Phil W1PJE’s Amazing MIT SolderSmoke Direct Conversion Receiver

We are really pleased to see that Phil W1PJE has completed his direct conversion receiver and has thus joined the Hall of Fame. Congratulations Phil.

We are shamelessly calling this the “MIT receiver.” But the truth is that Phil’s job at MIT was not part of this project, and in fact distracted him from his radio building efforts. 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.

Hi Bill and Dean,

After a long hiatus (and a restrung antenna), I’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’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… hmm.

Thanks for the fun and reminding me of a time when I was an undergrad at the EE bench. Modifications are next when I can find a few minutes.

  1. You are all way too kind. Don’t look too hard at my breadboard compared to W2AEW’s work of art! Thanks to this great community for the motivation.
