In this video, I delve into the ESP32-S3 based Band Surfer VFO, demonstrating its functionality by connecting it to an old 11-meter transceiver. I also guide you through the process of compiling the C++ code, along with the necessary libraries, using the Arduino IDE.
If you encounter any challenges, don't hesitate to reach out to me at m0xfx.channel@gmail.com. I'm considering creating a FAQ video to address common questions about this project.
Join me as we explore the capabilities of this innovative VFO and learn how to implement it in your own projects!

The code will only support this IC at this time.
2.2", 2.4", 2.8" or 3.2" sizes will work fine.
Also we are using a no touch display but a touch will work fine but
the VFO has no touch control functionality.

Hi Chris, great to hear from you as always.thanks for the nice feedback, I will do my best to make some more videos regarding projects. I have some repair vids lined up as well which should be interesting as I have 2x 101ZD's sitting in the workshop. 73 John

@christopheriles1469 4 месяца назад

My apologies John, I haven't had time from work to build the Bandsurfer yet but rest assured, I will certainly build it. The "breadboard" vfo works flawlessly so I'm fired up to build the Bandsurfer. Your excellent videos have made this "do-able", thank you so much for all the time and effort you have put in. Bless you, Chris, G0VOE, Somerset.

Love this VFO. How much of a transceiver is already part of the boards you supply? I’m guessing band pass filters and an RF Amp will be needed to add to the boards to get a basic build? Love it!

@user-se5jc3gw1y 4 месяца назад

Beautiful John .... looks to be highly functional .... Thanks for your work! ----- Dean, KL7MA

@M0XFXUK 4 месяца назад

Hi Dean, no problem it's been quite a fun project to develop. Now we have architecture of the code under control we can add a lot more features. I am currently working on a band pass filter array which can be controlled by I2C and automatically switches in front end band filters controlled by the VFO unit. If you have any ideas for features let me know and I will do my best to incorporate them. 73 M0XFX

@Tokyo1991.JL1AJE 4 месяца назад

Great content! Noticed half of your parts links are jumbled up. Definitely would appreciate you fixing them. Also where there are purchase options for example the touch screen, it would be great if you could be explicit/specific about which part you used as I’ve purchased items claiming a certain driver being used only to find the size I opted for used a different driver. Have you considered using JLCPCB or similar to offer your boards for on demand purchase. I think you get a cut and it would expand your follower base as Chinese shipping seems to be much cheaper than almost anywhere else. 73 John

@M0XFXUK 4 месяца назад

Hi John, you make a good point. Apologies I hadn't considered how the part links come out on a phone, I will certainly take a look at this. Regarding the LCD driver IC, I did mention that I was using the ILI9341 in the description but I can see where the confusion came into play. I will update the descriptions to be more specific. On that note, I am planning to add code for different display driver IC's, which driver did you purchase? Regarding JLC, I know this outfit and I am considering using them or PCB Way for manufacturing pre assembled boards. Thank you for the information, much appreciated regards John M0XFX

needs rit (clarifier) on a pot ..nice project

@M0XFXUK 4 месяца назад

Yes, very good point, an RIT is certainly something it could do with. I'm thinking of using a rotary encoder with a push switch but I could also look using a pot. Thank you for the comment.

@salawalas 2 месяца назад

Great project, indeed. I'll try to do this myself. Popular and ordinary esp32 Devkit v.3 will be work? I mean esp32-dowd-v3 rev3.1.

@M0XFXUK 15 дней назад

Hi apologies I have been busy with work commitments of late. With regards to your question: I am used the ESP32 S3 however; I guess it would work with esp32 Devkit v.3 but you may have to may have to change to GPIOs the code to suit that board. I hope this is of help.

@Paul_VK3HN Месяц назад

Well done, thats a lot of work. To squelch the radio do you stop the VFO?

@M0XFXUK 15 дней назад

Hi Paul apologies I have been busy with work commitments of late. No the squelch works by the micro controller comparing the signal level with the squelch level and switching on a transistor which grounds out the squelch circuit in the transceiver.

@acestudioscouk-Ace-G0ACE 4 месяца назад

A great video John, thank-you! As a beginner, could I build this project straight off or am I better to build your Build & Code Arduino first?

@M0XFXUK 4 месяца назад

Hi, It's pretty straight forward to build and to configure. I feel that the videos are becoming a little fragmented and making it hard to follow for beginners. I am putting a guide together that will go through step by step on how to build and configure the Band Surfer VFO. Keep an eye on this video description as I will add it when I've completed it.

@pitupongkliangsan410 2 месяца назад

are you interested to add gps 1 pps output to automatic adjust si5351 frequency stability?

@M0XFXUK 15 дней назад

Hi apologies I have been busy with work commitments of late. To be honest I have developed a new Si5351 breakout board with a 2ppm TXCO which has improved the frequency stability and I have also added an FM modulation feature to the new breakout board. With regards to GPS steered frequency stability is not something I have given much thought to. I believe that he type C variant of the si5351 can be controlled by a variety of reference frequencies which would be interesting to see how it performs with GPS locked standard but is not something I have had the time to play with. Thank you for the comment as it's good food for thought. regards John M0XFX

Hi ! Is it possible to use regular ESP32 WROOM instead of ESP32-S3?

@M0XFXUK 15 дней назад

Hi apologies I have been busy with work commitments of late. regarding your question, Yes I don't see why it shouldn't work however depending what features you use you may need to reassign the GPIO's to suit. Thank you for your comment.

@Toyko.1991. parts list is fine. I ordered all the p0arts I needed including the touch screen from that list it wasnt hard at all. Mine is up and running no problem. It works extremely well. I use JLC myself for my pcbs but also use PCBWay when I get pcb's populated. JLC use a chine supplier for a lot of their parts. I much prefer genuine ones from Mouser etc. as that is what PcbWay use as their p0arts supplierI get pcbs assembled for aircraft engines and prefer to get all genuine manufacturer parts and it not that much more expensive.

@Tokyo1991.JL1AJE 4 месяца назад

I use PCBWay as well for fab. The parts list format is better when viewed from a desktop. Appears out of sync on mobile if you click from the middle of list as opposed to working through in order. YMMV. Never had a good experience ordering LCDs from AliExpress. Shoddy packaging/cracked screens or bizarre drivers as I said.

@SimjetAU 4 месяца назад

@@Tokyo1991.JL1AJE I use a desktop or a laptop..cant stand using a phone for that..its tiresome as you stated. The encoders John suggested are very good surprisingly for the p0rice as well. I got it all from Aliexpess inc the touch screens and all arrived fine and well packed. used Johns links. I am waiting on the I2C encoder Adafruit boards...they are coming from Mouser and should be here this week as couldnt find any on aliexpress
