The receiver chip in SDS100 and RTL-SDR are more or less of the same performance. The difference are that with the SDS100 you get the computer, display and keyboard in one little neat unit and a much easier to handle user interface than DSD, FMP, or whatever you use, where you can avoid systems and channels with ease and change scanning groups and favorite lists and have a huge database to choose from. But receive wise a $10 SDR dongle are pretty much equal to a SDS100's receiver.I just expected more from a digital SDR scanner. My RTLSDR dongles that I bought from FlightAware pick up Airband with the same clarity as the SDS100.
Does your side-by-side comparison have both systems (BCT15x and SDS200) on the same external antenna at the exact same time? I'm wondering how you configured your test. My experience with the BCD536 and the SDS radios show that their internal antennas are horrible.Side by Side with all parameters equal my BCT15x receives much better than my SDS200 on VHF Air, Mil Air, Mil/Fed Ground VHF-UHF, and local UHF. I use my SDS200 for 800-900mhz Trunking ONLY (Simulcast) and my BCT15x for Conventional. My BCD996P2's I use for 800-900mhz trunking non-simulcast systems and have not tried conventional on those up against the SDS200.
Same Parameters, off of the same attic VHF/UHF Antenna, etc. Internal antennas were not used.Does your side-by-side comparison have both systems (BCT15x and SDS200) on the same external antenna at the exact same time?

The testing I've done using a discone and Stridsberg multicoupler shows that the SDS radios keep up with the HomePatrol and x36 models. in the aircraft bands I haven't tested against a 996 though.
For what it's worth, my SDS200 performance on analog has dramatically improved with a better antenna. Especially in my area which is not the best topography for scanning.It's like the "great on digital but poor on analog" thing. Often repeated, but not founded in fact. I've done head-to-head tests between the SDS100 and the 436 connected to a common antenna so they are getting the same signal, and there was little or no difference scanning the same airband channels.
