Look at AMSAT-EA's homepage https://www.amsat-ea.org/. Look also the YouTube video, I was very impressed of the return of the first stage to earth. The moderator lady spoke about a launch of 105 satellites.

If you receive my paper QSL card I will write as follows:
Mode: "SSB SAT"
Locator: JN47CK is fix on the card
"Via QO-100" as note
I think that's OK. i'm angry about OM's who have the note "Live is too short for paper cards" with a tombstone on their QRZ-site!
CU on QO-100 next year when the weather is nice and warm.
Season Greetings

May this article from Matthias, DD1US, help you. The easy way, which I did, is to mount a LHCP helix feeder on top of the LNB.

Here are 212 items available, good luck.

Sorry for the photo - here is the full one.
No, it was my fault. But if you photograph the helix horizontally with the socket on the left side, then you can follow the wire with your mouse pointer. Otherwise you have to move the helix in your mind.
-
OK, it is LHCP. The helix was unfavorable photographed, an optical illusion was a result by me. I found a good site in the meantime:
Sorry for the confusion, I was also confused.
-
Oooops Sorry. I made the mistake and looked from the socket.
