KW7 March 21, 2007 ETN2 Peter Cozzi Hi Roger, The KW7 was originally a jeep mounted unit. The little wire thingy block was the original way to rewire the patch-board every day. Then came the IBM punch cards and it's attendant reader door on the unit. The IBM card really cut down on the maintenance as all I had to do was clean the reader contacts. I remember the big 20 channel reel to reel recorder and also working on the receiver switch matrix ( which had real, discrete, transistor flip flop circuits for each channel! ) :-) Anyway, nowadays the antenna assignment computer and matrixes probably fit into one 19" rack and the printers are probably off-the-shelf lasers. In the future it will be ethernet-centric with the operator using a simple web browser. Anyway.. Thanks for getting back to me....:-) Regards Peter "Did We Really Do Station Electronic Stock Without a Computer?" Cozzi webmaster note: Peter started out, as he says, as "a deckie on the Cutter Mellon" and then put in for Electronics school on Governors Island, New York. Peter did well there, becoming class leader and high up on the list for his choice of billets. He then chose crypto school, at Mare Island, and then went to NMC, at Point Reyes, where he earned his ETN2. About NMC San Francisco, Peter told me, "Well it was a lot of fun being stationed up there. It's unfortunate that Homeland security precludes a casual visit to the station." - Roger J.
