Re: LF: Re: 137 kHz band - WRC07

The Canadian proposal was based on 1W EIRP according to Jim, VE3IQ one 
of major driving forces behind it.  i May even have an email around here 
somewhere explaining the issue from many years back...  I think they may 
have intended to ask for 1W EIRP and start off by asking for 1W ERP, you 
know the old ask for more and have what you want as a concession...
