MORSE CODE/TELEGRAPH CW OSCILLATOR - PITCH VARIABLE - TWIN T VERSION - WITH CASE

Description

Pitch Variable Morse Code Oscillator and Amplifier
Includes Laser Cut Custom Case
Includes a plug compatible battery clip, see photos.
Description:
A fully assembled Code Practice Oscillator (CPO) based on our popular 'Trinity' CPO using a Twin T oscillator configuration with custom laser cut acrylic case.
The Twin T gives a pure note compared to the square wave derived from say a 555 oscillator, this provides a more pleasing note and may allow longer practice sessions.
This variation of the 'Trinity' CPO incorporates a Pitch control that allows the operator to 'tune' the note to their preferred frequency, by means of an on-board potentiometer.
The range is approx. 400 Hz to 2000 Hz. Several smartphone apps are available that  allow you to adjust the tone precisely by having the app 'listen' to the output of the CPO, if you find difficulty in finding your desired tone by ear.
Suitable for
straight
(non-iambic) keys only.
Overall size of the cased unit is; 3.75" W x 2.5" D x 1" H (+/-)
Please note: PCB color may on occasion vary from that shown in photographs, also adjusting knob colors may vary from batch to batch compared to photographs.
