Anymore updates on these units from some locals that have them? I don't read radio reference and am curious to learn more.
I can tell you that the performance on Simulcast Trunking is VASTLY superior to any other scanners I have used previously including the Uniden BCD396XT, Uniden BCD996XT and the Whistler TRX-2. I had great difficulty picking up the RISCON statewide system in Rhode Island from my home in Fall River, MA. The only zone I could get reliably (most of the time) was the Providence zone even though I had very good signal strengths on the control channels for the South and North zones. I have an excellent Antenna Specialists MON731 roof-mounted antenna and I am located at a good elevation but that didn't help (actually made matters worse at times). I could get the South zone (sometimes) if I put a Radio Shack 800 MHz antenna on the scanner's BNC connector and moved the scanner around my house until I found a "sweet spot." North zone reception was very rare no matter what I tried.
In contrast the SDS100 is receiving all 3 RISCON zones with excellent digital decode while sitting on top of my desktop computer's case and with just the Uniden stock antenna that came with the scanner. Once in a while I will get some digital "garble" but typically when I hear that I also hear the dispatcher say "please repeat" because they got the same digital garble that I received. As far as Simulcast performance is concerned I find the SDS100 to be an outstanding and excellent performer.
As with any brand-new product early-adopters can expect some growing pains and the SDS100 is no exception. One issue that has come up is that the supplied battery that comes with these initial-release units only lasts about 5 hours. Uniden realized that shortcoming during production but didn't want to hold up the release of the new scanner to its customers. What they have done for a fix is to produce a higher capacity Lithium battery that will last 8 hours instead of 5 and it is expected to be out around August (thereabouts). The nice thing is that they are going to send that new battery (and the larger battery door cover) for FREE to all of the early-adopters of the scanner. You also get to keep the original battery and original battery door cover thus giving you 2 batteries. IMHO that is an incentive to buy the scanner right now.
This new SDS100 scanner has a lot of processing power and thus draws a lot of current which produces heat. Charging the Lithium battery in the scanner while the scanner is on produces some additional heat. I have found the scanner case to get warm at times but not hot. One poster on Radio Reference used an infrared thermometer to check case temperatures at various spots on the SDS100 and found one spot on the case to measure 125 degrees. I believe that was while the battery was being charged and the scanner was on. It is unknown if heat will be a problem with the long-term reliability of the scanner. It has been posted on RR that an external battery charger is expected for the SDS100 in the future (perhaps with the release of the new/larger battery?).
Because this scanner is "water-resistant" the SMA antenna connector is not "standard." To make the radio water-resistant the SMA antenna connector has a plastic collar around it (along with an O-ring on the stock antenna) which is designed to help keep water out of the radio chassis. Because of this design parameter multiple users on Radio Reference have reported that standard SMA antennas will not "fit" or "fully seat" on the SDS100's antenna connector. I have personally not encountered that problem because I have only used the stock antenna thus far. The scanner also comes with an SMA-to-BNC adapter so that you can use a BNC antenna (like the Radio Shack/Remtronix 800 MHz antenna or an external mobile or rooftop antenna) with the SDS100.
Because this scanner is brand-new (just started shipping to retail customers the first week of June) a custom carrying case for the SDS100 is not currently available from either Uniden or any other aftermarket source. Scanner Master has stated that they are waiting for the release of the new larger battery/battery door and then will have the SDS100 measured/fitted in order to have carrying cases manufactured by their case supplier. In the meantime you will have to be careful with your SDS100 if you take it out and about with no carrying case to protect it from scratches, scrapes and potential falls.
I have no regrets about buying this radio as an early adopter as I mainly purchased it for Simulcast reception and it has exceeded my expectations in that regard. Contrary to popular belief the SDS100 is still currently available from various retailers as I type this review but they are in tight supply. If you want one the lowest price is $649.99 as that is the lowest retail selling price currently being allowed by Uniden. (FYI the MSRP is $699.99.)
