Home Page of the Amateur Radio Operator Ned Stearns, AA7A


Here I am making repairs on a VHF array atop the main tower.  I have managed to maintain an effective VHF station in Phoenix for almost 40 years.


Operating with Robert, 3B9FR. We met while I was on a DXpedition to Rodriques Island in 1999 operating as 3B9R. 

One of my many ham radio passions is making contacts around the world by bouncing signals off the moon (EME). This is a view of my handmade 2m EME station.

Recently, I have taken to traveling to Africa in November every year in order to participate in the CQ Worldwide DX CW Contest with the VooDoo Contest Group. In 2005 and 2006, I operated with this contest group in the West African nation of Mali. Pictured with me on the left in the 2006 event are Vince Thompson (K5VT), Fred Handscombe (G4BWP), Mike Fulcher (KC7V), Roger Western (G3SXW), Lee Finkel (KY7M), John Warburton (G4IRN) and Robbie Ferguson (GM3YTS). In addition to participating in the CQWW DX contest event, we also travel throughout the country when we can and also participate in other specialized ham radio activities such as RTTY or EME. In 2006, we assembled a portable 2m EME station and made a number of contacts around the world to the delight of the VooDoo Contest team as well as some lucky 2m EME operators.
