Roy:
No, there is no way that I know of to get the UT102 chip to read the SWR
with the IC718. I wish it did, though. I solve the problem by using an old
MFJ versatuner and an SWR meter, in line with an audible tuning aid, and
approximate the lowest reverse SWR via reflected power.
Hope this helps a little.
