Look at post #10. @pinballwiz86 included a pic of a scanner frequency w/ the WF. The link(which I read before I made the post) doesn't show, how to get off the FM band.
Did you really not see the TO SCAN soft key? It's right on the display, and the manual spells it out to exit waterfall mode. C'mon man, at some point you have to RTFM and figure things out for yourself.

Wow it's an early Christmas present from Uniden! It's working great on my SDS100. Simple to use! Very intuitive. Showing a visual 17 MHz swath of the frequency spectrum on a police scanner is COOL. $20 is very reasonable as well. Great job Uniden!!

Does anyone know how to listen to P25 audio in waterfall mode? I park on the voice channel not the data channel, and the activity is displayed on the screen, but I don't hear anything. The "span" is only 2.88 mhz, and I did try using "hold." I'm going to guess that you cannot listen to digital audio since the Preset Waterfalls are all analog signals and they don't have listed any frequency ranges where you would normally find digital signals. I wonder why it can't decode digital voice in waterfall mode?

I know the picture shows a data channel here but I just wanted to show the waterfall in action and I had started scrolling around. lol.

Digital voice channels are sporadic. What I have done is to go to Radio Reference to see what frequencies are in use for the tower site I am monitoring. Then I tune the scanner to one of those voice frequencies and just wait. EVENTUALLY the channel will come alive just briefly. I have also been lucky enough to tune over to one of the waterfall lines and hear a transmission there. It just takes patience. That is why I really do not see how a waterfall display is at all useful for a scanner. It is just a pretty gimmick to impress your friends.

I would be useful to search for and find new frequencies in use. However, now my friends can be impressed on how I paid an extra $20 to make my $700 scanner deaf on UHF.

This conclusion has been drawn of course after attempts to try the six remaining filter settings (including off) were fruitless?

Yes. And clearing the cache didn't help either.

From what I can see using the new waterfall feature, it look the update put it slightly off frequency about 1khz too high. This signal shows plenty strong on the scope, but it cannot center on it. A filter isn't going to fix this.

the request for a tuner app to fix this slightly off frequency condition is here

I do have a later model of the SDS200 but I have to say I have not experienced any of these desense or off frequency issues. I guess I'm fortunate. I offer the filter suggestion as it seems apparent that many people aren't even aware of their existence and a simple change to another setting can have amazingly positive (and sometimes negative) results.

I reiterate that for $20 it's a pretty nice addition to the scanner, and I make that statement with some serious experience with SDR tech to include the great display on the IC-R8600 receiver and a ton of Airspy dongles. I think Uniden is off to a good start with this and hopefully some tweaks will make it better. My biggest fear is wearing out the function knob, but I'll still primarily use the aforementioned SDR's for spectrum analysis.

Hello, I've sorta been trying to follow along with this....

Been using SDRs for several years now. How does the waterfall compare to SDR paired with SDR# or FMPx?

The waterfall feature is a GREAT WAY to wear out your selection knob on the scanner. You have to turn the knob to tune the
scanner over to the waterfall line of interest. Click-click-click-click-click dozens of times. By the time you get the scanner tuned where you want it, the transmission is over and has gone away. And there is no way to even know what that exact frequency was!

Now, let's think about SDR. What does SDR mean? Software Defined Radio. But what does THAT mean?
It means you have an expensive transceiver that is being controlled by software that is running on a pc or a laptop
or dongle. When you see a waterfall display, all you have to do is point and click with the mouse and the radio
zaps right over to the requested frequency. On the scanner you would still be click-click-clicking away to no avail.

Save your twenty bucks. A waterfall feature is NOT that useful on a scanner.

Pressing the FUNC key while scrolling speeds up the marker movement, minimizing the # of clicks. The Waterfall can be a great tool if you like to find active freqs at "Events" where two-way radios are in use. Much better than a Custom Search as you see the entire spectrum at a glance. Very quick way to find what is in use. In my opinion.

Also, if you have @ProScan, you can use the computer to move the control. Never have to touch the scanners knob. I have a feeling Bob from Proscan will implement the waterfall display into the Proscan display on your computer also.

Dare I ask....did you not save your $20?

Incidentally, unless I'm completely misreading and/or misinterpreting it, your definition of software defined radio baffles description. I read it at least five times before I hit the "Post reply" button...

Just an FYI, there is a "Hold" button that stops the display in its tracks so you can go over and tune to it at your own speed to get the frequency
