Current Projects at K4JA
Paul always has a lot of projects going on.
It is interesting to see which one he is working on!
- Put up a new 40M tower and antennas
- The 40M tower came crashing down due to Tropical Storm Isabel. More details available here.
Paul is trying to determine what to put in its place. He's currently thinking about a 3-high stack
of full-size 3-element 40M yagis, stretching up to 200 feet.
To be completed Spring 2004?
- Beverages
- No receive antennas were used in 2002-2003 season. Will try to fight dense woods to locate a phased
array to EU in Fall 2003. (Note: phased pennants or Beverages still thinking woods is tuff to work
in especially in the summer heat, Bugs and poison ivy etc). The hurricane ruined the 40M tower and
antennas, pushing this project to the back burner.
To be completed Fall 2004
- 40M Full-size 4 element multiplier antenna
- Build full-size 4-element 40M yagi and put at 140 feet. Will be used in place of
Cushcraft 2-el.
Completed September 2003
- 80M Full-size 9 element circle array
- A 9-element array was constructed and erected. This antenna was designed by John Brosnahan, W0UN
and featured in the ON4UN Low Band DXing book. K9DX also helped Paul out, as he previously built a
160M 9-circle. Gain
is good, but still working on
Front-to-Back. K9DX came out to help and greatly improved the F/B.
Completed Fall 2003
- Station Automation
- Added 3rd Acom 2000A and introduce MO3R switching (Muti-OP-3-Radio). This will allow any one of three
radio's on any band, any antenna.
Completed Fall 2003
- RF Switching
- Chad, WE9V, is designing a new switching system. It will control all the switching
combos for the main antenna system for each band. In addition, we will be able to
select from the Main antenna system, or two alternative antennas. Also have the
ability to select any combination of the three (main, alt 1, alt 2). One controller and one RF switch per band...lots of work.
Completed October 2001.
- South America fixed tower
- A 130 foot fixed tower with fixed monobanders for 10, 15, and two for 20M.
The top 20M is rotatable. The 10 and 15M yagis will be fixed towards South America.
Completed Sept 2001
- 80 meter four square
- Completed August 2001, working great.
- 160 meter four square
- Completed August 2001, working great.
