We have recently had DIRECTV service installed,with two H20 receivers and the AT9 dish.I have just finished a scan of the local off-air channels with the H20 and wanted to list what the receivers are showing for this area.The channels marked with an (*) are the channels that we are currently receiving via OTA with the receiver.The rest of the channels are not locking on to a signal......... 1.WKRN-DT 2-1 Nashville,TN ABC* 2.WKRN-DT2 2-2 Nashville,TN ABC/24 Hr.
