We all know now that the SDS100 does digtital simulcast decoding as well as the best in class.
And that's probably what people gonna use it for, a dedicated digital simulcast scanner, but can it be used as a multipurpose conventional scanner?
How does it perform in analog 30MHz, 155MHz and AM mode airband?
Reports like "I can receive a tower 30 miles away" "I can hear lots of aircrafts" is useless. You'll need to COMPARE with another receiver using similar antennas and in a similar situation. The best would be to have another scanner next to a SDS100 and perhaps have a 118-136MHz search going and nothing else or scan a single group of VHF analog frequencies.
How does it perform with CTCSS tones? Search finds it quickly? Open and closes SQ quietly without any noticeable delay?
I often find air AM mode to have a too open SQ level in scanners. It is much more noise when SQ opens compared to FM as AM mode use the same filter as FM mode and sometimes even use FM 25KHz instead of the NFM 12,5KHz filters when the optimum should be something like 6KHz for AM. I guess that SDS100 are no different and use old way of thinking and do not use super narrow SFM 6KHz filter for AM and NXDN narrow channels? Uniden have volume offset per channel/TG in some scanners but offset SQ would also be useful.
