Why?

Repeater directories have been around in various forms for a long time. The ARRL has published its Repeater Directory for twenty-five years. Also from ARRL, is N7JXN's North American Repeater Atlas. The Radio Amateurs of Canada's Repeater Maps and Directory is now in its fifth edition.

So, why do we need yet another book of repeaters? The best answer is another question, "Why does the AAA publish strip maps?" Thus you have VE3AYR's Interstate Highway Repeater Maps in a familiar format to tell you where the repeaters are where you are driving. As well, if you have tried other larger or smaller formats, it is time to try Interstate Highway Repeater Maps .
