The si5351 frequency correction feature is not included in the sketch. For the frequency correction method, rewrite XTAL_FREQ in si5351a2.h in the src folder.
1. Search for the following content written on line 25 of si5351a2.h in the src folder #define XTAL_FREQ 25000000 // Crystal frequency for Hans' board 2. Check the transmission frequency (25MHz) of the si5351a module with a frequency counter or receiver, etc. 3. Rewrite XTAL_FREQ to the confirmed frequency.
If you recompile, the frequency corrected value will be reflected.

First of all, thank you for this project ☺️ I would like to use the third clk output from the si5351a, is it possible to activate it. I would use this as a carrier output without if.
DD1MR OM clk2 is set as BFO, but does that mean clk0 VFO1, clk2 VFO2? No problem. I think it can be done with a little modification. Please tell me the specific frequencies of clk0 and clk2. I think I can give you a more correct answer.
DD1MR OM The si5351 library used in this sketch is a compact library. Currently using 99% memory. It turned out that there was insufficient memory for this modification.
Previously, the method of writing to eeprom was by pressing the RIT SW.
However, since I sometimes forget to do the operations, I made it so that if nothing changes for a few seconds after operating the encoder, it will automatically write the eeprom.
This is because the step of writing the header comments to the eeprom from the previous manual operation remains. Please ignore this line.
おはよう. Please, in the register configuration of the si5351a.h file, it seems to me that it is possible to configure 4 different output levels, P3 seems to be the maximum level, close to +12dBm. In order to mix the OL in my project, I would like to reduce the level which is much too high, moreover this will significantly improve the spectral purity... Would you like to know how to proceed with these registers? Congratulations on your work. どうも ありがとう ございました

Nice Project ..
how to add an IF settings menu, so you don't have to always upload via a computer?
thank you
The nano is 99% with 30674/30720 bytes of memory.
Adding functions such as IF menuing is possible without bootloader. However, I don't think there is any importance in creating an IF menu.
no problem , thanks for sharing a very good project
excelent like always ..thanks for nice project!73 de Mikele 9a3xz
Mikele Good evening
Thank you
Good Project !
Alex Good evening
Thank you
The VFO using a 2.2-inch TFT is now working perfectly. Thank you.
I would like to know more specifics about calibrating the Si531, please.
Is the Frequency offset used for that?

いつも大変参考にさせていただいております。
気になったので投稿させていただきます。
このプログラムのtimepassed変数ですが
setup()時に一度初期化されているだけですが
222行目のFlg_eepWT = 1;をした後にも
timepassed = millis();を追加するのが
よいかと思いました。
私は以下のような処理に変更してみました
// Flg_eepWT = 1;
if (freq != freqold) {
if (Flg_eepWT == 0) {
timepassed = millis();
}
Flg_eepWT = 1;
}
よろしくお願いいたします

ミスコール失礼しました。お詫びします。
早々にコメントありがとうございます
ご認識の件も了解いたしました。
他のスケッチも見させていただき
あれ？との思いでコメントさせていただきました。
すばらしいソフトの公開ありがとうございます。

了解です。
突っ込んだコメントはなかなか貰えてなかったので、大変感謝してます。

clk2 is set as BFO, but does that mean clk0 VFO1, clk2 VFO2?
No problem.
I think it can be done with a little modification.
Please tell me the specific frequencies of clk0 and clk2.
I think I can give you a more correct answer.
clk 0 is VFO and CLK 2 is BFO yes. I want to use CLK 1 as carrier output ( frequency without adding If ) only the frequency shown in the display.

OK, thank you very much for your answer 🙂

I have a question.
What does " Memory Operation is Push RIT ' mean?
Previously, the method of writing to eeprom was by pressing the RIT SW.
However, since I sometimes forget to do the operations, I made it so that if nothing changes for a few seconds after operating the encoder, it will automatically write the eeprom.
This is because the step of writing the header comments to the eeprom from the previous manual operation remains.
Please ignore this line.
OK thank you

To change the output level, rewrite si5351a2.h.
To change the output level of si5351aSetFrequency, change line 171.
Si5351_write(CLK0_CTRL, 0x4F | CLK_SRC_PLL_A);
8mA 0x4F +13dBm
6mA 0x4E
4mA 0x4D
2mA 0x4C +3dBm
Can be adjusted from approximately +13dBm to +3dBm.
To change the output level of si5351aSetFrequency2, change line 225.
Si5351_write(CLK2_CTRL, 0x6F | CLK_SRC_PLL_B);
8mA 0x6F +13dBm
6mA 0x6E
4mA 0x6D
2mA 0x6C +3dBm
Can be adjusted from approximately +13dBm to +3dBm
Why i can not download files from https://sites.google.com/view/ja2gqp?
I have 403 error :(
There is no problem at all.
I don't know why.
