Thank you for responding to my inquiry. I already programmed all the frequencies assigned in the FCC database link you provided. None of the licensed frequencies are being utilized for the input of the 159.090mhz repeater in Weehawken. The input frequencies remains unknown to me.
Why would the OP need to try to listen to the "input" unless it is a split Duplex system? A split system has the option of not repeating the mobile, only the dispatcher hears the mobile.
You mean they were running 159.09 in simplex before this change? Interesting because I live out in West Orange and I have always heard them loud and clear.
