WISCO RADIO CW Trainer — learn Morse code (CW) the way hams actually use it, from your first two characters to a full on-air contact. Fully offline. No account, no network, no ads.
• Koch-method lessons — every character at full speed from lesson one, with Farnsworth spacing; a new character unlocks at 90% accuracy.
• A six-rung copy ladder — single characters, pairs, random groups, ham words, callsigns, and full QSO phrases.
• Sending practice with a built-in iambic paddle and straight-key decoder that shows exactly what your fist sends — including the HH "start over" prosign. Key on screen, with the keyboard, or with your own paddle or straight key through a USB adapter (VBand-compatible — the [ and ] keys).
• A QSO simulator with POTA, SOTA, IOTA, and ragchew contacts — on-air break-in fills, honest signal reports, and a 5-second "get ready" countdown before the code starts.
• Realistic band conditions — selectable receiver filtering (wide / CW 500 Hz / APF), QSB fading, and AGC.
• Reference guides on CW lingo, on-air procedure, and the history of the code.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
On Arch Linux, snap can be installed from the Arch User Repository (AUR). The manual build process is the Arch-supported install method for AUR packages, and you’ll need the prerequisites installed before you can install any AUR package. You can then install snap with the following:
git clone https://aur.archlinux.org/snapd.git
cd snapd
makepkg -si
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
If AppArmor is enabled in your system, enable the service which loads AppArmor profiles for snaps:
sudo systemctl enable --now snapd.apparmor.service
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Wisco Radio CW Trainer, simply use the following command:
sudo snap install wr-cw-trainer
Browse and find snaps from the convenience of your desktop using the snap store snap.
