Here's the update...I live in the vicinity of the Route 63 and 67 junction. The driveway is 1.3 miles from the aforesaid junction. Driveway: No HPD signal. Onto Route 67: No signal. Onto Route 63 (towards New Haven: No signal). Reaching the intersection of 63 and Downs Road (one mile from the 63/67 intersection): Bingo, HPD is received fairly loud and clear, but not 5x5. From there I traveled down Downs Road onto Route 69 and then took the side roads through Bethany to ultimately come on to Shepard Ave., Hamden. From Shepard onto Whitney Ave. towards Cheshire, the HPD signal was lost and/or very scratchy by the time I reached Cook Hill Road, Cheshire
I think that either there is a transmitter/repeater issue or there is an antenna issue (base and/repeater site).
In conclusion, I have never encountered a weak signal from Radio Free Hamden in the past!
