I don't know if you have been following the digital tests going on over
The Mighty KBC, but they have gotten me to thinking of other uses for DRM. I've always felt that some transmissions on HF such as NAVTEX, SITOR, WEFAX and VOLMET could be incorporated into robust DRM transmissions instead.
Although there have been some tests (TDF sending photos and BBC's use of
Journaline) I have never seen or heard true utility broadcasts being tried or tested.
Moreover, it seems that many of these traditional services are showing their age. Recently
USCG threatened to eliminate some of their weather related HF services to which they received significant hate mail. The need is still there!
I recently read that the
German military (their equivalent to AFN) were considering DRM for ships at sea and remote military installations. Why not and perhaps
AFN might consider the same thing, as they seem to be phasing out the SSB feeders they have used for so long.
So once again, DRM offers the technology for service replacement, yet it is being largely ignored. OK, there is only
one stand-alone receiver on the market. That could change if manufacturers thought they'd have a market. Any ideas how we can encourage these entities to investigate some of these options?
