[arm-allstar] config for split rx/tx

thanks Dave and Doug for your input - appreciated.
They are defined statically on our local 44 net and are private. At some
point we would most likely link them into allstar in general for public
access - but we're still working on a few things.
I did initially configure them as duplex - but thinking about it, wondering
if it would be best to configure them as simplex as that's really what they
are on a node basis. Where they are located will have plenty of bandwidth
on our private ham net, but if I do move it to simplex that should reduce
the data required.
While i did get them powered up etc (at least from all indications I can
see) - i have to chat with our fellow guys to debug some connection
items. I do have it defined as simpleusb but am having issues verifying
the RF setup and link with the USB fob. Can't quite get it to talk 100%.
There is some RF noise coming out. It does recognize the usb as
functional, but there may be a connection issue with the radio - will see.
Once I get this stuff connected, I'll want to install a node-less hub on a
local hosted data server that has an unlimited 20Gbps bandwidth - combine
that with our ham-friendly provider, makes working on ham projects easier.
73, Dan ve4drk
