It definately blows anything else out there out of the water for simulcast reception. My BCD-436HP you had to hold it in a special spot in the room to hear a 700Mhz trunked system.The SDS-100 you can walk,run,drive and it decodes fine.

For LSM, the Unication has it beat. For features, multiple bands, display, etc etc then Uniden comes out on top.

Comparing it side by side to both a 436 and a 536 the SDS100 blows them both away.



IMHO it hears analog as well as the older models. But the p25 simulcast reception is unbelievable. With yagis and pre-amps I am hearing P25 systems up to 100 miles away. Systems that do not even show on the 436 and 536 receivers decode perfectly on the SDS100.


I like the improved display, the crispness of the audio, and the Ignore NAC feature.



I have been in it since the crystal days. IMHO the SDS100 and it's SDR architecture is a game changer.


The price is tough. But the radio is actually worth it.

Bought SDS100 couple days ago from HRO.

Like - display, ease of use, GREAT LSM!!

Dislike - stock antenna is junk, VHF/UHF interference unless you have a powerful antenna and the worst is HEAT. How bad? 113F - 116F without the battery inside (took it off to lower the heat). It gets dramatically higher if you charge while using the unit, to a point it'll just stop charging at once.

Maximum rated chip temperature for most recent CPUs (as well as the SDS100's tuner chip) is around 100C, or 212F. So while the SDS100 gets hotter than other handheld scanners during operation, it will run in a hot vehicle with the windows rolled up without any effect on performance (other than turning off battery charging) or damage.

No need to take the battery out.

What is the ambient temperature where the SDS is being operated? Mine will shut down the "charge while on" feature when the surrounding temperature gets somewhere between 85 and 90˚+. Not sure if the radio is measuring ambient temperature, chassis temperature or battery temperature to determine when to shut down charging. Not an issue for me though - mine runs 24/7, either in an a/c'd room or an a/c'd vehicle, and never shuts down charging in those conditions. And I monitor very busy systems.

Indoor, average temp 70F. My unit shuts down charge while on feature too when it gets too hot, I'll try to capture the exact temp when it happens next time and post here.

Mine is running plugged in average 18 hrs daily and no heat-related charging issues to report. Has never once shut off during or after charging. As hard as I might look, I cannot find anything negative to report. So it runs warm. My hands run cold in the winter. That will be a good combination, me thinks.

It's usually not the semiconductors that fail from high temperatures, it's the passive components like capaitors. The standard, cheap ones, are probably rated at 85C and the the more expensive ones are 105C. When the temperature starts to reach the limits the life span will reduce drasticly. Heat are never a good thing in electronics.

And as the capacitors are not mounted directly to the chip dies, an 85C-rated capacitor is more than adequate. 85C is 185F, which is far hotter than the interior case temp of the SDS100.

The SDS100 has the competition scared to death.


The competition, Whistler, is releasing an I/Q based portable AND mobile scanner as well. And while the SDS-100 is the leader as far as “scanners” go, it still does not keep up with my Unication G5 as far as LSM and distance.

It remains to be seen which will get released first, the expected but not-yet-officially announced Uniden base/mobile, or the TRX-100/200.
