We have a 420 MHz link path that runs from Chester PA to Ocean City NJ that
only runs 2 Watts. It works just fine. We are going to change it from 420
MHz to 927 MHz over the week end of April 4th. Not because it does not work
well but because we have Hams get on one or the outher pairs and talk
simplex. Big problem. We up graded most of our links to 1296 MHz but this
path is shakie on 1296 in the summer so we are going with 927 as there are
not many Hams there. We will report on how it makes out.
Very best of 73,
