Re: soundmodem on OpenWRT on ASUS WL-520gU router with USB audio

[Bob Nielsen <n7xy@clearwire.net>]

Another suitable platform is the $99 Sheevaplug dev kit <http:// 
www.globalscaletechnologies.com/p-22-sheevaplug-dev-kit-us.aspx>.   
I'm running a DX Spider node on mine, but haven't yet got packet set  
up.  I'm planning to use a USB TNC, but soundmodem would be an  
option.  It comes with Ubuntu 9.04 installed but the kernel lacks AX. 
25 support so I compiled a new one but need to install it on a SD  
memory\x10 card and reconfigure a few things so it will boot from the  
card.  The Sheevaplug runs on a 1.2 GHz ARM processor and has ports  
for both USB and gigabit ethernet.  Check out the Xastir reflector  
for KM5VY's experiences with his Sheevaplug.
