As an update to my previous post about my experience with the BCD436HP here in Springfield, MO...I took the plunge and picked up a SDS-200 a couple weeks ago. WOW!
Appreciating this thread is about the performance of the BCD436HP, I won't go into just how awesome the SDS-200 is but, rather offer my experience using both over the last couple weeks.
Sitting the two units side by side, both with their stock antennas, and identical favorites lists loaded from Sentinel, there was marked improvement in what I was receiving - quality and quantity - on the SDS as compared to the 436. I'd say the 436 only pulled in about 80-90 % of the conversations the SDS did. Probably another 5% of the time, when they both locked on a channel, audio would come through on the SDS but would not on 436. It would just be dead air on the 436.
I still maintain the 436 is a really good radio but, at least based on my experience here in Springfield, it is outmatched by the SDS200 by quite a margin.
