Re: [Swlfest] OT?: Digital radio HD

[Mark Phillips <g7ltt@xxxxxxxxx>]

Erm,  the digital transmission of which you speak are not near XM and 
Sirius. HD radio is otherwise known as IBOC (as those that attended my 
forum last year will know)

IBOC/HD radio is a simultaneous broadcast on the same carrier as the 
regular station. In other words, if the radio stations analogue output 
is 97.5MHz FM then the HD output is there also.  There is no spearate HD 
band.

Would this be the right time to start trashing IBOC (It Buggers Other 
Channels)?

For those that are interested, XM and Sirius transmit about 50 watts in 
the 2.2-2.4GHz range.
