I read that the SDS 150 can decode TDMA CCs is that true? Is it possible to firmware update the other SDS scanners or wud that be something they wudnt do even if they cud to get us to buy the the 150 and future 250?

It is true per Jason and the Manual as to the 100/200 with firmware has not been posted.

Voice channels use the same 12000bps bit rate as a P25 TDMA CC so no problem to support that in a SDSD100/200. The P25 guys initially made it a legacy 9600bps CC to be P25 I compatible to be able to run the systems voice channels in mixed mode and upgrade to new subscriber radios in steps.
It's about selling new products. Where I worked they came out with a new 2-way radio model almost every year and they made sure that its battery connectors where not compatible with any old battery types, and the same with any accessories like hand mics.
If a company constantly improves and enhance old models they do not get to sell any new products.

You mean two TDMA TGs on the same channel, right? Two timeslots, one channel.
Yeah except I deleted my post cause I realized you were asking about CCs, a totally different issue than I was addressing.

I do experience this on my SDS 200 as well.

Ya supposedly they are working on it, hopefully they will get that fixed. @natedawg1604 and myself brought this up in another thread and @jasonhouk said they are working on things, so hopefully next FW.
It also be great to get TDMA CCs decoding on our SDS 100, 200, but I doubt they will do that, its a reason to get us to buy the new version of SDS. As @Ubbe pointed out the 100, 200 receive the 12000 bps bit rate so it be no problem to add that to them with a FW update.

Yall keep talking about Firmware updates the SDS100 has very little room left.
For current firmware versions, the amount of free flash memory is:
Just remember the 436 does not have all the extra screen real-estate that the SDS100 does nor does it have as many functions.
The space is very limited to work with.
For current firmware versions, the amount of free flash memory is:
- BCD436HP - 380KB
- SDS100 - 90KB

I have only the SDS 200, but I assume it's about the same free space as the 100.

There's enough space to work with. A guy has modified the firmware without taking away anything but added all decryption systems from Moto/Hytera Basic up to AES256 set per frequency, site or TG and added new functions to some buttons and displaying the encryption type detected on the display without running out of memory. If removing that autolocate feature in the scanner, that probably no one uses, you can get even more free memory.
Board of directors meeting: "Will we sell more scanners if we add TDMA CC to older scanners? No, we will sell less. Who came up with this stupid idea? Next item on the list please."

As I have said before I will stick with Factory Support.
As I have said before Build your own Scanners and sell then sense you know so much.
Last time someone modified factory software a Bomb was loaded into firmware.
Yes, firmware is considered intellectual property (IP), generally protected under copyright law as a form of software. It acts as low-level, embedded code that controls hardware, and unauthorized copying, modification, or reverse engineering of this code is typically classified as IP infringement.

Key aspects of firmware as intellectual property include:
- Copyright Protection: Firmware code is protected by copyright law from the moment of creation, granting the owner exclusive rights to reproduce, distribute, and modify it.
- Trade Secrets: Proprietary algorithms, processes, and code within the firmware that provide a competitive advantage are protected as trade secrets.
- License Agreements: Firmware providers often use License Agreements to define user rights, restrictions, and protect their IP from unauthorized use.
- Legal Protections: Manufacturers may use techniques like encryption, digital signatures, and watermarking to prevent illegal cloning and, if necessary, use legal frameworks like the Digital Millennium Copyright Act (DMCA) to combat piracy.
- Derivative Works: Modifying firmware is often considered creating a derivative work, which can violate the original owner's copyright.

So... someone is making unauthorized changes to copyrighted software? I'll take "What is Illegal Hacking for 200." Also, I would like to know what data you base your assumption on that no one uses the autolocate feature. And I am guessing by your quote of a board of directors meeting that you are not a huge fan of Uniden as a whole?

Just an explanation how a company works. They need to make a profit to be able to continue their business. They do not decide what's best for their customers but what are best for the company to increase profit. It's common business practice to abandon old products and make a new with a couple of new features, even if those features could have been included in the old product but that would hurt sales.

True; however, the user agreement may apply to different laws internationally. Or not. I do not claim to fully understand US laws much less laws in other counties.
I understand that companies are in the business to make money and not necessarily want to make decisions to include things customers want but could hurt sales. Your board comment seemed a bit harsh but I probably read too much into it.
So, to answer the OP's question, I am in agreement with you that it is unlikely that Uniden will push a software update for older SDS radios (SDS 100 and 200) to include a feature exclusive to the 150 so as not to cut into sales of the 150.
Let's get back to discussing whether or not the SDS150 can decode TDMA CCs.
