Re: RE:Why aren't FO satellites more popular



I have to admit that it was some two/three years ago but a terrestrial
survey that I did then with just a VX1 handheld and its tiny whip showed
that  2 metres was full wall to wall with intruders all around the
Philippines and Indonesian islands.

Generally it seemed to be YLs chatting and chatting and chatting

GSM was already available then but maybe it is cheaper now and the QRM could
have reduced but I somehow doubt it.

cheers all
