Just released my new app, rtl_icecast.

"A command-line application that uses RTL-SDR to receive FM radio signals and stream them to an Icecast server in MP3 format.

The main target usage for this app is to stream your local HAM FM repeater audio to your public shoutcast/icecast server with just a RTL-SDR USB-receiver and for example Raspberry Pi. It can be used to stream broadcast FM too, of course."

Not sure how old this is, but AntiX Linux boots up super fast on this old Sony Vaio i7 with 4 gigs of RAM. I'm very impressed with this distro. I've installed a suite of rtl_sdr programs on it and it works great. Fast web browsing, and terminal web browsing using Links2 which I haven't done in a while, just for fun.
Video is of the boot process up to the login screen.

Been trying to receive NOAA APT satellite signals for the past ~week using an rtl-sdr dongle & a basic V-dipole. Yesterday, I ordered and received an LNA to boost the signal. Combined with a pass of NOAA-15 that basically went directly overhead, I was able to pick up this (composite) image. Which did not decode correctly, because clouds do not look like that (I didn't save the raw signal).

But I managed to get a signal, which is progress and very exciting to see!

Sometime down the road I'll build a QFH (a helical antenna) which should dramatically improve the signal quality.

A composite satellite weather image. The background is a raw satellite image of western North America, from southern Mexico up to northern Canada & Alaska. I did not record the background image. Overlaid on the satellite image is raw decoded APT signal from NOAA 15. In the center, between approximately the Oregon/California border up into British Colombia and stretching across the entire width of the image are white bands, which might indicate clouds, except they look like straight lines. Indicating that there was a failure to correctly decode the signal. Outside of this stretch of white bands is static over the rest of the image.

I first heard about #SDR in the late 90s and didn't think about it a lot, because I figured that was something that would forever remain in the realm of supercomputers and/or custom FPGAs, so I would probably never work with it.

I (foolishly) did not anticipate that by 2023 I'd be able to buy an SDR receiver for $40 that would fit in my pocket (#rtl_sdr), or a transceiver for $300 (#hackrf), and just plug it in to my laptop (or phone).
