I would recommend setting it up in a tabular form (makes it easier to import using Excel or other apps). See

One additional thought-provoker on how to handle the two prevailing scanning paradigms:
1) I want to hear everything possible within range of where I am.
2) I want to only hear transmissions relevant to where I am right now.
Case 1 is user-centric, i.e. draw a circle 50-miles wide centered on
me and scan everything inside the circle. This is the "big ear" paradigm.
Case 2 is system-centric, i.e. monitor only if I am within the operating perimeter of the system. For example, if I am in Arlington, don't scan Fort Worth, Irving, Dallas, Grand Prairie, etc, even though they are receivable...they aren't relevant. For example, see the coverage area I created for Arlington:
Green circles are West Patrol and comprise the "sites" in one system whose channels only include the West Patrol and FD/EMS citywide channels. Purple and Blue are similar systems set up for East and North, respectively. Takes a lot of small circles to approximate the shape of a tall, skinny area.
Case 1 could be handled by simply drawing a 50-mile circle around every antenna site (50 miles is about the maximum practical limit for 95% of all antenna sites) and scan if you are within the "big ear" circle. But, to handle Case 2, you'd also need the smaller (and sometimes multiple) circles to approximate the "logical" coverage of the system.
I'm not presenting any answers, here, I know. But I feel it my duty to occasionally provoke thought and discussion. :twisted:
