OK Now I will need to DX the WLW HD signal. Alreayd got 1530 from 400 miles away.

I wondered why I had lost them in Dallas during the day! Usually they are pretty easy to catch if you null KSEV Houston. But lately - nothing. IBOC must be affecting coverage somehow. I knew it did for FM - this is the first indication of trouble on AM as well.

I've noticed them weaker at night here in Philly, as well.

Heck, they're weaker here in Southern Michigan!<P ID="signature">______________

OK boys, before you go blaming IBOC, take a look at the A index the past week. It is through the roof, which means we are in near or at Aurora conditions. Therefore WLW will be weaker in areas other than ground wave.

I'll agree with that in that from here in Columbus, Ohio, WLW's signal has remained the same both day and night. But the hash is vicious even 90 miles from the tower, clearly audible from 680 over towards 720, so it has to be something else down in Cincinnati, probably giving the local 740 fit after fit.

I have heard IBOC sidebands as far as 300 to 350 miles from a station. which gives me some hope that maybe it will be possible to recover a perfect digital signal.

I've never heard an IBOC sideband more than 15KHz from carrier. The cutoff at 15KHz is awfully sharp; if an IBOC station is splattering 40KHz from carrier, there's something wrong. (probably with your radio, possibly with the station)

I'm about 350 miles from Chicago. My Receptor HD tells me that WSCR, WGN, WBBM, and WRLL *have* IBOC but so far it hasn't even decoded call letters, let alone any audio. But as has been said elsewhere, propagation is pretty bad this week; I'm hoping to have more luck when conditions come back around. WLW sure ought to make the trip too, also WCKY. (some nights WCKY is louder than WLAC here...)

I'm about 10 miles from WLW's tower and 740 still sounds fine. But the hash makes reception of WSCR and WGN impossible-although those stations were difficult to hear before. Last summer when I was in Chicago, WLW was easily receivable along Chicago's lakefront and around I-80 at high noon. I wonder if that is still the case since WSCR and WGN went IBOC.

I was listening to WLW today while in Milwaukee and WGN running HD. I am about 70 miles (??) from WGN.
