There was, however, one moment in which Phil had sent us a video of his receiver in progress. There was some audible fan noise in the background. Phil apologized, noting that the noise came from a nearby receiver that monitors upper atmosphere winds using meteors. Now that, my friends, is some cool MIT stuff. <\/b><\/p>\n<p><b>Phil writes: <\/b><\/p>\n<div><i><b>Hi Bill and Dean,<\/b><\/i><\/div>\n<div><i><b><br \/><\/b><\/i><\/div>\n<div><i><b> After a long hiatus (and a restrung antenna), I&#8217;m happy to report the Soldersmoke DC receiver is finally done and working well. The relatively long video above shows a tour from CW to SSB to AM to digital telemetry to time signal (CHU at 7.850 MHz). A bonus frequency counter was included to show the viewers where I was in the band. It&#8217;s not pretty but it works. I need to slow down the tuning but that is a future job. Sorry for the serious wobbly attempts to zero beat the AM carriers but I can fix that later&#8230; hmm.<\/b><\/i><\/div>\n<div><i><b><br \/><\/b><\/i><\/div>\n<div><i><b> Thanks for the fun and reminding me of a time when I was an undergrad at the EE bench.
