Is there SDR software out there that will work with a NooElec to allow one to scan like a scanner?

There are a number of plug-ins for SDR# that will do what you want: SDR# and Airspy Downloads - airspy.com

DSD+/FMP24 scans via a scanlist.
DrProcessor scans via a scanlist.

i use RTL_FM and you probably already have it
it can scan many different ways
it will even scan SSB
i pipe the audio to SOX to give it a 200Hz PL tone trim then off to Pulse for play back
like
rtl_fm -M fm -d 1 -p 69 -f 45.4400M -f 151.0550M -f 151.2800M -f 153.7400M -f 153.7700M -f 153.8300M -f 153.8450M -f 153.8750M -f 153.9950M -f 154.2950M -f 154.3400M -f 154.4300M -f 154.7550M -f 155.0400M -f 155.0700M -f 155.1450M -f 155.1600M -f 155.1750M -f 155.2800M -f 155.2950M -f 155.3400M -f 155.3700M -f 155.4000M -g 30 -s 11025 -F 0 -l 70 | play -v 1.5 -t raw -b 16 -e signed -c 1 -r 11025 - sinc .2k
how this is done in windows I have no clue, but the tool is there
I run two instances of the this (two dongles) with different scan lists on a old EEE box
and use Byobo to let me run the 4 SSH sessions i use to run all of it,without having to restart everything, this is accessed on a web page
I am thinking of passing the audio to a Icecast server on the same machine which would let me listen anywhere in the house
the big draw back is you dont get any feedback on what channel your on and you cant "skip" on the fly
but once you have a list of channels you want, it seems to play very well
I know there are other ways to do this, but I wanted fast and cheap using the tools already on board
ohh yeah no digital
but we dont have any ones and zeros here

There is more than one way to do this but probably the "easiest" way is to use the SDR# software with the Frequency Manager Suite plugin installed. This will allow you to create a group of frequencies and scan within them.

I specified that I had a NooElec because I couldn't get SDR# to work with it. So I'm assuming SDR# is incompatible with a NooElec SDR.
Or maybe I'm doing something wrong...

Find the instructions for installing the Zadic drivers - and you will be up and running fine on SDR# - SDRSharp is a good software to start with.

Sdr# works with the rtl chips just got to install the right drivers. Windows installs a incompatible driver and it has to be replaced. The last time I downloaded SDR# in the zip file was a file to install the proper drivers I believe it was a .bat file.
I'll give it another go when I have time.
See if this helps:
That looks simple enough.

Run the install bat file included in rhe SDR# directory.
Select the right input in SDR#
Make sure you ran the ZADIG and selected the zero not the one dongle
The NooElec runs great with SDR#

this is almost exactly what I did (save I didn't listen for a 200hz PL tone), and then I switched over to just RTL_TCP from a openwrt AP that is lightly loaded and stream the I+Q to my LAN so any of a half dozen GNUradio apps, SDR#, phone apps can access it locally and I can pick and choose.
sorry, this is a bit of a thread hijack (but the RTL_FM fu that k9wkj warrants compliments). To stay in the tune of the OP, the nooelec SDR is fully compatible with SDR#, it's operator error. Enough people before me have mentioned the Zadig instructions, follow them carefully and it will work.
I'll have a run at this maybe tonight.

actually I am using SOX to do a 200Hz highpass filter so I dont have to listen to the PL tones
I fiddled with that value to get the tones out without trimming the already to narrow NFM even more

Answering your original question, I'm working on scanner software for SDR dongles. It's in Alpha though so it's buggy, but I plan to announce it publicly in the coming weeks
strong work. I saw that re-reading this thread after I posted.
That sounds like quite the challenge! Good luck!
What rate are you going after? Multiple SDRs per host or just 1?
SDRs are notoriously slow at frequency shifting, and a little unstable, not to mention requiring the CPU to process all that data over a USB bus before giving it to the userland program to process, but if you've got something that works...go for it!

it was quite a bit of tinkering to get it to do what I wanted
-g 30 -s 11025 -F 0 -l 70 | play -v 1.5 -t raw -b 16 -e signed -c 1 -r 11025 - sinc .2k
and the terse documentation made that construct a fiddly enterprise
but I got a listenable output with working squelch
