  • FREQUENCY BARACUDA

    Hello.

    Who could help me add a frequency adjustment on the barracuda??

    THANK YOU

    you can not use freq above 600Hz because it will be high tone.
    is it your intent to decrease the tone to 100...200Hz?

      hello

      I do not want to change tone, but add a frequency adjustment. I have a lot of interference on the beach or I am with radio ferry boats.

      On TDI, there is a frequency adjustment.

      little being too I have to learn how it works

        in Bara the sound tone and the TX freq is same, same schematic. if you change the freq you get sound changing too.
        also, meeting question, is you Bara DIY or fabricmade?

                Look at Fig. 4 ( TX Oscillator) on page 12 of the build document, try putting a Pot in series with R10
