Hey @cgbsat:
I saw that you’re using a L band antenna. Can you show some results?
It’s not an L-band antenna that I’m using but S-band instead. The antenna, a 3.5 turn helix, and the G4DDK preamp are tuned to 2250MHz. Back in April, Pierros and I did some experiments with the TT&C beacons of the CartoSAT satellites, and the observations are in the database. The best examples are below, where you can see the TT&C beacon. The broad curved signal is the DC offset, as the 100kHz LO offset is not sufficient to keep the DC curve out of the observing window.

Interesting. Thank you for the informations. What kind of RX did you used at this time?
