Yeah, but Riverside is in KTNQ's null - where their day pattern has the
equivalent of about 6kW, NOT 50kW. The KTNQ day pattern runs 6kW or less
over most of the ESE quadrant. They have far less toward Riverside at night.
And Riverside is in the max of 1050's day pattern.

Presumably the 1020 IBOC pattern is proportional to the main signal's
pattern.


I wouldn't presume that. Most ATUs and phasors are designed for the carrier
frequency. The fact that a transmitter may also transmit audio sidebands is a
secondary issue. IBOC splatter was certainly not taken into consideration in
the design of nearly, if not all, of the phasors in use today.
