W9RAN Pico RX Presentation W9DYV 2025

The Pico Rx is an amazing inexpensive yet full-featured 0-30 MHz SDR receiver created by Jonathan Dawson - 101Things. This presentation from the 2025 W9DYV Technical Symposium describes the Pico Rx and my version of both the Simple Pico Rx and a first look at the coming Pico Rx-Tx which uses an innovative 4th method of generating the SSB waveform.

That's a very good presentation! It's been a pleasure working with you on this project!

Very nice presentation, with Jon's pico-rx concept laid out in a easy to understand video!

incredible :)

Here’s a free idea. 😂. How about implementing the receiver filter on your TX module. That way it would have the correct band pass on RX to match the TX module that is installed.

Good idea! In fact, the Rx-Tx board taps the receive signal off at the input to the class E matching network, which provides selectivity and impedance matching. A future project is to do a sweep to see just what the response curve looks like.

This is wonderful. 73s de va7wpx

Did you use Julia/Makie to do your animations?

[@w9ran]

No, Jon Dawson created them all in Python. All can be found in the Simulations directory at github.com/dawsonjon/PicoRX
