  Update for FEB. - 2012
 
  The Elecraft K3/10 12w HF transceiver has replaced the FT-847 on HF bands.
  A CCI 300w HF solid-state linear amplifier kit has been built.  It runs up to 
  270w with the drive available from the K3/10.

  I operate using either an 80-40m dipole or the TH3-mk4 Tri-band yagi (20-15-10m).  
  On November 25, 2008 the second 50-foot Tower was raised supporting my Tri-band yagi and 
  the 80-40m inverted vee dipole and a 30m sloper diplole.
 
  I occasionally operate on 20m PSK-31 and sometimes check into the 14.345 MHz weekend EME Net at
  1700 utc.   On 80m I occasionally check into the following Nets:
    

  • On 3933 KHz, the Motley Group on week nights at 2100 local time.
    • 

  • On 3920 KHz, the Swap-N-Shop Net on Saturday mornings at 1000 local time.

  The layout of the two 50-foot towers are well situated to support a 
  130 foot horizontal wire at 40-50 feet above ground.  This has been installed as an inverted-L
  43 feet high by 130-feet long (see 600 meter page).
 
  The HF Tower supports a dual-band inverted vee at right angles to the Inv-L.

  New J-Pole for 6m/10m Installed
 
  A combination J-Pole vertical antenna has been set up to permit working 6m and 10m FM stations.
