Ham Radio - The CW flea project update. Design and software done.
Would it hurt to include a summary of the project and video in WORDS ?
Great project Jim, thanks for sharing it with us.
My only comment is why not add a display to show frequency ?
A VFO project by Julio Cesar using the same parts as you has a small color LCD display.
I built his circuit and it works well. Display would require SCK, SDA, +5v and ground connections and a few extra lines of code.
Anything to do with QRP and CW is fantastic. Thank you.
What about using Pin Diodes for QSK and adding a button for 1Mhz jumps for band jumps.
Hi, Kevin Loughin is the content maker his YouTube channel is fantastic. Thank you for posting this link it looks really educational and a great learning experience.
Nice to read, thanks!
Thanks--Great info on the page.
Agreed. A nice, concise couple of paragraphs is much more likely to be read by someone unfamiliar with the project than watching a 30 minute video.
A class AB final using BS170 mosfets will give 1W+ with 5 components at a cost of $1.
Neat project. I’d substitute the parts on your low pass filter with SMD and consider using an optocoupler rather than a mechanical relay—it’s QRPp.
You may want to turn to the schematics of HackRF for further inspiration.
I would pursue Analog Devices MAX4567 or something similar. Regardless of which direction you take this project, you're brilliant. You've really given meaning to software defined radio.
Agreed 100% on a summary with words. I'm not so much into videos, and had MUCH rather read an article, or at least a short summary.
