[aprssig] Interesting Findings - 300 Baud AX.25 on VHF-FM APRS

I knew that but didn't consider it a problem since I typically like to use
other audio options. I have an USB Behringer device for one project and
cheap single channel USB devices for others.

Best regards,

Just discovered a show-stopper on the Kangaroo vs my Winbook:


The Kangaroo HAS NO AUDIO I/O except for audio-out on the HDMI port.  The 
complete lack of analog audio in/out rules out using software TNCs like 
Direwolf or the UZ7HO Soundmodem.

(Unless of course, you want to use one of the USB ports for an external
sound 
system or Signalink.)
