Narrative:

An aircraft called on the ground frequency. I heard only static. I asked if the aircraft calling on ground is at FBO; then taxi to runway 24 at taxiway H4. I then observed a C550 taxi to taxiway H and identified the aircraft. This is a long standing problem with all of the tower frequencys at this ramp. Several unsatisfactory condition reports and NASA reports have already been filed.
