€  You might do well to try the experiment, Jon.  Who knows, you could be 
right?  Wanna make a side bet of a large pizza with five toppings and 
salad bar?.

€ I am aware of no textbook that says moving an SWR meter along a 
mismatched transmission line will make no difference in the reading.  The 
93-ohm halfwave line in the Quiz was just such a case.  The measured SWR 
varied all over the place.
