Mapping geocoded contest log data using node.js and openlayers. The goal was to make something that looks like the Reverse Beacon Network map, only for contest log files. I use RBN for testing antennas now. That map display gives you a pretty good idea of your actual antenna pattern. Code is written in node.js (javascript) …
Work in progress… An html example that sends and receives CAT commands with an Elecraft K4 connected to the serial port of the machine running the web browser. The file was built using examples from this article by Francois Beaufort. https://developer.chrome.com/docs/capabilities/serial It’s an excellent resource for Web Serial. The html file for this project is here: …

Another working prototype with Max and CubicSDR Now working some better… The Max SDR patch is receiving an IQ audio stream at 96 KHz from CubicSDR and sending frequency data to rigctld daemon via a python script that recodes OSC to tcp data. repository: https://github.com/tkzic/max8radio Files: max8sdr1.maxpat py3rigctl2.py (python script) Instructions: Basically the same as instructions …
New version of software define radio for Max/MSP (in progress) github repository: https://github.com/tkzic/max8radio Notes goals and strategy The new approach will be to remove most of the device handling code from Max. Instead providing device interfaces from existing device libraries, like soapy-sdr, hamlib, gnu-radio, etc., The Max portion of the project will read IQ files, perform …
Sampled shortwave signals
under construction… Max/MSP features a full implementation of SQLite using the js (javascript) object. Here we describe a database to track radio frequencies. Frequencies are stored by time, type, and mode. The frequencies can be retrieved in various ways, like with a scanner radio. Tables can be created and maintained outside of Max using the …

Mac OS software for Softrock SDR receiver By DL2SDR Download from: https://dl2sdr.homepage.t-online.de/ Use with “Softrock USB-Controller app: https://reactivemusic.net/?p=18285 Note: After some experimentation with various audio interfaces and sample rates, I found it difficult to get clear audio on higher sample rates, like 192k and also there doesn’t seem to be any way to adjust the IQ balance.
