Question about reception in Atlanta

S

smashedcd

When I was in Atlanta a long time ago the main problem with all the stations is you couldnt pick them up because they were so close together. 92.9/96.1 would jump in on just about everything and the twin country stations would do the same thing (forgot the frequencies). So how is it now with digital radios and HD? Are the airways still garbled in Midtown Atlanta? Is there problems with bleedover now? Just curious.
 
(Tom, correct me, but) Any collection of stong FM signals close together, as is the case with FM signals from the towers on Briarcliff Road, creates intermodulation distortion in the front end of FM radios, which make it difficult to pick up weaker signals.
 
You're correct, Og. That was why Katz chose to purchase the 106.7 signal to make into an Atlanta station. A halfway decent car radio would carry it down 85 all the way through town. 97.1 suffered horribly from intermod.
 
I figured it was still the same. It was so bad I had to go out of town completely to hear all the stations in Atlanta. I just wonder what the digital hash is doing to make it even worse.
 
The digital carriers aren't a problem. They're 20 dB down from the analog. Given the location of towers, there isn't much of anywhere that anyone's analog is within 5dB or less of anyone else's adjacent IBOC carrier. Even chitty radios have a capture ratio around 3/4dB or so. I don't think anyone is running the IBOC on AM currently.
