I just got my GRMS call a couple days ago, live a few miles NW of Boston, MA, have been scanning the GMRS repeaters, and not hearing much. Drove about 10 - 20 miles today, external antenna, scanned the same repeaters, and again, quiet. Is there any repeater activity in area roughly 20 miles NW of Boston (Lexington/Burlington/Woburn)? Thanks. Scott
