Better CW. Better remote radio.
From the first Morse character to a clean high-speed fist—and from CGNAT to an unattended remote station. Practical answers from real operating and engineering experience.

OpenShack CW
From the first character to a cleaner fist.
Five guides for learning, improving and mastering CW—with receiving and real sending treated as one operating skill.
Learn Morse by sound
Use fast characters from the start, with Koch progression and Farnsworth spacing that gives you time to recognise them.
Start learning CW →Characters become words
Bridge the gap from single characters to groups, words and callsigns with Advanced Trainer and Morse Game.
Build CW fluency →Push every CW skill
RufzXP, RufzXP TX!, PileUp, CW Summit, Quality RX and one-minute TX runs for measurable progress.
Push your limits →Improve during real QSOs
Keep TX Decoder open, review what you sent and make character and word pauses as clean as the elements.
Take better CW on air →OpenShack Remote
Seven guides for the real station.
No generic remote-desktop advice. These guides cover the network, CW transport and hardware questions that matter when you actually want to make QSOs.
CGNAT, DS-Lite and IPv6
How OpenShack finds a direct Peer-to-Peer path where possible and switches to its server path where necessary—usually without router work.
Read the networking guide →Jitter without broken timing
Why packet arrival times must not become CW timing, what the jitter buffer does and how delay spikes are handled.
Read the CW timing guide →Host Box or Client Box?
The Host Box integrates CW and PTT at the station. The optional Client Box adds the ultimate paddle, sidetone and footswitch experience.
Compare the Box positions →Your paddle over the network
One Box beside you and one beside the radio, carrying CW timing and PTT independently after configuration.
Understand Box-to-Box →What your station needs
Windows 11, RX/TX audio, Hamlib radio control, CAT options and the role of your existing radio interface.
Check the requirements →Power only when you operate
Wake the host PC with a networked smart plug, let OpenShack start the station and shut everything down safely afterward.
Plan unattended power →Radios and station devices
Hamlib radios, OpenShack extensions, amplifiers, tuners, rotators, antenna controllers and other supported equipment.
