In these days of internet training (or even good old fashion club/classroom courses) it can be expensive for a beginner to get a key and oscillator sorted for practice. The Signaller is a low cost way to dip your toe in the world of Morse. No external wires or batteries needed so a compact and highly portable way to practice your sending over Skype or Zoom (or even in a classroom / 2m FM!).
The key has an on board sounder and LED so your sending can be seen and heard by the instructor.
Now supplied as a Full Kit, you need to solder and assemble the key. Requires 2 x AAA batteries (Not Supplied)
Would be great as a club project or for anyone looking for a low cost way of practicing their Morse.
