1296 MHZ EME

Under Construction

  QRP Station:

  Construction is underway to install 1296-MHz equipment on the 2.4 meter dish.  This will be a 
  temporary set up until summer when the radome will be removed from the dish and hardline
  can be acquired.
  
  Until then 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 LMR-400 coax
  to the dish.

  Attempts to access the dish computer control system using Hyperterm were unsuccessful.  
  It appears that the az-el-pol drives are selsyn motors so an attempt to drive them directly is
  the next step.  Without use of the cpu, circuitry will be needed to read the angle encoders.

  Here is the 1296 MHz EME Station Layout:




























  Spring 2007 - Update:

  Approximately 214-feet of 1-5/8 Heliax was picked from Chris, KL7FB, for 
  future use with the 1296 MHz EME station.





















  Summer 2008 - Update:









































  1296/1420 MHz septum feed will be 
  installed on the 4.9m dish instead of 
  the 2.4m dish.  The dish mount permits  
  az-movement from 40 to 280 degrees,
  and elevation from -10 to +90 degrees.
  
  QRP plans mentioned above will likely
  be the first EME operation on this dish
  using 1296 MHz.  QRO will follow as 
  soon as the GI-7b amplifier and
  water-cooling system is ready.
