    Thanks Mike, these videos really help us get the most from our Flex radios. NM9P also did a set of videos on this topic. He goes into some good detail, and I recommend them highly. 73, Len, KD0RC

    Let me see what I can do.  

    However, the process is exactly the same and the antenna selection Icons are very similar.

    Essentially:

    • Set up 2 slices on the same frequency and same mode on a clear frequency -- I usually 10 meters
    • On one Slice, select that as TX and reduce your RF power to 1 or 2 watts into a dummy load or resonant antenna
    • On the other, receiving slice, set your volume and an RX antenna (blue) of XVTR or RXA or B -- what is key is that it is a different antenna than your TX Slice antenna
    • Turn on FDX 
    • Now, when you transmit, you will be able to hear yourself in the other receiver.
    This picture covers the critical settings.   In this case, we are transmitting on ANT1 (Red) on Slice A and receiving on Slice B on XVTA (Blue) and then turn FDX on.
