I just recently got the SDS100 a few days ago. I have had my BDC396T for a few years. I put them side-by-side and tuned into a local LAPD dispatch channel (conventional P25) and put the channel in hold mode, using stock antennas on both and both set to 2 on the squelch. My 396 would pick up the transmission first, then a second later the SDS would pick it up; then sometimes the 396 would drop off the last second and the SDS would keep going until the end. This happened with almost every transmission. Both of them would drop the transmission occasionally, but at different times. Overall, the 396 picked up and held on to a call for more of a single transmission than the SDS did. I tried this on other LAPD dispatch channels with the same results. I was hoping for more out of the SDS and am somewhat disappointed in this.
