"David Eduardo" wrote in message ... There is also some evidence that IBOC interference can affect home metro groundwave coverage of adjacent channel stations. But not much. I can listen to the 1050 in the Riverside market within 10 miles of the 1020 KTNQ 50 kw IBOC site. 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. 30 kHz spacing and 6 kW doesn't sound like a severe test to me. |
