  3. Description of your issue:

I have 3 identical setups/devices. For 2 of them, the RF spectrogram (/rf-spectro.jpg) is almost always complete (+/- > 800kb). However, with one device, I never manage to obtain a complete diagram; usually, it is a maximum of 400kb, and the rest remains gray. Even with a new/different SDR, new cable, and new antenna, the behavior remains the same. I suspect, but cannot confirm, that this affects or makes the reception incomplete.

Should I assume that under these circumstances I cannot fully see all potential OGN transmitters, and if so, what is the cause of incomplete spectrograms/how can I further debug this? Could it be due to the device's load/lack of processor time?
