No, an interesting diversion that has been resolved. Time to return
to the real issue.

as far as cheap swr meters, the daiwa, swan, and mfj manuals all require 50
ohm coax 'for accurate readings'... a joke by any standard of measurement
for that type of instrument. but just to put this one to rest quickly... i
set up my tdr and ran some quick measurements. this tdr will resolve a 6"
75 ohm jumper in the 25' or so of 50 ohm test cable that i used. i measured
an mfj-815b and a daiwa ns-660pa and they are indistiguishable from the 50
ohm line. so the answer is yes, they do internally look like a 50 ohm line
section.

Try it with 75 ohm coax. I suspect they will be equally indistinguishable
from 75 ohm line.
