Now that the lazy days of summer are upon us, any of you scanner listeners may want to add a local notification network repeater to your channel banks. Tac-7 (http://www.tac7radio.com/) is now using the 462.650/467.650 PL=146.2 for broadcasting notifications. Listening in is free, joining requires a GMRS license. This was sent to me so I don't know which is input or output. Dan KA1RDZ
