[op25-dev] Beginner's Guide To Setting Up OP25 From Scratch

Here are a couple of steps to insure that your Airspy device is available to your Ubuntu VM.

*	Remove one of the Airspy devices.  You do not need two devices in rx.py. 
*	Set /verify that the remaining Airspy device is virtualized in your VMware settings menu for the Ubuntu VM.
*	Start the Ubuntu VM then execute lsusb from the command line.  It should return somethings like the lines below if your Airspy devices has been virtualized.

op25 at op25-VirtualBox:~$ lsusb

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 003: ID 1d50:60a1 OpenMoko, Inc.       <-- This is the Airspy device

Bus 001 Device 002: ID 80ee:0021 VirtualBox USB Tablet

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

*	Now execute dmesg from the command line.   The terminal output should have lines similar to these.

5.911019] airspy 1-2:1.0: Board ID: 00

[    5.911024] airspy 1-2:1.0: Firmware version: AirSpy NOS v1.0.0-rc10-0-g946184a 2016-09-19

[    5.914976] airspy 1-2:1.0: Registered as swradio0

[    5.914980] airspy 1-2:1.0: SDR API is still slightly experimental and functionality changes may follow

Your VM must be able to see the Airspy before proceeding to debug your rx.py command line and trunk.tsv files.

My Airspy is the R2 and has different sampling rates than the Mini.    You must specify the correct sample rate on

the rx.py command line that is supported by the Mini.

Well, I've gotten a little further but am stuck on this part.  I've got 2 Airspy Minis plugged in and if I run the following:

../rx.py --args 'airspy' -N 'LNA:10,MIX:10,IF:10' -S 2400000 -f 769.28125e6 -o 25000

I get a lot of errors (screenshot):

So is there any way to trouble shoot all of this?  Thanks.

Thanks for the dummies link.  Just what I need!  It looks like there's another step to install something called GNUPLOT:

sudo apt-get install gnuplot-x11

As mentioned before this is likely the most recent how-to:

A year ago I wrote this, when it was just starting to be a thing to install OP25 on a Raspberry Pi:

While I don't have any desire to run op25 on Windows, unfortunately I can see a good how-to on that sort of thing being desirable to many.

I am a ham and I like to tinker, not just be a end user.  So I don't see anyone using this on Windows really contributing anything back to the community.  I really urge people to dig into things deeper than skin level, you never know, you just might learn something.  But that is just me.
