The 436 has filters?
The 436 has filters?

Antennas: Good catch—I had the stock 436 duck on the left and a 700/800-specific antenna on the SDS150 (the one that came with my 100, actually). We did swap antennas between the two scanners and repositioned them side-by-side, front-to-back, and even swapped steering wheel locations—same outcome every time. The SDS150 held solid voice; the 436 still chopped or completely deaf.I'm not trying to be picky about the test 436 vs 150; but I noticed you used the 436 stock antenna vs 700/800 antenna on the 150.
Did you switch antennas at all?
Defeats the purpose of spotlighting simulcast hash. But fair point—scan mode vid could be a fun follow-up. I have no ETA for my next trip to CBus, a steak dinner does sound nice if anyone in the area is offering?Why wasn't the 436 in scan mode instead of id search mode?
Absolutely—FUNC + VOL to check/adjust error rate is scanner gospel, and I had the 436's digital threshold set to Auto. Setting this to manual could have helped, but in peak simulcast overlap, you're still fighting physics. The SDS150 front-end just shrugs it off better out of the box.Did you adjust the 436 filter for best error rate by pressing the func button then the volume button then the func button and volume button to bring up the error rate display?
If I was closer and you'd bring that 150, we could talk, but it's some distance for me to come meet you there.Defeats the purpose of spotlighting simulcast hash.

Do you know what the block diagram is for the SDS150? Where is the SDR chip in the system. RF front end, IF?Antennas: Good catch—I had the stock 436 duck on the left and a 700/800-specific antenna on the SDS150 (the one that came with my 100, actually).

Point of posting this on RR was to let the community know we’ve been field-testing the SDS150 since early April 2025 and I'll assume Uniden engineer's even prior, and the results have been consistent across multiple runs.
I'll refer back to post #422Do you know what the block diagram is for the SDS150? Where is the SDR chip in the system. RF front end, IF?
Understood. Thanks.I'll refer back to post #422
I can confirm that little rascal is roaming and not with the rest of the litter. I seem to have another one roaming around, needing found!Hey @jasonhouk, I found this 🐈⬛ out roaming around!
Are U/Aware?
It's about time that Uniden America Corporation freshens up their lineup.

Thanks for reply.Yes you are right.In fact just wonder if the non e & e will become one model to cover all markets. That might be best ?The SDS200E cannot be had "naked" and it comes with all protocols enabled. You can only add the waterfall. The same has happened to the SDS100E that it used to be available in different versions with different protocols enabled but now it's only two versions, all keys installed or without ProVoice. But I don't understand why the need for two version as it is a €50 difference and going to Uniden Australia for upgrade of SDS100E it will be the same €50 to get the key for ProVoice.
I'm sure that Avera will do the same to the SDS150E and only offer versions with all keys installed as you don't buy a SDS scanner and only use it in analog mode. The GPS are of no use as there's no database from Uniden for European countries that could make use of location based scanning and as the SDS150 have a much improved speaker audio then the bluetooth connection seems more or less redundant if only used for audio.

Did I hear someone SSN# ?Early testing with the engineering sample sent to me. I was testing the SDS150 vs the 436HP about dead center between all the simulcast towers on Columbus City MARCS.

I'll wait and see what the reviews say for improved sensitivity. If it isn't at least as sensitive as the 996P2 in the 2M and air bands, it's not worth an upgrade to me from the SDS100. Too much encryption to keep upgrading these without a larger benefit elsewhere in the package.
Especially with strong adjacent signals in the same band.
Only way I see that happening is if dPMR is made a common feature.Thanks for reply.Yes you are right.In fact just wonder if the non e & e will become one model to cover all markets. That might be best ?
Well when you don't have any competition you can kick back and relax a bit.It's about time that Uniden America Corporation freshens up their lineup. This is long overdue.
is there a picture of the back?@jasonhouk - the new profile picture??? that's a pretty bad AI botchup! But according to the picture, its an SOSISO, not an SDS150, so maybe Uniden is working on something even newer??? AI doesn't get Halloween?

Was waiting for someone to mention this. The SDS filters are completely different, and were first introduced in the SDS series.BTW adjusting Digital Decoding on the 436 is not adjusting filters.
Well I'm not a technical GURU like you guys are. I should have just said menus to adjust the error rate. Sorry for using the wrong technical language.BTW adjusting Digital Decoding on the 436 is not adjusting filters.
