Based on the block diagrams and the full duplex nature of the radio, the ATU
is only in the TX RF signal path.  It sits in between the HRFIO RF input and
the PA RF output.  If there is no ATU, there is just a coax jumper in
between the two aforementioned connectors.

Subject: [Flexradio] Flex 5000 Tuner on RX?

How does the internal antenna tuner play into the antenna switching matrix?
In particular, are there conditions where the RX signal is going through the
tuner, or is it in the TX path only?  (After installing the new HFIO board
today, I'm guessing that it's TX only, but would like to verify that.)

Thanks,

John
