Tomi:
Echolink is not governed by the FCC.
The repeaters and simplex nodes in the US that you may connect to are
governed by the FCC.
So, this means you can connect on echo link to what ever node or link or
station you so desire anywhere in the world.
Since you are not actually transmitting in the US when you connect to a
repeater say in the UK operating on 70MHZ, it would naturally not fall under
FCC rule.
Remember, echolink is not precisely an on air system until it gets
retransmitted in what ever location you are connecting to.
Even if you connect through your local repeater, or simplex node using a
radio, and talk to someone in the UK on 70 megs, its still fine because the
transmission is sent out in the country where that band is legal for amateur
voice usage.

So the fcc has no say over who you choose to connect to on echolink...and
good operating practice is always in order...as well as attempting to keep
in mind the rules of what ever country you are connecting to...and mostly
all countries on echo link have similar operating rules and procedures to
north america.

And just for reference, there wouldn't be any repeaters in canada on the
portion of the 220 meg band that canada is allowed and the US isn't.
All repeaters are located in the same portion of the band that is allocated
in the US.
The only time that you run into different band parameters is when looking at
european and asian band plans...for the most part though, most european and
north american countries are rather close in their amateur band layouts.
 You might only see slight variations on how much band spread is allowed and
the frequency discrimination such as how wide you are allowed to transmit on
VFH is quite different between north america and europe.
