I am on the fence about buying the SDS200. I find nothing in the programing apps, owners manuals etc that deal with locking out unwanted PL codes (CTCSS/DCS). A channel that I listen to often does not use a PL code. So I often get unwanted transmissions from a frequency that does use PL. With my current scanners I am able to lock out the offending transmission. Maybe I missed something, can I do that on the SDS200?
