Hub with 4 SDR - Port mapping configuration

Hello, The SDR do not fit in the RPi and I am using a Hub (like the image) with the 4 SDR connected. I am not receiving anything and I wonder what is the configuration I have to set in the Port mapping. Does the Hub need to be in the Port number 1?

Thank you

I believe it’s usually plugged into Port 4.

Though I’m not sure if every hub model is supported.

USB extension cables are also an option if you’re only concerned with the physical space needed to fit the dongles.

Please be sure to read FUNcube sample rate dropping and disconnecting - FIXED - #2 by TvE and the post after it. The 4 FCD on one hub will only work if the hub is a Multi-TT hub. If you have an rPi 4 the hub should be plugged into the top USB3 (blue) port.

Thank you Josh and Thorsten, I pluged it in the port 4 and it’s working, althought the Tags and pulses does not show my tags, I see the graphs detecting the pulses and it detects 4 Radio ports. Is it then correct I understand?

Thank you

The chart shows tag detections. They should also show up in the “tags and pulses” text panel, but sometimes when it’s empty you have to refresh the page for them to show (there’s a bug).
