Please take a quick look at this.

Is anyone else thinking a very useful adjunct  would be a reliable  (RasPi ?)  interface to one of these?

… even if we have to build a bi-directional store and forward capability to accommodate the huge discrepancy in throughput?

I suppose a Flex Radio 6300 series offers similar utility.  Unknown which exposes more easily accessed APIs

An automated interface to HF for any kind of data.

If I correctly understand this brochure and Barrett NVIS radio systems in general, the radio will perform data transport via it's 'Break Out Box' Ethernet interface.  Prior Barretts would perform data transfers from a serially or USB connected Computer.

Should we expect dtd to work or be useful for file transfers over an NVIS, or series of NVIS hops without needing to buffer most of any given message or file?     Not for use within an Amateur MESH,  rather a potentially unattended interface at a boundary to a Served Agency  or NGO system utilizing these.  

I'm not  the person to address this further,  I'm  just asking *if*, would it,  but not hypothetically.

Does this help?

Not as a DtD device...

This HF radio likely be able to leverage the AREDN-based network as an IP device over an Inter/intranet where you are the user of the NVIS client application.  But not as a DtD device.  Think of the DtD interface as just another RF mesh link (i.e., regular Ethernet data stream plus the OLSR routing protocol).  The NVIS radio wouldn't know what to do with the OLSR protocol.

Dropping DtD from the concept changes the topology, it will

still be the same result.  

Extending AREDN's reach where/when useful via an NVIS Network may have immense appeal in some EmComm circles.  'NVIS Network' is the Barrett part of the picture.  There may be others but I haven't come across them yet.

Ken's comment, as usual,  is correct - is there some way to move this thread to a more appropriate Forum?
