I have a Uniden BC296D. I mainly monitor 800 mhz systems. I have found that I can set the DCS or CTCSS Squelch mode, but I don't have a clue as to which one to set it on. Does it come from the radio system that I listen to or how can I find out what to set it on. Also looking for a rubber duck antenna that will bring in the weaker signals better. I have a tuned antenna to the frequencies common in my area, as well as a radio shack 800mhz antenna. I can pick up in some areas of the house better than others, but looking for one that may do better if there is such a thing. Thanks for all help in advance.
