Hi, my name is Dan and my ham radio callsign is M0WUT. I am developing an automated Raspberry Pi Zero based transceiver for the WSPR amateur mode. What is WSPR? WSPR stands for Weak Signal Propogation Reporter (full details WSJT Home Page) developed by Joe Taylor, K1JT. In short, amateur stations transmit data packets containing their callsign, their location and how much power they are transmitting with. Once received, these can be decoded by a computer who uploads them to a central databas ...
If you are here to see how to add Ethernet / soundcard functionality to the Pi Zero, this is a part to be used in my automated amateur radio WSPR transceiver. Explanation of which can be found here: WSPRpi part 0: Introduction and what is WSPR? If you are not interested in how I intend to use it and just want to see how to add Ethernet or a soundcard to a Pi Zero, skip to the Design section.   Finished result   WSPRpi For people interested in the use in the WSPRpi project: The tw ...
Hi, I am 18 years old, callsign M0WUT and I have been constructing an amateur radio all band transceiver controlled by the Raspberry Pi. The progress on this will be detailed here on element14.   One of the main functions of the Raspberry Pi in this project is generating the frequency required to function as the Local Oscillator for this project. I had 4 main options to choose from and I will go through the pros and cons (in my opinion) of each method.   Method 1 The simplest way t ...
