I now work in a large mfg plant in southern Ontario. I have tried to bring in my ws1080 at night to help kill some time. It works well at home but in the plant it receives nothing, not even in plant radio. Is there a filter I can get to cut out the excess noise? I am using the stock antenna. I am trying to receive Fleetnet, Windsor Fire, Detroit Fire & EMS. I also have access to a bcd436 but because I got the ws1080 cheap I prefer to bring that in.
