I've been investigating the use of filters on my SDS200 & 100 and have a couple of questions...
I live in west central Florida and when monitoring my local county (Pasco) I have an RSSI that fluctuates between 75-90 dBm with good clear reception. Scanning the nest county up (Hillsborough) on both their EDACS and P-25 I get a reading varying from 102-106 dBm with rather scratchy reception. Distance to the antenna for the next county appx 25 miles. After switching through the filters i find only minimal difference in both RSSI and audio. I'm running a Yagi antenna mounted 35' up aimed directly at the transmitter with 65' of LMR 400 coax lead in. Is the reception that I am getting considered reasonable or are there other things that I should look at to improve? What RSSI should I reasonably expect? I have the modulation set to FM on both systems.
I defer to y'all who have more experience than I and appreciate all input.
Thanks
Mac
