MORSE CODE/TELEGRAPH CW OSCILLATOR - PITCH VARIABLE - TWIN T VERSION - WITH CASE:
Pitch Variable Morse Code Oscillator and AmplifierIncludes Laser Cut Custom CaseIncludes 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 forstraight(non-iambic) keys only.
Overall size of the cased unit is; 3.75" W x 2.5" D x 1" H (+/-)
