I'm still waiting for someone to give me a convincing reason why we continue
to test element 1a.

o the old fuddy duddies say so
o the FCC makes no money from dropping the requirement
o "I had to, so you have to!"
o no good reason whatsoever
o the FCC is busy selling spectrum, so if HF is actually used, they can't sell it
o too busy with killing the HF spectrum with BPL
o too lazy to act because Powell sapped all their inhibition
o no good reason whatsoever (oh, I said that)
