    "content": "Hi Roger and the -bb,\n>From memory it takes up less than 12.5 kHz which is the\nchannel spacing on 2 meters (In Region 1 at least).\nFrequency deviation like 2.5 kHz (old 3.5 kHz and even some\nhave 5 kHz deviation).\nIt is the frequency deviation that is a the issue with SO-67 (I think).\nIf you run too high deviation on the uplink the LF to the transmitter will\nmake it deviate too much. Even for a normal (old) setting on the receive\nside.\n\nThe Carson rule says: Signal Bandwidth = 2 times (Deviation + modulation\nfrequency).\n\nDid that help ?\n73 OZ1MY\nIb\n----- Original Message ----- \nFrom: \"Roger Kolakowski\" <[email protected]>\nTo: \"OZ1MY\" <[email protected]>; \"Kostas Ioannidis\"\n<[email protected]>; \"AMSAT-BB\" <[email protected]>\nSent: Saturday, November 07, 2009 3:03 PM\nSubject: Re: [amsat-bb] Re: SO-67 over Europe thanks for test\n\n\n> How \"narrow\" is FMN?\n>\n> Roger\n> WA1KAT\n>\n> ----- Original Message -----\n> From: \"OZ1MY\" <[email protected]>\n> To: \"Kostas Ioannidis\" <[email protected]>; \"AMSAT-BB\"\n> <[email protected]>\n> Sent: Saturday, November 07, 2009 6:40 AM\n> Subject: [amsat-bb] Re: SO-67 over Europe thanks for test\n>\n>\n> > Hi Kostas,\n> > If you do not have FMN on your radio, turn the mike gain down and/or\n> > do not shout :-)\n> > 73 OZ1MY\n> > Ib\n> > ----- Original Message -----\n> > From: \"Kostas Ioannidis\" <[email protected]>\n> > To: \"OZ1MY\" <[email protected]>\n> > Sent: Saturday, November 07, 2009 12:20 PM\n> > Subject: Re: [amsat-bb] SO-67 over Europe thanks for test\n> >\n> >\n> > > Goodmorning,\n> > > As the previous operator said thank you a lot for this great sounding\n> > > sat!
