    Thanks Ricardo, imaginative use of the Arduino

    Excellent little VFO. Can you please suggest the pin changes and code changes to use an Arduino NANO. Thank you.

    • @pu2clr
      @pu2clr  ปีที่แล้ว

      NANO is also based on Atmega328. So, you can use the same pin numbers. You can use the same schematic and code.

    Ricardo, just came across your channel and you have a lot of really cool 😎 videos. I recently got an si5351 and hope I can get it running. Anyway, thanks for posting your content. 73...

    Подскажите-такие искажения меандра-это норма?Смеситель сможет с ними нормально работать?Как синус сделать симметричным,или необязательно?

      Para esta finalidade não foi preciso tratar o sinal de saída. Não creio que você terá ganhos significativos ajustando o sinal para uma senoide. Mas, não sou um especialista no assunto. Apenas estou compartilhando algo que funcionou em meus experimentos.

      Acho que postei um vídeo no TH-cam que mostra como faz a calibração. Nele é possível observar isso. Acho que 10MHz.

    Olá Ricardo, estva pensando em usar, este seu circuito em um velhinho radio PX Motoradio FAM21, somente como receptor. O que vc acha? Abraços

    • @pu2clr
      @pu2clr  5 ปีที่แล้ว

      Não conheço a arquitetura do rádio. Mas, acho uma excelente iniciativa para ser testada. Conte comigo para auxiliar no entendimento do programa ou mesmo nos ajustes caso isso seja necessário. Se o seu experimento funcionar, gostaria de documentar e postar aqui neste repositório para ser compartilhado com outros colegas. O que acha?

    We did it with the Aduino program. It's a program operation, but it won't work if you turn down the frequency! It also happens that you have to reset the frequency settings at power off.
    I think we should be able to get the set frequency again using internal memory! We will modify the memory so that it can be stored. Am I the only one who can't move when the frequency has to be lowered?
    Please reply. Good luck!

    • @pu2clr
      @pu2clr  5 ปีที่แล้ว +1

      I think I did not understand your issue. What kind of low frequency are you talking about? Have you had problem with the encoder or you want a frequency below than 8KHz? Yes, if you need to save the current status of your signal generator into the internal Arduino memory.

    Hi recardo, I have used some of your project radio sketches, they function very well, I am using all in one si4732 radio sketch!! I want to remove 2 bands from the sketch FM and LW. IS IT DIFFICULT TO DO THIS, I want to keep all the other bands. Thanks for help.

    • @pu2clr
      @pu2clr  ปีที่แล้ว

      Try commenting out the lines referring to the bands you want to remove (add //): Band band[] = {
      // {LW_BAND_TYPE, 100, 510, 300, 0, 4},
      {MW_BAND_TYPE, 520, 1720, 810, 3, 4}, // AM/MW from 520 to 1720kHz; default 810kHz; default step frequency index is 3 (10kHz); default bandwidth index is 4 (3kHz)
      {MW_BAND_TYPE, 531, 1701, 783, 2, 4}, // MW for Europe, Africa and Asia
      {SW_BAND_TYPE, 1700, 3500, 1900, 0, 4}, // 160 meters
      {SW_BAND_TYPE, 3500, 4500, 3700, 0, 5}, // 80 meters
      {SW_BAND_TYPE, 4500, 5600, 4850, 1, 4},
      {SW_BAND_TYPE, 5600, 6800, 6000, 1, 4},
      {SW_BAND_TYPE, 6800, 7300, 7100, 0, 4}, // 40 meters
      {SW_BAND_TYPE, 7200, 8500, 7200, 1, 4}, // 41 meters
      {SW_BAND_TYPE, 8500, 10000, 9600, 1, 4},
      {SW_BAND_TYPE, 10000, 11200, 10100, 0, 4}, // 30 meters
      {SW_BAND_TYPE, 11200, 12500, 11940, 1, 4},
      {SW_BAND_TYPE, 13400, 13900, 13600, 1, 4},
      {SW_BAND_TYPE, 14000, 14500, 14200, 0, 4}, // 20 meters
      {SW_BAND_TYPE, 15000, 15900, 15300, 1, 4},
      {SW_BAND_TYPE, 17200, 17900, 17600, 1, 4},
      {SW_BAND_TYPE, 18000, 18300, 18100, 0, 4}, // 17 meters
      {SW_BAND_TYPE, 21000, 21400, 21200, 0, 4}, // 15 mters
      {SW_BAND_TYPE, 21400, 21900, 21500, 1, 4}, // 13 mters
      {SW_BAND_TYPE, 24890, 26200, 24940, 0, 4}, // 12 meters
      {SW_BAND_TYPE, 26200, 28000, 27500, 0, 4}, // CB band (11 meters)
      {SW_BAND_TYPE, 28000, 30000, 28400, 0, 4}, // 10 meters
      // {FM_BAND_TYPE, 6400, 8400, 7000, 3, 0}, // FM from 64 to 84MHz; default 70MHz; default step frequency index is 3; default bandwidth index AUTO

    A partir de qual frequência a forma de onda começa a ficar mais próxima de uma onda senoidal?

    • @pu2clr
      @pu2clr  4 ปีที่แล้ว +1

      Marcelo Roberto Gadotti acho que tenho um vídeo no TH-cam onde apresento a calibração do dispositivo. Nele, isto pode ser observado. Mas, se não me falha a memória, 10MHz.

    Excelente trabajo, y le hago una pregunta con respecto a si yo tengo un equipo que trabaja en 3,5-7 y 14 mhz con fi de 2 Mhz, con modificarlo el bfo sirve o hay que modificarlo el offset para suma o resta de la frecuencia de salida? Gracias y muy buen trabajo

    • @pu2clr
      @pu2clr  5 ปีที่แล้ว +1

      Creo que si. Este dispositivo tiene tres salidas de señal distintas. Creo que para su demanda solo necesita usar uno que variará 2MHz más y menos.

    • @walterantoniosilva7147

      Gracias por responder, voy a probar y le comento si logro la modificacion para mi equipo,desde ya le agradezco que comparta lo suyo,lo felicito y le informare. Gracias!!!

    Olá Ricardo queria poder usar esse circuito e um yaesu ft101zd , mas ainda não achei o arquivo exato pra fazer as funções no Arduíno , lembrando que eu estava pensando de usar as saídas do si5351 uma pro vfo e outra fazer a vez do oscilador locar , bom é só uma ideia , si puder me ajudar . forte 73

    Anybody else getting the message: "ISO c++ forbids converting a string constant to 'char*' " when compiling?

    • @pu2clr
      @pu2clr  4 ปีที่แล้ว

      Is that a warning or an error? Actually you are trying to use a string object as a point of char datatype.

      @@pu2clr Hey Ricardo. Thanks for responding. 🙂 I am new to Arduino, and this is my first ever Arduino project that i try to recreate, so im not sure. I think its a warning, because the lights were flickerkng and blinking and (i think) i uploaded it to the board (Nano).
      Ps. When i posted the comment i wasnt done with the wiring of all the components so i was thinking it was because of it that i got that warning message, i dont know.
      I am going to try it again soon when all is set up according to your schematic you have up on Github.

    A potentially excellent video but your unwillingness to talk ruined it.
    Reading is distracting.
    Just tell us about the circuit.
    We don't care what your voice sounds like.

      Thanks for the advice. Written communication is easier for me. Maybe my laziness and, above all, lack of opportunity to try to get more fluency in oral communication led me to that approach of content. Sorry for that.
