Old Buzzard George - W1GAC

George Mouridian passed away in 2007 at the age of 91 but had been an active ham for over 70 years and while he did us... READ MORE |

The Deltronic CD-144A

One of the most asked questions is, “What kind of microphone should I use? ”It all seems very confusing: Dynamic, Condenser, Ribbon, Electret, Large Diaphragm,Cardioid, Omni—so many technical words!

Paul (WA6CJC) and Ed Heyman (WA6EOA) were ham buddies who met at Alexander Hamilton High School on the west side of Los Angeles in the 1950s. They got the idea to do something interesting and unique involving radio and lamented the fact that they weren't old enough to drive and didn't have a car to go mobile in.
