The new denver international airport has a radio problem at the approach end of runway 35L. Aircraft cannot hear the tower when holding short of the runway or when holding in position on the runway (we no longer taxi anyone into position and hold because of this). The problem could be the hill just on the west side of the runway. It could be blocking the signal. Although we are able to work around this situation, it still should be corrected for safety reasons. Callback conversation with reporter revealed the following information: callback to a den ATCT procedures specialist revealed that a blind spot does still exist in that area near runway 35L. The specialist advised that airways facilities communications is working to correct the anomaly.
