Edited sentence: Adding HD Radio technology reduces the amount of power available for the analog portion to 99%, to make room for the 1% level digital broadcast.Although broadcast translators are prohibited from originating their own programming, the FCC has allowed stations to ignore this by having their programming simulcast on an HD Radio channel of the primary station the translator is assigned to.However the boosted digital HD signal coverage would then exceed analog coverage, with 17% more population covered.In either mode, HD Radio may be passed along from the main station via a "bent pipe" setup, where the translator simply makes a frequency shift of the entire channel, often with an intermediate frequency.NPR Labs recently did a study of predicted HD radio operation if power levels were increased to 10% of maximum power, and found the digital signal would increase RF interference on FM.The majority of translators fall into this catagory.Translators are not required to pass-through HD Radio at all.Translators which use a separate receiver and transmitter also require a separate HD Radio transmitter, just as the main station.de:HD Radio
