[Fists] QSY'ing away from a calling freq.

[kc9brz]

What's the protocol for QSY'ing away from a calling freq?

Say I'm calling CQ on 14.058, and I've already checked to
see that 14.060 is quiet/free (at least as heard from my 
location.)

Suppose someone answers my CQ on 14.058, and I suggest 
"Can U QSY up 2KHZ?"

14.060 might not be free for the other guy.

Do I wait for him to check 14.060 and then come back
down to 14.058 and tell me it's okay to QSY?

What's the generally understood way of doing that, and
the shorthand way of saying it?

How many alternate freqs should I check out to see if 
they are free, before calling CQ on a calling freq?

And is 500 Hz pretty much the standard for signal
separation in CW ?

Thanks.
