n00b - What's next?

[studysession]

New to all things SDR.
1st thing I did was the hello world with GNURadio. 2 radio stations with sliders on the screen.
Then navigate SDRSharp to do FM radio.
Then get op25 working for Maryland Carroll County Emergency Radio.

Prefer to work with Ubuntu than Windows but either for learning...Just looking for recommendations. Not sure what is the next stepping point from here.

What is a good stepping point from here?

Trying to take it easy and slow and learn all I can.

Thank you

Own: 1 RTL-SDR, 1 HackRF One

There is some programs for setting up base stations and dispatch centers using sdr. Would be fun to look into

What are you running Ubuntu on now? A Raspberry Pi 3B+ is relatively inexpensive and can do that too.

For the RTL-SDR you can run Gqrx. I use Gqrx on a Mac Mini, but it will install on the Pi too. You just cannot get to crazy with the band spread, as the processor on the Pi works only so well. Gqrx SDR for the Raspberry Pi – Gqrx SDR

You could run the Pi headless after you get it configured by using VNC Viewer to login and give you a GUI. Let the Pi do the work and let your other machines do whatever, just use one of them to login to the Pi when needed. I have some Windows tablets I use when out and about and use the RTL-SDR directly for quick things, but using the Pi instead takes the load off.

Pi3 makes a rather inexpensive P25 ph2 trunk scanner.

I am running it now on 2 systems
DELL Laptop
Installed: Ubuntu 18.04.1 LTS

Raspberry Pi 3
ubuntu-mate-16.04.2-desktop-armhf-raspberry-pi

I have loads of Raspberry Pi's. I love these things.

Boatbod -

You have a tutorial for receiving pagers? Think I want to d pagers as my next attempt at something.

I don't do much with pagers except wear one
What sort of pagers do you want to decode? Lots of different systems out there...

Hi again - it has been working great. Have couple of questions.

When it opens I have to use the arrow keys and make it go left twice to be -200 at the bottom of the screen.
What do I put in the command line to make it just be -200 when it start?

I keep reading in FB groups how people use more than 1 RTL-SDR for scanning but this works with just 1, do I use more SDR's to get better coverage?

Thanks - This has been lots of fun - greatly appreciate all the help.

If you type ./rx.py -h and it will show you what each thing does.
One of the is a offset start with it at zero and adjust it from there, also check the offset in the trunk.tsv file.

Use -d -200 in your command line for this.

THANK YOU so much
