Looks like everything is working correctly. I see your packets are making it to the APRS-IS:

I have Direwolf decoding FalconSat-3 

+ Diamond x200
+ LDF4-50
+ Airspy Mini
+ VB Audio Cable
+ Direwolf 9600

But I don’t see these making it to the APRS-IS

Reading config file direwolf.conf
Available audio input devices for receive (*=selected):
    0: CABLE Output (VB-Audio Virtual
    1: Microphone (Realtek High Defini
Available audio output devices for transmit (*=selected):
    0: Speakers (Realtek High Definiti
    1: CABLE Input (VB-Audio Virtual C
Channel 0: 9600 baud, K9NG/G3RUH, +, 44100 sample rate x 2.
The ratio of audio samples per sec (44100) to data rate in baud (9600) is 4.6 This is on the low side for best performance.  Can you use a higher sample rate?
