Re: [IRCA] Good night last night, and going for 400 stations

I'd not expect skip IBOC to be able to bother freq's 20 KHz away if you have a decent rx, which your SDR certainly is. Now if you're driving around in a typical cx rx, that could be a different story.

The main and brutal IBOC hash occurs from +/- about 10 to 14 KHz away from the offender's freq. This means that KSL's IBOC should be awful from 1146-1150 and from 1170 to 1174. (Yes on good skip nights it can bother me here over 1200 miles away (still 1 hop in winter cx)). 

So how should we best listen to 1150 to get less IBOC trash from KSL? USB..yes upper sideband! This will take out considerably more IBOC than listening in LSB will. Of course if KSL is strong enough to severely slop 1150, then you have issues in USB and an unworkable situation. How should we best listen to 1140? LSB of course! This should render anything on 1146 as no factor. IBOC should only be a problem on 1140 LSB if you live in close groundwave range to KSL.

ie here I am 14 miles from WBBM and 19 from WSCR and their IBOC's do mess up channels +/- 20 KHz away, but these are 50 kW ND over conductive midwest ground. Using the proper sideband to get further away from the IBOC helps.
