To answer your question, WLAC also has a strong night signal, which makes it puzzling why they simulcast sports programming on their FM sister station (the classic rocker) as well. I think they are going for "visibility" here, as AM is not "cool" anymore.
There are probably two reasons for the sports simulcast. First, it likely produces more revenue. Second, the signal on 1510 is vastly inferior to any of the full power FMs in the market... the 5 mv/m coverage of WLAC (in metros, very little listenening is done even at the extremes of the 5 mv/m... most is in the 10 mv/m) is 800,000 persons, while the 60 dbu of WSIX is 1.5 million, almost double.
The problem with AM in most metros, as illustrated by WLAC, is that the bad signals do not cover the whole metro, which in the case of Nashville is now 8 counties.
WLAC can supposedly be heard in about 38 states at night, covering about 2/3 of the country, so a weak signal would not be an issue here.
The night coverage significantly reduces the local populaton covered as WLAC is severely directional. WLAC never covered 38 states... maybe 10 or 12 with a decent night coverage before the band became more noisy and full of high powered stations in other nations that interfere with it. With 50 kw stations in Boston and Spokane on 1510, as well as 1520 in Oklahoma and Buffalo and 1500 in Wahington DC, most of the useful night signal of WLAC is KY, TN, AL, GA, NC, SC, GA and a bit of VA.
Some guys on local message boards here have complained about the poor signal offered by the AM sports talker (AM 560 in the referenced thread above), and they have a point, but I still lament the sports talkers taking away the music choices from us on our FM stations.
AM is slowly dying, forcing the formats that work on AM to move to FM. Eventually, AM will be niche and religious and ethnic, as, increasingly, listening to the band is with folks over 55 who are not targeted by major advertisers. Yet when news and talk stations move to FM, as 50 kw WTOP in DC did, they grow in the 35-54 age group advertisers love... so expect more of this.
Amazingly, in 1970 the fight for #1 in Nashville was between WMAK in 1300 and WKDA in 1240... today, 1240 does not show in the ratings, and 1300 has a 0.6 share. In fact, the sum of all the AMs in Nashville is less than the share of the #1 FM, Urban WUBT. WSM is 14th in the ratings, very old demograqphically, and also bills about 15th in the market. Pretty much dead, to say the least.
