Narrative:

There is consistently poor; sometimes unreadable; communication reception below about 4;000 feet northeast of chs. The east frequency for chs is 119.3 and this problem is well known to the ATC; chs TRACON; who have requested it to be addressed several times but to no avail. The west frequency 120.7 actually works better in this northeast sector. This is not an isolated incident with just one or several aircraft but is nearly universal.it's an area of high density VFR and IFR traffic with multiple instrument approaches to several local airports and an arrival gate into chs for air carrier and military traffic. Additionally; there is an active flight school and student practice area located in this sector. It covers airspace inside and adjacent to the chs class C and has a high potential for midair collisions. Arriving and departing IFR aircraft receiving clearances need to have clear radio reception during high workload phases of flight. VFR aircraft receiving flight following also need clear communication; as well. Please address as soon as possible!
