This thread I began upon received my new SDS200 is evolving a little, as I encounter other issues that confound me!
Earlier, I followed the recommendation by some here to change the CTCSS settings on my Favorite lists from Radio Reference's pre-entered tones, to "Search Mode." My reason for this was that it seemed like certain LE dept. channels were way too quiet, when I knew they should be busier. Also, when I rotated the squelch control to "0", i.e. fully open, scanning wouldn't stop, but would continue until it landed on a single channel - the same one every time, 173.30. Search mode worked, in the sense that the manual squelch interrupted scanning instantly, and I was hearing more traffic.
Now, with all frequencies set to Search Mode, a problem has emerged with my main Sheriff Dispatch frequency, 152.72 It is the most important channel for me, and a busy one too. A loud audio distortion - tone and static- "overlays" and renders unintelligible the dispatcher's voice for the initial part of her transmission. It clears up after maybe 4 to 8 seconds. I don't hear the same distortion from my Kenwood 2 meter TM-V71A radio here in my office.
Occasionally, the scanner also stops on the Dispatch channel for maybe a second and plays a staccato, "machine-gun" burst of static - also unprecedented.
So, I am guessing the subaudible tone from the Sheriff Dispatch is getting detected by Search Mode, and somehow the search mode's processing is interfering with the audio for a brief time???
Is this a known issue? I am thinking about manually entering the CTCSS tone just for this channel to see if it alleviates it.
Thanks all once again, KM6U
