The ATU is located on the PA board in the radio and, when enabled, is inline with either ANT1 or ANT2 (depending on which antenna was used for tuning). The transmitter is required to initiate the tuning algorithm in the ATU. Once the ATU has been tuned and it has been selected (ensure that the tune was successful and the ATU is not in bypass), it will also be in line with the receiver for any slices or panadapters connected to the antenna that the tune was initiated on. So the ATU does work for receive also, but only for the antenna selected when the tune was initiated.
