Sorry John.

Dave is right. You are incorrect.

Contractions are formed as 's: He Is = he's.

Posessives are likewise formed as 's: Heil's contacts all used CW.

Plural possessives are formed as s': Heil's contacts' radios were set
to CW mode.

Don't sweat it.

Amateurs (plural, and NO apostrophe) frequently attempt to argue the
incorrect to be correct, and so look imbecilic.

In this instance, one anonymous fellow--maybe a radio amateur and maybe
not--has attempted to do what you describe. I wouldn't call him an
imbecile, just unschooled.

Part of the new amateur policy should be to attempt to correct this
image. The image of the unwashed, illiterate ham needs to go ... I tire
of the smirks-behind-the-back given by professionals.

I don't know that there is such an image. You could do your part to
better things though. You might use the internet to undergo a crash
course in the use of the apostrophe.
