly set. Make a verification. and let us know if this data is correct for your QTH.
Unfortunately, the TV channels you receive do not receive them and vice versa. From Rome I can receive the channels broadcast on MENA BEAM while you receive the channels broadcast on Central Asia BEAM. We can not confirm with you on these TV channels.
The same for the beacons. From 13 January 2019, the beacons of Es'hail-2 are broadcast on MENA BEAM (Middle East North Africa). Are they coming up to you? Again, check the SKEW LNB.
If you can not, do not worry. When the Qatar-Oscar-100 (P4A) transponders are turned on, everything will be easier.

Just an image ... Same result.

Remco, Simplex MODE???

grazie Lucio, ma usavo gia' un'antenna a elica solo in RX x AO-40 ai tempi, non sono nuovo a questi temi e il sito e stravecchio, anche se con nozioni utili, cmq cercavo o meglio cerco ancora info per le PATCH antenna.
Cmq TNX....

ero settato sulle eliche e ti ho dato l primo link utile.
Parti da qui e vedi se ti è utile.

...also because my first helical antenna I built it exactly 42 years ago, for AO-7.
-
Remco, in my garage I have already built three antennas, with different solutions. With more turns and with less turns. At the end I will decide what to mount in a fixed place. This one of Winkler will serve as a reference, or I will modify it. We'll see what to do.
In any case, there was no mention of G8HAJ's backfire helix.

With P3-E unfortunately no progress. The hoped launch opportunity in US did not materialize..
best 73s Peter
maybe we can ask a ride to Elon Musk for the next test flight. Together with Tesla our satellite would be in good company.
-
HI Peter,
the photo I put is taken from that forum. Maybe I should report it. I ordered this helical feed but I have not received it yet. When it will be in my hands, we will do some measure. The mechanical solution seems good and also economic. @IW9EZO
Forse vanno svitate quelle due viti, tolto il collare, avvitare il connettore e rimettere il collare. Come dicevo non è ancora arrivata e quindi le mie sono supposizioni.

For those of you who want to buy an uplink antenna for a dish off the shelve I recommend the antenna from Winkler: http://www.winklerantennenbau.de
38,70 Euro plus S&H

I think it's the same model?
