friedtj at free.fr friedtj at free.frwonderful pictures. What NFM settings do you use ? surprisingly I had better results with excessively narrow settings (5 kHz bandpass, 1 kHz cutoff bandwidth) compared to the expected 45 to 50 kHz wide setting expected for this mode. I am leaving mid-september for some remote northern area and would love to take the EZCAP with me to demonstrate satellite reception using lightweight equipment (as opposed to a dedicated receiver + car battery).

The DAGC is disabled by default in current librtlsdr, so if you use a recent version you should have no problems. In fact, my reception was fine when I tried it (even without LNA).
