1610 is a marginal frequency in my area. Valley Forge National Park runs an info station that covers a radius of about 5 miles. I’m right on the fringe. Also, the PA Turnpike operates a traffic alert station on 1620 or 1630 (I forget which) that is a factor here. I have found that 1580 is relatively clear in this area and is better than 1610.
Frequencies above 1610 are relatively undesireable because many radios don’t tune higher than 1610. The expanded band was authorized back in the ’80s, but it took a long time for manufacturers to catch on. There are still many car radios and digitally tuned radios in use that don’t go above 1610. I assume all of the new ones do.
