Adrien, VE3IAC shows me ClearDarkSky.com

February 8, 2009 | Astronomy | By: Mark VandeWettering

While reading up on Adrien’s blog, he mentioned a site which I hadn’t seen before. It attempts to predict how good the conditions will be for astrononomy and astrophotography for locations around North America. For instance, I teach (well, more properly used to teach, since I’ve been enormously busy lately) telescope making at the Chabot […]

VK6DI spots my MEPT beacon…

I just got mail from David, VK6DI. He’s reported spots of my WSPR beacon a few times in the last few days, and I’ve been trying to see if his grabber shows my MEPT beacon (the MV”). He sent me an email today, with the following screen grab: Yep, that’s my beacon. Running an output […]

Adding a buffer amplifier to my crystal oscillator…

February 8, 2009 | Amateur Radio | By: Mark VandeWettering

Today, I felt some compulsion to work on something radio related. A couple of weeks ago I build the crystal oscillator from Chapter 1 of Experimental Methods in Radio Frequency Design. I was lacking the necessary toroid to continue building the buffer amplifier, so I had ordered some from Doug Hendricks at qrpkits.com. They arrived […]
