si5351 VFO

Adafruit si5351モジュールを使ったVFOで、LCDにnokia5110 を組合わせた。DUAL VFO方式を採用し、BFOを自動選択方式にしてスイッチを減らした。チャンネルは、0-9(max10ch)でバンドに割り付ける事も可能だが、同一周波数帯としても使える。RITは、±10kHZ。Sメータ機能付き。周波数帯域外は、over表示して送信不可。また、送信時はスイッチ操作が出来ない様、誤操作保護を行っている。SPLIT機能は、メモリ不足の為、優先順位から除外した。   
 

部品実装基板である。0Ωは、ジャンパーとして使用している。部品の大半がジャンパーなので、PCBとして出来が悪いかも知れない。 



回路図である。nokia5110のバックライトは、現時点で電源印可の違いで、2種ある事が判っているいる。
タイプ1 BL端子 VCC接続
タイプ2 BL端子 GND接続
バックライトのタイプの違いに対応する為、ジャンパチップで設定する事にした。

基板寸法 93 x 47

  1. 始めまして、すばらしいVFOですね。
    是非作ってみたいと始めたのですがコンパイラでエラーが出て進みません。
    aruduinoIDEは1.6.5です。エラーは、
    Si5351 si5351;
    の部分で、内容は以下のようです。
    GQPVFO:100: error: 'Si5351' does not name a type
    GQPVFO.ino: In function 'void setup()':

    'Si5351' does not name a type

    IDEのバージョン等問題があるのでしょうか?
    何かお気づきの点があればサジェッション願えないでしょうか。

  2. IDE1.6.9を使ってますが、1.6.5でも問題なくコンパイル出来ました。
    ただ、気になる所は、Si5351 si5351の行98なので、それ以前の行を変更修正してませんか?単純なミスだと思います。

  3. 早々有難うございます。
    特に変更はしていません。
    どうもライブラリーがうまく合致していないようで、再度貴記載のものを入れなおしてみます。
    Rotaryライブラリーは、Rotaly.LIB.zipですね。これはrenameの必要がありますでしょうか?

      発振周波数のキャリブレーション方法は、スケッチの例のEtherkitSi5351にあるsi5351calibrationを使えば、補正周波数を得られます。補正値をスケッチに組込む方法も書いて有るので、よく読んでください。
      周波数安定性は、水晶発振子の負荷容量との関連も有ります。

      It is a method to make the frequency display 1/4.
      Fix have the Fnc_Lcd() and Fnc_Chsw().
      Fnc_Dsp(Vfo_Dat) from Fnc_Dsp(Vfo_Dat/4).

  19. Dear Akio,

    I use this sketch for my 3-band CW QRP RIG.
    It works fine. Thank you, Akio.

    Only problem is with RIT.
    When RIT is ON and I'm keying Tx low, the frequency is not set fast enough to Tx frequency.
    There is about 100 milisecond delay and this sound like a chirp.
    Did you test this with morse keyer?

    Have you any idea to solve this problem?

    1. Hi Alex.
      Because it is made of 2 channels with si5351a, the problem pointed out occurs when the transmission frequency and reception frequency are different. However, it should not be a problem if sending / receiving switching cycle like ssb is long. To solve the problem, I think that it is necessary to output 3 channels and output the transmission and reception to other terminals. Just I do not plan to fix sketches.

    1. In the case of SSB, you just set the carrier point for USB or LSB. I do not know how you want to remodel, but the frequency relationship just sets the appropriate value for my circuit. Although it is thing with lower heterodyne, since it is generally disadvantageous to spurious, it is better to use upper heterodyne. My VFO is designed with upper heterodyne.

  26. Hello Buddy Akio Mizuno!
    I've been trying to compile this sketch for a week now. I am using Arduino IDE 1.8.19. I downloaded the required libraries line - 20, 21, 22. In your sketch. Unfortunately, despite repeated attempts and hours, it failed to compile.
    The bugs list is too long for me to post here. Many of your projects have a "src" folder with all the required libraries in it… it's a pity they aren't in this project. Dear friend, could I ask you for a working sketch + required libraries. The bugs that the IDE showed ... there is probably a problem with the sketch as well. I made a PCB according to the attached drawing, I am waiting for the Nokia5110 display I ordered, but I cannot cope with the compilation.
    Kind regards

    The LCD5110_Basic library is designed to support various CPUs. Therefore, it is not suitable for saving to the src folder. Please register in the library and use it.

    Moved rotaly.h and si5351.h to the src folder. si5351VFO.zip has been updated. Please use this.

    In spite of wolohow4's explanation of his sketch, which I cannot get to work.
    For the radio I am using, I need VFO-IF frequency.
    I understand your explanation as well.

    I look forward to your modified sketch, please.

  31. Rewrite lines 107 through 111.

    //---------- Memory Assign --------------------------------

    volatile long LSB = 10701500L; // 10.7015MHz
    volatile long USB = 10698500L; // 10.6985MHz
    volatile long CW = 10700600L; // 10.7006MHz
    volatile long bfo = 10701500L; // start in LSB
    volatile long IF = 10700000L; // 10.7000MHz

    The sample has an IF frequency of 10.7MHz.
    The LSB frequency is IF+1500, so it is 10701500L.
    The USB frequency is IF-1500, so it is 10698500L.
    The CW frequency is IF+600, so it is 10700600L. Just adjust it according to your tone frequency preference, but generally IF +700 is preferred.
    Therefore, the CW frequency is IF+700, which is 10700700L.
    The bfo frequency sets the LSB frequency as the initial value. bfo 10701500L.
    IF frequency specifies the center frequency of the filter. The sample is 10.7MHz, so the IF is 10700000L.

  37. si5351VFO.zip The sketch dated 7/26/2023 reflects DEF when EEPROM is initialized. EEPROM initialization modifies the following lines:
    const byte Int_End = 73; // Initial end code
    Any other value for 73 initializes the EEPROM.

    Also, EEPROM writing is manual writing by RIT SW operation.
