Ham Member Lookups: 13685

 
 
 

Active contester and DXer since 1970.
Career in telcommunications as wireline/wireless sales engineer. Married with nine children+stepchildren

Member of Minnesota Wireless Association, Yankee Clipper Contest Club, Lake Vermillion DX Assoc. and Minnesota DX Club.

Built 90 ft (27m) tower with Christmas tree of 10-15-20/40 Yagis at parent's home in Northern Minnesota as teenager with double extended Zepp for 160m. At college I hung a long wire out my dorm window as well as became university ham club president to fund a club tribander on the science building. Married after college, spent 25 years on small lot in St. Paul, MN with HQ-1 mini-quad on a roof tower and stealth inverted L across street.

Moved to current QTH in 2008 and built 76 ft (23m) 45G tower with 2L 40m Moxon at 95 ft (29m), 10mHz rotatable dipole at 85 ft (26m), 4L SteppIR at 77 ft (24m) and 3L A3S fixed South at 35 ft (10m). Shunt fed tower for 160m, 2L phased verticals for 80m and three 225 ft (63m) Beverages.


The 40m antenna is a 2L Cushcraft XM-240 that I converted on a YCCC project to a W6NL 2L Moxon, replacing the loading coils with capacitive T bars. Result: flat SWR across the band - good gain and F/B. That's at 95'. Underneath that is a 4L SteppIR at 77'. Since the picture was taken, I've added a Hy-Gain loaded rotatable dipole for 30M between the antennas parallel to the booms so I don't get much interaction.

80M 4 square with a Comtek phasing box in the back yard with wire verticals and I'm very pleased with its performance.  Lots of radial wire yet to be installed!

In 1980 I visited W0AIH and saw his design for a unique "upside down" prop pitch which keeps the moisture out of the seals. I finally built one myself in 2010. The whole prop pitch rotates while the prop pitch gear is stationary, necessitating a power and control umbilical. A steel "top hat" is pinned to the case of the prop pitch. The bevel gear on top of the assembly is out of the differential of a Chevy S-10, and the Chevy axle is welded to a 2" x 22' DOM steel mast. Needless to say, I don't worry about torque or mast slippage.

The shack consists of a Flex 6500 with  Kenwood TS-590, an Alpha 78 no-tune amp. I've replaced the 3CX-400s with a pair of 3CPX-800s which is a great low cost, instant (manual)band-switching amplifier.

I'm using a Green Heron RT-21PP K7NV prop pitch controller plus the new SteppIR controller both connected to the computer. A second K7NV prop pitch and RT-21PP controller have recently been added to rotate the 40' RTS tower extension at 66'.  By slaving the Green Herons, the top SteppIR and 40M Moxon can remain stationary while the tower rotates.

I've always enjoyed FM BCB DX, and am using a Sony XDR-F1HD with an omni antenna at 65'.

I have three 225 ft (69m) Beverages that are switched to select either the RX antenna input on the TS-590, or a SoftRock that I use to BCB DX.

Just installed a YCCC Rx 5 square for 160/80M which is a high impedence design, 60' from the center element to each of the 4 corner elements to get ready for the low end of the sunspot cycle.   A 3L KLM 30M monobander to replace the current rotatable dipole at 85' is the final project for the 2106 season.

Thanks for visiting!
