Every once in a while, it's a good idea to step back and consider the big picture.

Fabio's Direct Conversion Receiver

Fabio, IK0IXI, is an electronic wizard from Civitavecchia, near Rome.   Check out his very nice DC receiver. Note that wonderful direct conversion sound.   Very cool that has it atop our beloved SPRAT.   Below you can hear the effectiveness of the audio filter.   Bravo Fabio!

A Ham Radio HackerSpace

Bill -  Enjoyed your conversation regarding seeing the Maker guys at a recent hamfest.  Thought I'd let you know that, at least on a small scale, we've created a ham hacker space in our club by organizing a "Builders Group" as an adjunct to the Williamsburg Amateur Radio Club (WAARC) here in Williamsburg, VA.  I volunteered my QTH as a meeting place and the majority of projects have been either QRP or test equipment related.  Folks select their own project and bring their own tools to use.  These projects have included the Hendricks tri-band QRP transceiver, NorCal FCC-1 frequency counter, N3ZI digital dial, Tuna Tin II transmitter and others.

I corralled two friends in the club to act as "mentors" to assist less experienced builders with soldering and construction.  Once builders complete their projects my workbench upstairs is available to verify correct operation or troubleshooting as required.

Here are a couple of pix of the guys having fun melting solder.
