Классная идея и реализация. Учусь обращаться с SI5351 в том числе и с помощью вашего кода. Спасибо за Ваш труд. Здоровья и благополучия Вам и вашей семье.
Your logic is impeccable. This is indeed the heart of pretty much any sort of HF rig. The rest is just mixers, filters and amps for various bands. I like it. I just wish there weren't chip and RF transistor shortages right now. It's real frustrating.
Thanks for commenting John. Yes, if you strip out the VFO, BFO, CW carrier generation, keyer, TR switching, band switching, display only the analogue stages are left. I'm expecting to do another small run of this board at some stage, this time with si5351 on the board, and ideally, the SM ATMega MCU. But alas, no or extremely limited stock. The semiconductor shortage is stopping a lot of projects and kit development and I don't see it getting back to normal for another year! 73 Paul VK3HN.
No. The board works as shown but has some labelling errors. I could fix these and put it all on github, if you are keen and would go through with the build. I've moved on to a board half the size with a XIAO ESP32 and 5351 on board. I'm also writing new software that will include additional features such as CW decode on both Tx and Rx. This will be about another 3 to 6 months, based on current rate of progress.
Excellent project. I love it. How can I get few PCB's. I have been a HAM for 35 years. Still I don't have a HF rig. I like to do some project using PCB & Arduino Sketch. 73 de 4S7DB Daya Buddhadasa
Thanks Daya. There are a few errors on the boards . I intended to do a second run to fix these, but life got in the way. So I prefer not to release this project, as people would need ti.e consuming email support. I hope to get back to this so.eday. 73 Paul VK3HN.
Hi Doc, this is the prototype. So far I have discovered about 5 minor errors, mostly label mistakes. I wll fix these up before doing a second run and then release Gerbers. I don't know if I will order a larger batch of PCBs, depends on interest. The alternative is that with the Gerbers people can order their own, from whoever they prefer. I'll notify you in a matter of weeks! 73 Paul VK3HN.
Hi Stephanie, this is the prototype. So far I have discovered about 5 minor errors, mostly label mistakes. I wll fix these up before doing a second run and release Gerbers. If you subscribe to my channel I'll notify you in a matter of weeks! 73 Paul VK3HN.
Paul bravoo,excelent and interesting project...you know i have many dds hi!hi! but i m interesting ,on your project can i change the bfo frequency from rotary encoder ?thanks in advance Paul
Hi Mladen, how are you? Good to hear from you. My script does include code to tune the BFO across the IF passband. I have not used that feature for a while but it should still work. Will try it sometime soon. Stay well, 73!

Thankyou, I hope your project goes well. I invite you to leave comments below my blog pages for this Controller if you have any questions. Best 73.

Amazing
Microcontrollers and PLLs are amazing.
You're really taken this to an entirely new level. Two bad RUclips only has a single "thumbs up," Paul.
Haha, thanks Jack, appreciated!
DIid you release the gerbers?

Very professional job - as always Paul!
Thanks Nick, the .CN PCB and assembly certainly lifts it to a new level!
This is brilliant, thanks for explaining it clearly and sharing.
Glad you enjoyed it! Thanks again!
i am really confused
What is confusing you about this project?

Very impressed Paul well done a very handy project to have , Just a inquire, are you ever consider selling any of those boards ,Cheers 73's

is it possible to have the gerber files ?
