SDR Limits
From the linked article:The Problem with Software Defined Radio https://t.co/adnsZEjh6p— hackaday (@hackaday) July 29, 2016
The key feature of the LimeSDR, and all boards derived from Lime Micro’s tech is the LMS7002M. It’s a Field Programmable RF transceiver with coverage from 100kHz to 3.8GHz, a programmable IF filtering from 600kHz to 80MHz, and — this one is important — on-chip reconfigurable ‘signal processing’ and a fast USB 3.0 interface to a computer.
APRS: Xastir and Raspberry Pi
WZØW's Xastir on the Raspberry Pi:
"A while back I got interested in APRS. My only 2m radios were a Kenwood TM281A in my car, and a dual band HT. Neither had TNC capabilities built in, though, so the first order of business was to get a TNC that I could use on one or both of these radios. I had seen an article by Jerry Clement, VE6AB, in the May 2015 issue of QST about a bluetooth-capable TNC fromMobilinkd that works well with HT tranceivers and APRSDroid on Android smartphones. I decided to give it a try, and it worked well, as advertised.
Then I started wondering, if I used a Bluetooth USB adapter on a Raspberry Pi, could I use Xastir to set up APRS on my base station. The punchline of the story is yes, I could."
