The “Hello World” of the embedded and micro controller world seems to be the
blinking LED. Finally got around installing Win10 IoT on a RaspberryPi2 and
deploy some code. All works fine.
The extensive and complex wiring
The extremely detailed GUI for headed mode

Quick hack just for fun …
And it makes nice signals too
Made the board for the K5TRI Ardukeyer based on K3NG’s code so that
I can use paddles with the TS-940S.
I used Eagle for the schematics and PCB layout and then transparencies
printed in the laser printer and heat to get the layout onto the board. Some
time bathing in Ferrite-Chloride Acid does the rest.
Quick hack with an LM-386 for an audio amplifier I needed for one
of our rooms.
And finally found an enclosure:
Signals looked nice and clean on the scope and sound is sufficient for it’s
Took some time tonight to re-build my FSK interface for the TS-2000 and
add CW keying for the upcoming ARRL DX CW contest. Looks much nicer
now. Schematics are here: http://www.aa5au.com/rtty/fsk-interface
Also had to made a pig tail to get all the signals out separately to be
able to use it with multiple radios.
Update 4/8/2016: Code is now on GitHub https://github.com/michaelschulz/rotorduino
I finally found some time to post the source for my rotor controller I posted about a long time ago. Maybe some day I will also find time to make the schematic. I never drew schematics in a proper tool other than on a piece of paper. It should however be somewhat self explanatory. As the saying goes:”The documentation is in the source” :).
Got another TS-2000 (again). It is a good radio after all. Tried next to a TS-590S
I could not make out a dramatic difference in weak CW signals. But that amber
display light … that’s just wrong 🙂
I wrote about the process here before. Next up the 1st IF tap to hook up an RTL-SDR.
