Code Practice Oscillator »Tone Tube« (TT). Made in Germany.
Palm Radio had several inquiries about a small tone generator in the past, so the »Tone Tube« has been developed recently to close a gap in the delivery program. The gray electronics module with the speaker is mounted into a black plastic housing (ABS, enhanced impact resistance), which also serves as a resonator. The »Tone Tube« matches optically perfectly with Palm Radio’s PPK (manual key) or the Mini Paddle with Code Cube, but can also be used with any other hand keys or keyers. A built-in small speaker produces a side tone which is adjustable in frequency and volume. This speaker is automatically turned off when you plug in a stereo headphone.
Operating time (with a replaceable CR2032):
- Speaker, maximum volume – about 20 hours CW (20 mA)
- Headphones – about 200 hours CW (2 mA)
Key input and headphone output: stereo phone jack, 3.5 mm.
