PSR500/PSR600: Settings for Harris P25 systems

OP-25 interface

I've attached a picture of the web front-end to my OP-25 installation. I use a Dell 3179 hybrid laptop/tablet that I bought from Dell's Outlet site for $285 (after a 15% off coupon). My only other cost was for the RTL-SDR dongle ($25) and a cheap omni-directional antenna ($10). The Linus OS and OP-25 software is free.

The nice thing about my laptop is that since it's a touch screen, the softkeys can be selected with a push of my finger on the screen. In reality, the software will run on just about any old computer you may have laying around. In the display, Group Addr is the trunk group number and Source Addr is the transmitting unit's radio ID. I connected the audio out jack to an old set of computer speakers I had laying around for better sound.

What is this "front-end"? How did you make it look like that?

OP-25 front end

After loading the program with the following:
"cd ~
git clone https://github.com/boatbod/op25
cd op25
./install.sh"

I added the loopback address to my rx.py command, then I started a web page and pointed it to my loopback address. My rx.py command looks like this:
"./rx.py --args "rtl-0" --gains 'lna:36' -O 'default' -S 2440000 -U -T trunk.tsv -l http://127.0.0.1:8080"
I then start Firefox and I set "127.0.0.1:8080" (without the quotes) to be my homepage

If you read the last 20 pages or so of the VirtualBoxProject thread under the Software Defined Radio section you'll see how to implement some of the latest improvements. Several really smart guys continue to improve this program and I just take advantage of their hard work.
