Raspberry Pi Learns Slow Morse Code
It wasn’t long ago that you needed to know Morse code to be a ham radio operator. That requirement has gone in most places, but code is still useful and many hams use it, especially hams that like to hack. Now, hams are using the Raspberry Pi to receive highly readable Morse code using very low power. The software is QrssPiG and it can process audio or use a cheap SDR dongle. There are a few reasons code performs better than voice and many other modes. First, building transmitters for Morse is very simple. In addition, Morse code is highly …read more http://pje.fyi/Q0qvjD

Hans Summers' Ultimate 2 QRSS Kit (which I've maintained is the most fun you can have legally in ham radio for $25 + shipping) has received a much-desired upgrade.
The upcoming Ultimate 3 will sport a cool new blue backlit LCD! This will make things much easier on my aging eyes in the dark, dank, spiderwebbed corner of the basement that is my shack.
For those not familiar, check out the page and read through the operating manual to see what can be done (WSPR, FSKCW, CW, Hell, etc.) with this little gem of a kit. I can't stress enough how much of a no-brainer purchase this is at this price. The build is quite easy and the fun you'll have far, far surpasses the cost. Just don't buy them all before I get mine.
I have the first two generations of Ultimate QRSS Kit and this will be my third. The first (single band 30m) is out making the rounds amongst local hams, and the second has gotten much use in my shack, its 100mW WSPRs heard as much as 15000 km away down under.

The kit supports the following modes: + QRSS mode (plain on/off keyed slow CW) + FSK/CW mode (frequency shift keyed slow CW) + DFCW mode (dual frequency CW, dit's and dah's on different frequencies) + WSPR mode (Weak Signal Propagation Reporter) + Slow-Hellschreiber (frequency shifted slow Hellschreiber) + Hellshreiber (full-speed standard Hellschreiber, and half-speed Hellshreiber) + CW (plain CW) + Customisable FSK patterns
