Dear LF Group,

Well, I think this is a positive development - the only minor disappointmen= t is the reduction in maximum ERP to about 3W.

As for the choice of frequency, the maritime people have a plan for a sort = of =A0"super Navtex" using OFDM modulation with a bandwidth of 10= kHz centred on 500kHz. It may be that this is just a pipe dream, and/or a w= ay to justify continued primary user status at 500kHz. But if it ever does = come into existence, it will certainly be using vastly higher powers than a= mateur stations, and the noise sidebands will extend well beyond the actual= signal bandwidth due to "spectral re-growth" in the TX PA. So it= will be good to have a significant difference in frequency between ourselv= es and the noisy things. I expect all those REAL amateurs will manage to re= duce their TX frequency by 5 percent somehow ;-)
