6EQUJ5 -- SNR, the Big Ear Radio Telescope, and the "Wow" Signal


This Hack-A-Day article explains the significance of 6EQUJ5 on the paper readout of the Big Ear radio telescope.  It is a signal-to-noise readout. 

The article also has interesting information about the radio telescope that was used.  

I have on my shelf John Kraus W8JK's wonderful book "Big Ear Two -- Listening for Other Worlds."  John Kraus is the guy who built the Big Ear.  In a reminder of how new radio technology really is,  Kraus got his start in radio as a ten year-old boy in 1920.  He ripped the wire out of the ignition coil  of a Model T Ford to make a tuning coil for a crystal radio.  He took the earpiece out of the family telephone.  His father gave him a chunk of Galena.  He used the crystal radio to listen to the early broadcasts of WWJ in Detroit.

  1. My Elmer Bob Scott WB8JEY lived down the road from the Big Ear stopped and had a look more than a few times very impressive for a 19 year old. Got to listen to Bob Kruse talk at COSI super interesting.
