[AMSAT-BB] Sent AX25 from on PC to another through icom9100

Hello,

I tried to send an AX25 packet via an icom9100 by passing through a soundmodem which is installed in a first PC (PC1). The PCs 1 is connected to the icom9100 through usb connection.

In another PC (PC2), in the same room, I used an SDR RTL2832 to receive the packet. There is variation in the waterfall of the SDR and even in the soundmodem installed in PC2. But the soundmodem in PC2 doesn’t succeed to decode the packet from PC1.

There is something missing or what can be the problem?

I need to check the packets that it is sent correctly before sent it to a cubesat.

Thank you.

Kind regards

Kais
