Hi OMs,
Yes, the Galileo spectrum null for both E6 orthogonal signals goes out on 1263.4 MHz. For that reason the P3E L-band receiver local oscillator is synthesized and receiver is possible to retune from 1268.800 to 1263.300 MHz (center of the analog passband) by command from the Earth. On 1268.52 MHz we expected one of the power spectral density peaks of Galileo sigs. I already offered participation on Eagle project in the field of L-band receiver.

Hi Mirek, OK2AQK
Tank you for this information and so as already published by AMSAT-DL in the following document
http://www.amsat-dl.org/pic/gallery2/main.php?g2_view=core.DownloadItem&... temId=6497
For the linear mode the uplink L1 will use 1268.725 to 1268.875 MHz while the Galileo Alternative L2 will use 1263.225 to 1263.375 MHz
Please confirm.
