[grc] [Stubblefield] Simulcast DRM / Analogue

[Michelle Bradley]

For those of us who are pushing alternate spectrum for community radio, 
receiver penetration is a challenge.  REC has spoken in the past about 
opening spectrum in 11 meter shortwave band and adjacent broadcast 
auxiliary band (around 26 MHz) for lower-powered niche broadcasting.  In 
the past as analog but can also be DRM.  While there is not a huge 
penetration of receivers on the market, at least the receivers are being 
manufactured.  11m for DRM has been tested and is currently in use in 
Germany and the Vatican.

Of course, REC supports the reassignment of channel 6 (82~88 MHz) and 
potentially channel 5 (76~82 MHz) TV spectrum for expansion of the FM 
broadcast band to accommodate AM migration and potential community 
radio.  Analog receivers for this band are currently being manufactured 
as this is the FM broadcast band in Japan. Unfortunately, the next 
generation ATSC digital television standard seems to favor VHF over UHF 
so this may be a tough sell.

If you're interested in actually broadcasting to more than a handful of experimenters. At least there are 40 million HD radios in cars out there. Not many compared to the national population, but about 39.99 million more than DRM receivers.
