Atlanta Center Update (High Altitude)

[AirScan]

I was passing through Atlanta Center airspace a few days ago and noticed they had swapped the high altitude sector 42 and 43 frequencies.

Sector 42, Salem High (FL300 to FL340) was using 132.975

Sector 43, Pulaski High (FL240 to FL290) was using 120.725

In the past these two frequencies have been used in reverse, as listed in the database.

Atlanta (ZTL) Air Route Traffic Control Center (ARTCC) Scanner Frequencies and Radio Frequency Reference

Maybe it was a temporary change ? Can anyone in that area (northeast part of Atlanta Center bordering Washington and Indianapolis) confirm the frequencies they are using now for these two sectors ?

Upon further listening it appears they might have re-organized the airspace below FL340 in that area so that the sectors are now split laterally east/west instead of vertically at FL295 ?

Internet radio coverage of that area is poor so it's hard to tell for sure but from what I have been able to hear it sounds like they are using 120.725 in the west part of the sector and 132.975 in the east part, from FL240 to FL340 ? (see attached chart).

Again if anyone has good reception of that area and can provide more info. it would be appreciated.
