After I finally got OP25 working on a raspberry pi - I went a little crazy. I wanted a portable version. And here are some attempts of some of my ideas....
I picked up the small SDR dongle from eBay for a few dollars, I didn't like a large dongle hanging out of the Rpi. Turns out it is really really bad, and very heat sensitive.
See description in the pictures for more info, I ran out of characters to fully document 😉
While I had OP25 running on one of my Raspberry PIs, I was using a bluetooth speaker at night so I could listen in while in bed.
Worked great, but moving away from raspberry pi and to a laptop that doesn't have bluetooth. I lost that ability.
That was something I missed, then I remembered The bluetooth speaker was also able to be used as a Chromecast device.
Installing MKChromecast on linux was fairly easy, getting it to work was a bit of a challenge. But once you get it - it works well.
