   There really isn't a need to even specify a power limitation !
If the WRC conferees thought about it for even 1 minute they'd realize that 
it's self limiting!
Not many hams are going to put 300 meter high top loaded towers!
You quickly realize in this business that with amateur size towers or antennas 
that you very soon come up against component limitations in terms of voltage 
(short verticals) or current (loops).

If there were no limits at all the vast majority of hams would still be at the 
1 watt or less ERP level, perhaps a very few ambitious hams might reach 5 
watts, in any case not enough to cause interference to anything. 

It is foolishness on the part of the WRC conferees to split hairs between ERP 
and EIRP!

If there is a 1W EIRP ham band, I will continue to renew my Experimental 
license WD2XGJ which has a 10W ERP limit and no interference reports to date!
