Phasing in and Increase of the Digital Signal over
Time would ease the Transition to HD Radio.
First Year 1% Digital
Second Year 2% Digital
Third Year 4% Digital
Fourth Year 8% Digital
Fifth Year 16% Digital
A 16% Digital Signal should give a HD Radio
Station a Signal Coverage Area far better then
their present Analog Signal Coverage Area.


Based on actually working with 40 or so HD stations, the current HD
signal, on AM, covers to at least the same usable and used coverage area
the analog signal reaches, sometimes more. On FM, it also reaches the same
area where nearly all actual listening happens.


There you go again saying that only those inside your precious city grade
contours count as listeners. Probably 40-50 million people in the US would
beg to differ.- Hide quoted text -

BAD,

Clearly this Thread is positive proof that the 'magical'
10mv/m Contour does not serve this Rural Area of the
State of California very well -and- a Blinking Blue Light
says that the Digital Signal is not strong enough to
effectively reach the same areas where an Analog
Signal seems to make it in fairly well - be it AM or FM.

Again a gradual increase in the Digital Signal Level
from one year to the next would have all areas served
and produce a steady transistion from Analog to Digital
as new HD Radio Listeners and Equipment replaces the
old Analog Radio Listeners and Equipment.

* Digital Output Power Level wrt Analog ERP
First Year 1% Digital
Second Year 2% Digital
Third Year 4% Digital
Fourth Year 8% Digital
Fifth Year 16% Digital

* Analog Output Power Level Reduction
Sixth Year -10% Analog
Seventh Year -20% Analog
Eighth Year -30% Analog
Ninth Year -40% Analog
Tenth Year -50% Analog

What HD Radio will do for AM/MW Radio is debatable.

What HD Radio will do for FM Radio can be clearly heard.

imho -de- hd radio needs more power output to serve
the whole country which includes rural areas
-or- will rural areas be forced to pay for XM or Sirius
Satellite Radio to get digital quality sound ? ? ? ~ RHF
