Thoughts on a Wideband SDR Recording Tool

As part of the HamSci Solar Eclipse experiment, I recorded wideband data from my SDRs on the theory that capturing the data for later study might be more productive (and less stressful) than trying to do measurements in real time. I think that theory played out very well. I used a simple Gnu Radio flowgraph to do the recording from an HPSDR Hermes receiver. When I say simple, I mean simple. Here’s the whole thing, which records four 384 kHz […]

Since my updated post on building a P25 trunking scanner with a Raspberry Pi and an RTL-SDR dongle, I’ve created a copy-and-play image file that gets you up and running in minutes. I’ve put it (along with a couple of other RPi image files) at http://febo.com/pages/os_images/. The filenames are somewhat long, but modestly descriptive so you should be able to figure out which to download. Once you have the file, unzip it and copy to an 8GB SD card. Put […]
