Bill,
Having followed your various posts, I am under the impression that you are
thinking of DX in the wrong context.
You can hear DX on any radio and any antenna. It is often more a case of being
in the right place at the right time than of 'DX' equipment.
It is also very dependent upon operator skill, in a word "patience".
Studying propagation forecasts and listening in a given frequency spectrum when
a path to said area is suspected to be operative.
The SX-42 is a fine machine and you can certainly hear DX on it. It has terrific
audio when using the intended R-42 speaker. This is also true of the SX-62.
The SX-100 is a great general coverage receiver, and arguable the best one that
Hallicrafters built. Good sensitivity and selectivity.
I personally like the SX-117 with its triple conversion and outstanding
selectivity. However, it is a Ham band, not general coverage, receiver! It so
happens that my favorite SW ban dis 31 meters. The SX-117 is crystal controlled
and has a crystal for WWV, 9.5-10.0 Mhz The 31 meter band! This RX can split a
hair and will pull weak stations out of the noise with remarkable ease and
outstanding clarity.
Bill, I know what you are trying to do, but there is no magic answer. There is
no one receiver or antenna that is better for DX than another, within reason of
course. Any good receiver will work just fine for what you want to do. All of
the receivers you have named have good sensitivity and selectivity. Beyond that,
a decent longwire antenna and/or multiple band dipole, RX only antenna tuner,
and lots and lots of patience are the recipe of choice.
Some people prefer to listen with headphones Vs a speaker, as the headphones
block out noise from your immediate environment and allow you to better hear a
weak signal. Some people can tolerate them, others can not.
If you do not have a copy, buy Chuck Dachis "Radios By Hallicrafters" Bill.
Money well spent!

I think it may have been established by Phil and others that the SX-71
may be superior to the SX 62 as a DX machine where as the SX 62 maybe
works for the SWL. How do the SX 42 and SX 100 fit into things as DX
machines, particularly sas comparred to the SX-71
