1296 MHZ EME

Under Construction

  QRP Station:

  Construction is underway to install 1296-MHz equipment on the 4.9 meter dish.  The dish
  will be fitted with a septum feedhorn, two-stage LNA, 6 watt driver and
  60w solid-state power amplifier.  This will permit running  less expensive 1/2-inch hardline
  to the dish.
 
  Photos from Fall 2005 of the 2.4 meter dish with Septum Feedhorn installed (click to see larger image):

  Spring 2009 - Update:
 
  QRP plans using the 60w amplifier mentioned above will likely be the first 
  1296 MHz EME operation on the 4.9m dish.  I sold my GI-7b and TH-328 PA's to raise
  funds to purchase the 300w solid-state amplifier kit marketed by W6PQL.  
 
  Go to the new 1296 Amplifier Page for details and photo's documenting construction
  and testing of this kit.
 
 
  Summer 2010 - Update:
 
  The dish mount permits az-movement starting from 035-131, 132-236, and 237-330 degrees
  stepped in roughly 90-degree increments.  Elevation is from 0.5 to +88 degrees.  Awaiting
  delivery of new DEMI 1296-28 transverter (est. August 2010).  DEMI 1296-144 sold.

  A paper describing the construction of the dish was presented at the 2010 International 
  EME Conference in Dallas, Texas. (2.4 Mb pdf)
