SDS150: New Uniden Scanner announcement at SEMA 2025

[jtwalker]

Does anyone know if a USB-C hub can be used with the SDS-150 to gain Ethernet capabilities?

Doubtful. Wouldn’t the host device/computer need a driver and configuration to access the network?

This is a bit off topic but curious has anyone looked at the design of Icom R15 for analog? Its Double superheterodyne. How does the R15 circuit design compare to the Uniden analog scanners, ie 160dn or BC125at?

TCP/IP would have to be supported in the SDS150.

R15 have 1:st IF of 50MHz and second of 455MHz while the 125 has first 265/380MHz 2:nd IF 21.3MHz and 3:rd 450KHz.

Did you test the SDS150’s performance during your flight? I have used all of my scanners midair and I find that being at such high altitude greatly improves reception when monitoring trunked systems. Does GPS signal strength get stronger or weaker at higher altitudes?

I did not, the radios were on my carry-on.

Please have the folks that when Sentinel gets updated, to add an option to AVOID any TE/DE's, then another option for those that are De/Te. TY! I'm manually having to avoid those in sentinel.

Also maybe somewhere, but cant find it.
Add options for 'Display Options' tab when target is the desktop 'external power' for Squelch, Keypress along with all the sub options that are available for the scanner themselves. Unable to access the option when sds200 is selected.

Similarly when sds100 is selected, but is not greyed out, but only options are at 'external power' is backlight off or on.

Does the SDS150 have an automatic clock? It would be a shame to have to manually set the time on an electronic device designed in the year 2025.

Best description of how the SDS filters work that I've read.

If a scanner has a IFX feature it can be done to use those "filters" that SDS scanners are using. We don't have access to any schematics for x36 scanners but we have for the BCT15x and it shouldn't be any different to any other Uniden scanner that uses a IFX feature. It uses two IF filters it can select between, one at 380MHz and another at 265MHz like most Uniden scanners, including SDS and x36.

If we receive a frequency of 465MHz then the oscillator are generating a frequency of 200MHz to be mixed with the input signal to generate a third frequency of 465-200=265MHz that fits the filters center frequency.

There's also a second oscillator that generates a frequency to mix with the 265MHz signal to produce a 10.8MHz for the final IF filter. Lets simplify that and make it a 10MHz frequency and the 2:nd oscillator will then operate at 255MHz. 265-255MHz=10. If the first IF filter used where instead the 380MHz one then the second oscillator are programmed to be 370MHz. 380-370MHz=10MHz.

The PLL circuit IC used in BCT15x handles both those two oscillator signals, one program register for the 1:st IF and another for the 2:nd IF and both are programmed independently from the CPU the instant the scanner change frequency.

To use a SDS type of "filter" you make the wanted signal pass thru the 1:st IF filter at its edge, lets say it will be at 260MHz as the filter can be +/-5MHz wide from its center of 265MHz, then any received unwanted frequencies that makes its IF go below 260MHz will be more or less blocked by the filter as it will be outside of the range where it will let frequencies pass.

To make it 10MHz for the final IF to still receive the wanted frequency of 465MHz the second oscillator are then changed from 265-255MHz=10 to be 260-250MHz=10 to still produce that 2:nd IF signal of 10MHz.

Uniden have always had those wide IF filters as they are cheap to produce and buy and have never been any real issue that needed them to operate like in a SDS scanner, so no point in introducing those filter settings in any other scanner than SDS as they don't need them.

There are all sorts of replacement latches on Ebay.

I know the batteries can't be switched. I just asking cause the 100 door clip was breaking. I wish that one guy was still around to buy a few more of them.

 

[garys]

That reminds me of how people would complain that Uniden scanners didn't have battery packs and then when Uniden switched to battery packs, the same people complained about that.

Well did you like where it was on the SDS100?
People wanted it changed and they got it.

Good afternoon Sunday , doing some reading but unless I missed it will BT support audio too headphones ,any confirmation on that ? When will we see a release ?

 

[buddrousa]

I know the thread is long but your question has been answered multiple times in this very thread.
Bluetooth to phone app only with audio from the phone.

I'm currently in Florida. I plan on testing the 150 and 100 around the Lee/Collier County area.

I'm in Charlotte County just north, I'm pretty sure Lee Sheriff Dept is all E stuff. No clue on Collier County, just a tad far I think, but never tried.

It most likely does, it seems my SDS100 does, since it auto updates with the DST changes (if an external GPS source is connected) Since the SDS150 has GPS built in, there would be no excuse.

Plus, if I'm not mistaken, when you sync to your PC & Sentinel, the clock is also synced.

I would also assume, that it also syncs via the U/Aware app.

Probably syncs with GPS as you said, otherwise a ridiculous oversight.

My 100 has never touched a GPS and it keeps time better than a multi-thousand dollar APX8000 and updates DST with no intervention on my part.

 

[buddrousa]

As does mine Kevin the only difference is all of my SDS100's are connected to GPS's.

Same here. I've had the Uniden GPS hooked up to my 100 once when I first got it. I only update about once a month or less, and the 100 and 200 do a lot better than most clocks you'd hang on a wall.

I have this Alinco-branded, old-fashioned bedside quartz analog clock with a dial round the outside that you can turn to see the time in different cities around the world. I bought it over 20 years ago from Universal Radio.

I'm kind of obsessive about maintaining accurate time on my non-WWVB devices and I swear this little clock is almost as accurate as the atomic clock generated WWVB signal. I know not really, but it outshines any other quartz timepiece I've ever owned, you can set it by the WWVB signal, leave it for weeks, check it again, and it's just a couple seconds off.
