Hi,
You can use UUCP to integrate the email stack to HF. Gnuradio I think
better be used for the layer 0 in the network stack. This is what I
wrote to integrate UUCP to any HF tnc (ardop and Vara supported for now):

Thank you all people.
We'll study more about the topic and decide which solution gives us better
results / cleaner signal.
I was asking for UHD compatibility as the software we use to broadcast DRM
(Spark) is compatible with UHD.

On Tuesday 02 June 2015 17:
Thanks Matt!
But the B200 frequency range is 70 MHz - 6GHz, so it does not cover the SW band.
I have an USRP 1 and some daughterboards, but I was thinking about something
even more affordable, that could work with UHD. Something closer to what hams
use
for SW.
