Boston FM HD Coverage

Just asked an engineer friend at VT Public Radio and he says IBOC FM HD is 
20db down from the main signal, but that there is a pr0posal to raise it 
to -10db.

So, for example,  a 20,000 watt main FM analog signal the FM HD is 200 
watts. In the same example the proposal would raise it to 2000 watts.

Even a 200 watt signal from the Pru or 128 towers isn't bad.

I don't know if the AM specs are same, but if they are, a similar 200 watt 
signal on HD AM , in a market like Boston, would not have nearly the same 
impact as the HD FM example
