Uh, are we back with the misunderstanding and false assumption that APRS-IS can be used for propagation analysis?

Remember, the APRS-IS _always_ discards all but the first-received (by the APRS-IS backbone) copy of any given packet. So, if multiple I-gates hear the same packet, only the _earliest_ I-gate's copy of the packet will get through to APRS-IS receiving clients. Period. You can't make the APRS-IS send duplicate packets from a slow I-gate.

Please keep this in mind when designing your APRS-IS client.

But the received traffic can be seen in the screenshot of the console in the previous post?

I don't know what to say here other than aprs.fi is not showing any real heard traffic from your station.? I would assume this is a levels issue with your SDR or an I/O issue between the SDR software --> Direwolf.? In the terminal window that has Direwolf running, you should be seeing decoded packets from all of the packets stations on frequency.? If you're not seeing decodes, this again points back to a form of "audio level issues".?
