Tone Tube

Code Practice Oscillator

Tone Tube

Code Practice Oscillator  (TT)

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 serves as a resonator. Visually, the Tone Tube matches  perfectly with Palm Radio's Portable Key, and Mini Paddle with Code Cube,  but can also any straight key or cootie key, and with most electronic keyers. A built-in small speaker produces a smooth, shaped wave tone which is adjustable in frequency and volume. This speaker is automatically turned off when you plug in a stereo headphone. The Tone Tube is supplied in Palm Radio's "travel case" and includes a spare battery.

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.
