Things like, Years ago what with, the big boys in radio, running the DAB sites, and pricing small stations out,
poor quality, due to cramming too many stations on the multiplexes
I remember hearing Talk sport on DAB, and the audio quality, was worse than their Medium wave AM
The actual frequencies used for DAB, are known for their Restricted range, Originally used during WW2
for Tank to Tank Comms. (some 19 Sets, had it) There are still Band 3 Comms. adjacent to the DAB band
But they are to be moved to better channels, and this will give more space for SSDAB in some areas
Band 3 Comms. was done very similar to a Cellphone system, with multiple sites linked together
So SSDAB will need multi sites in the same way, but this then increases the cost of transmission
Normal DAB uses multi sites, In Northamptonshire, 3 of the sites are under 5 miles apart,
a single freq network, a couple of these are running 300 watts, Think, If you ran that power on FM
It Would cover several counties, from one site. "Digital Economy" rubbish, it needs far more power than FM
The old 405 line TV, was on a similar Frequency band to DAB, The old Chan 1 BBC London, and Chan 9 ITV etc
but of course, it used high power, and you had a big Roof aerial for it, not a telescopic one
DAB radio Manufacturers don't seem to put Aerial sockets on DAB sets, so you could plug a roof aerial in
I saw a Kitchen DAB set in LIDL today, fixes on under a shelf, no aerial skt, just the dangly wire
Ofcom tried to create interest in SSDAB, but the government has said, with any new SSDAB multiplex
If there is a Commercial DAB covering the same area, The SSDAB coverage has to be Reduced by 40 percent
(40 % of the Population covered) So in some areas, this could be yet another Nail in SSDAB's coffin
I think SSDAB will only be worth doing in Big Cities, Rural wont be so good
So investors in SSDAB, will need deep pockets, I remember Mike Simmonds saying ages ago...
the classic comment...."SSDAB makes No Financial sense whatsoever"
They will need to be careful, if they DABLE with DAB !
As I said a long time ago, The most Important switch on a DAB Radio, is the one Labelled FM band, ho ho
