My Heathkit, and other AC clocks have been broken for months now. I started a project to figure out how bad it was. It's getting interesting as I am approaching my goal of coding a software emulation of an AC line clock. During the process I developed a couple of web pages to help me understand the problem better. Frequency meter: http://wa6rzw.homelinux.net/addon/grid/gauge/hertz.html
Grid history graph: http://wa6rzw.homelinux.net/addon/grid/graph/wgraph_1.html The meter requires a real HTML5 browser, anything but MSIE. When I started this my goal was to provide an external reference source to the Heathkit CG-1005, so that it will keep correct time. Since I began I have considered a number of hardware solutions to correct or modify the Heathkit. I think I am dragging my feet because there are no replacement clock chips (in case of disaster,) to be found for this model. At the moment I am thinking about modifying a DC-AC inverter and syncing it to an audio oscillator, (don't laugh, my Heathkit 30 year old audio generator is way better, more stable, than the grid). 73, Ed - WA6RZW _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
