40 METER LIVE CW QSO with W2XB using this remote setup:

the remote site where the remote op is located, is a WINDOWS 10 computer, over the internet, connecting to the K3S Elecraft's Raspberry Pi hardware/software interface via Tight VNC viewer and JackTrip(audio). The audio from and to the K3S, is achieved in low latency using JACKTRIP(has…

- IAMBIC and STRAIGHT KEY from:https://github.com/recri/keyer

- cw keyboard is from FLdigi : http://www.w1hkj.com/

once built and compiled, the Recri Keyer software will allow both STRAIGHT KEY and IAMBIC KEYER at the same time via a USB MIDI DEVICE(s)…

Using a Raspberry Pi hardware/software interface connected to an Elecraft K3S rig, this video live demo's how it works to use the RazPi remote config to connect to the K3S over a remote ip location from another computer in real time... and receive and transmit cw and ssb.(i was able to qso cw with W8ACM for this demo)

Basic Setup…

An experimental setup simulation for a RASPBERRY Pi LAN PARTY using 6 Raspberry Pi cw ops - all connected to the Ethernet switch/router local area network...sending and receiving morse code MIDI DATA to each other, using QmidiNet with LINUX NATIVE REAPER providing all the morse code software to convert cw audio to midi messages for transmit, and…

The Raspberry Pi is first setup as a code practice oscillator using LINUX NATIVE REAPER and its own plugins. Then using a circuit similar to this: http://i.imgur.com/C2qYIPm.png , a 555 timer chip is keyed by a FET optoisolator that connects to a CW KEYER's key-RIG OUTPUT jack. In this video a…
