I did some checking at radio-locator.com to see the coverage of these three new stations.
WNEV-FM is a Class A signal and covers West Helena and Clarksdale, MS with a city grade signal.
KAJK-FM is a Class A signal and covers Mariana, Marvell and Forest City with a city grade signal.
KCLT-FM is a Class A signal and covers Marvell and West Helena with a city grade signal.
A Class A FM is not the most powerful. The most powerful FM stations are Class C stations and they cover large areas...like 100 miles or more in all directions.
I think a Class A covers somewhere around 10 to 20 miles with a city grade signal (meaning you can hear the station on a radio located in a concrete building).
It is nice to add more stations but...these stations basically serve the area already covered by WREC. If you look at the nighttime coverage of WREC, the coverage void exists north of Memphis not in those area. I have put a link to WREC's nighttime coverage. So, at sunset, we lose coverage in most of the area north of Memphis Having stations in Covington and Jackson helps but the void is in the area around Dyersburg and as far south as Tupelo.

If you have some time to kill, you can search each of the stations on the network on this site and see their daytime and nighttime signals. FM's have the same signal day and night whereas most AM's have to reduce power at night.
I looked at the WJAK night time signal and it is not doing much except covering Jackson.
