The leaving the control channel is very suspicious. Have you tried a new memory card just in case?
I've got plenty so I'll give that a try as well. I only listen to MARCS so I can't really compare to much of anything else.

I played with the waterfall this afternoon and it's definitely a cool feature. Not 100% sure what I'm looking at, but I'll definitely post some things.

Thanks for the help and tips, guys...

GREAT call! Put a fresh one in, errors are at zero and the RSSI is much more stable. The noise level is even lower, and NOAA even comes in so much better in my living room...

So how the heck does a card make that much difference?

Uniden really needs to improve their data integrity check in the firmware code. All frequencies that should be scanned and monitored are read from the SD card and put in RAM working memory for quick access by the CPU. When a carrier are found it reads additional data from the SD card to try and match the data that have been decoded from the transmissions.

If that additional SD card read are disturbed, difficult to read the data by some unknown reason, that somehow makes the RF reception be worse, then that are a major issue for Uniden that needs to be fixed.

I don't know how much ram is in the SDS150 but the only way to get fast read/write is enough ram on the 150 to hold the database in memory on the unit, or at least hold what you select to listen to. But with ram shortages globaly due to these large data centers being built, doubt it will ever happen.

Ubbe maybe you should design and build your own perfect scanner. Seeing you know so much. Please do I would love to buy a perfect scanner designed by you.
Maybe we can get back to the intent of this thread in regards to new firmware and any issues arising, instead of Ubbe's "my feelings are hurt because Uniden never asked me to write code for the scanners." which seems like every helpful thread goes down that rabbit hole.

I've been working 35 years with everything from pagers, cellular phone control centers up to country wide digital trunked system from portables audio issues to system level problems and I have been sent to different countries around the world to solve issues. I use my experience to try and explain to others, that could have less experience, what could be wrong when something doesn't work as it should. I give my own personal opinion of what I think is going on. Uniden might be listening or they might not.

Only the frequencies, that are needed to be able to scan, are initially loaded from the SD card to RAM and only takes up a couple of kilobytes.

They're not, @jasonhouk has the ear of Uniden and relays issues. The thread is/was about the new firmware release which I'm expecting something related to that when I receive an email of a new post on the thread and not another one of your anti-Uniden rants. As far as I know, Uniden has not released the SDS150E which would be for you in Sweden, and since you don't own one, might want to sit this one out. I'm more interested to read about those that loaded the firmware up and experiences they're having...that's what this is all about. Does it work...what happened if it didn't? This scanner is a powerhouse, and the firmware additions make improvements for those of us that own them. Let Jason handle communication with Uniden, they're listening.

I do not believe it is bad firmware few having problems and the majority are not.
Everybody using the same firmware and hardware some are having problems some are not the only difference is how the scanner is used. Could it have been writing to the drive when power was lost? Could it have been writing to the drive and got dropped? These are thing we may never know but the best answer is to wipe the drive and restore it from your PC or replace the drive? I travel with spares you never know the spikes that come from starting the car. Just make a new card and see what happens.

That's my point. Uniden needs to improve their check of data integrity if something have gone wrong with the data information that have been stored. Now it seems like users get no information that data are corrupt, the scanner just works in strange ways and you have to try and find out yourself by some random actions like reloading data or swapping SD cards and check if it made a difference.

I ran into this issue yesterday! I thought the RF front-end in my scanner suddenly went bad!

I loaded a new favorite list into my SDS200 yesterday morning. When writing to the SD card (the original from years ago), my PC complained about an issue with the card and attempted to fix it. Driving to work, my scanner heard NOTHING for the entire 30-minute trip. Halfway there, I turned on my SDS150 in the truck - it was picking up everything normally... So now I think my SDS200 went deaf and I have to troubleshoot it.

At lunch, I updated the SD card again with some new frequencies, this time with no errors reported. On the trip home, the scanner behaved perfectly normally, picking up the usual traffic. After reading the above - I'll be swapping out the SD card today.

Sorry if it's blurry, I'll see if I still have the package when I get home.
Yup I can see it good. I might give ordernone and give it a try. Mine acts a little wonky at times and maybe that will help.
By wonky I mean in addition to the occassional lost transmission issue (which has improved but still persists in rare cases) I also notice that even nearby P25 Phase 2 channels the reception sounds "skippy" or "choppy" on one out of every 10 transmissions. It's still copyable but somewhat annoying.
