First of all, I’m thankful that my parents encouraged me when I took up radio as a hobby (or at least looked the other way when I did some of the crazy things [...]

Last weekend, I took my laptop to the Hands-On Museum, with the idea of perhaps trying to work some PSK 31. I’d downloaded and installed CocoaModem, a freeware package for the Mac, and I brought along the Buxcom Rascal interface that I purchased several months ago. I didn’t’ have a USB-RS232 adapter, but I guessed [...]

Do you have a small CRT in your junk box? Then, make an oscilloscope! Just be careful with the high voltage supply.

I was getting a little concerned. I hadn’t worked any stations whose callsigns spell words in quite a while, but about a month ago I got back on track. Since then, I’ve worked:

WB4DAD
K3IF
K2SIT
