Pitch Variable Morse Code Oscillator and Amplifier Includes Laser Cut Custom Case 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/style may vary compared to photographs.
