   Description of Home Station:
 
   The 2m station consists of the Elecraft K3/10 and the Downeast Microwave L144-28HP-DRX 
   50w transverter. A RFC 2-317 linear amplifier provides 150 watts.

   The alternative VHF radio is the new Elecraft KX3 with HF-6m all-mode capabilities.  
   The KX3 will drive a DEMI 144-28LP 2.5-4w transverter and feed a Mirage B108 amplifier 
   running 25-35w on 144-MHz.  DEMI will soon have a PLL for VHF transverters which will
   be installed in the 144-28LP to enable 144-148 MHz operation with a 28-30 MHz IF. 
   The PLL will switch the LO between 116 and 118 MHz.  

   A DEMI 222-28 25w transceiver kit was finished on Jan. 5 and 10mw drives the Securitor 
   150w amplifier to 125w watts.
  
   A DEMI L432-28 25w transverter kit has been ordered (Feb. 2012).  I am investigating the
   use of the new DEMI PLL to provide 432-434, 435-437 and 445-446 FM simplex operation.

   A GE-Ericcson TMX-915 modified by KL7FZ for use at 927.5 MHz FM with 13 watts 
   output or approx. 100w with a surplus Motorola amplifier installed at the top of the
   eme tower.
