some of my favorite links
well, this is a list of some of my favorite links. it will grow.
Qsstv, a free and open-source SSTV program, the best in its category. probably available in your package manager
PySSTV, it generates SSTV signals, although in less formats than what the QSSTV program can generate. probably available in your package manager
a cool page about the PD SSTV signal modes, these are my favorite due to them being high quality, ranging from 50 to 290 seconds with tons of modes that vary a lot in resolution and error correction and probably more, and being open!
an useful SSTV-related guide to get you started, especially useful if you want to transmit SSTV
same as above
a cool article on the history of SSTV and more
an WebSDR radio that i use to receive SSTV transmissions at 14.230 MHz in what seems to be USB mode.
another radio i use for the same purpose
where i found G0XBU's WebSDR radio
FLdigi, a free and open-source program which allows an ordinary computer's sound card to be used as a simple two-way data modem (i've seen it be used for weatherfax). probably available in your package manager
an WebSDR radio that i use for receiving weatherfax
a free and open-source cross-platform software-defined radio application which allows you to navigate the radio spectrum and demodulate any signals you might discover. probably available in your package manager
RTL-SDR for Linux Quick-Start Guide
RTL-SDR is a cheap dongle for receiving radio signals
Receiving Slow Scan TV images from space using GNURadio and a Terrestrial TV receiver dongle
Using Gnuradio to Introduce Digital Radio Concepts to Amateur Radio Hobbyists
Wireshark, a free and open-source program that may be the most popular network protocol analyzer. one of the uses i have seen of it is seeing how much microsoft windows phones home without the user's consent, though, of course, you can do much more than that. probably available in your package manager
i2pd (I2P Daemon) is a free and open-source, full-featured C++ implementation of I2P client. I2P (Invisible Internet Protocol) is a universal anonymous network layer. probably available in your package manager
a comparison of compression algorithms
a page about software freedom
privacy vs. "i have nothing to hide"
a manual for QSSTV, generated by Doxygen (it's pretty nice). unfortunately it's no longer available from that address (the only one i could find for the manual, iirc), thankfully we have the internet archive to continue viewing it from the web instead of downloading the qsstv source and generating the manual from the .doxy file (well, i mean, you could probably just view from the source of the manual, but the generated output seems to be comfier, at least for me)
