VK3HN: Multiband PLL VFO with Arduino Nano and si5351
This homebrew DDS VFO/BFO uses an Arduino Nano and an si5351 (Adafruit). The script was sourced from Tom AK2B's blog (acknowledging Przemek SQ9NJE) and uses Jason NT7S si5351 library. I have added support for multiple VFOs, mode and band selection, a basic s-meter and rx muting to the script. The plan is to use the VFO in a dual conversion superhet receiver, based on W7ZOI's Progressive receiver. — Paul VK3HN.

How to copy a 433MHz signal with an Arduino board
This method is very simple and only requires a few components : I used an Arduino UNO board, a XY-FST RF emitter module and a XY-KM-5V RF receiver module.
The method using audacity is very simple too but requires some resistors : the output voltage of the module can go up to 4V so I had to decrease it with a voltage divider to 1V maximum (for the audio input of my computer's soundcard)

Arduino AD9850 NE602 Superhet all band reciever
This I s my little AD9850, Arduino, NE602 super-heterodyne all band receiver. It goes from 0.517 — 30mhz continuous with basic front end tuning. The VFO is a thing of absolute beauty. This configuration was conceived by AD7C Rich:

The receiver is loosely based on Bill Bowden's NE602 superhet receiver:
http://www.bowdenshobbycircuits.info/radio.htm
The BFO is a one transistor type with an IF can. Of course this receiver will someday be assembled into a case. I wish I new more about getting rid of false images, - IF frequency stuff... I dedicate this video to my favorite You Tube channel Ko Tilmans "Radiofun232". His videos got me back into electronics. No shematic for the receiver, it's very simple.
