I have not been able to pick up any NSP transmissions on my Homepatrol scanner for the last several weeks? Is it my scanner or has something changed. I am a novice at this stuff, and would appreciate any information.
I am not very familiar with HP1, however, NSP went through talkgroup changes over the past few weeks, you may have out of date talkgroup info in your HP1, from which I understand is dependent on the RR.com database info. You may want to check what is programmed into your HP1 against the NWIN talkgroup database.
When I went through your area earlier in the month, Troop D had plenty of radio traffic.
If you need help getting to know more about your HP1, go here:

Also, keep in mind NWIN is a Motorola SmartZone System, if there is not a Trooper/NFM etc.,"affiliating" to your nearest tower, you will not hear anything. The nearest tower for you should be Site 45-Cozad
Here is a good write-up about Motorola SmartZone and trunking altogether:
