Yes, that was our thought with selecting the 6M band also, and using monster 6M verticals. We'd likely use beams and the 222 MHz band for the back-haul (connecting the 6M nodes). But we haven't gotten that far yet. Remember, this is just an experiment, not a regular operation (HI). 73, John - K8OCL >From: "Danny Douglas" <[EMAIL PROTECTED]> >Reply-To: [email protected] >To: <[email protected]> >Subject: Re: [digitalradio] 3kHz or 500Hz Re: Updates on effect of FCC R&O >Date: Tue, 24 Oct 2006 19:29:52 -0400 > >What does IM mean?
