Ham Member Lookups: 11718

 
 
 

Active contester and DXer since 1970.
Career in telcommunications as wireline/wireless and now as wide area Ethernet sales engineer for large USA CATV firm. Married with nine children+stepchildren

Member of Minnesota Wireless Association, Yankee Clipper Contest Club 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.

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 Kenwood TS-590, an Alpha 78 no-tune amp that I probably bought the parts for in 1979 when I worked in Colorado for ETO as a materials manager. I've replaced the 3CX-400s with a pair of 3CPX-800s. Full output on all bands, instant (manual)band-switching.

I'm using a Green Heron RT-21PP K7NV prop pitch controller plus the new SteppIR controller both connected to the computer.

I've always enjoyed FM BCB DX, and am using a Sony XDR-F1HD. I had an 8L Winegard FM BCB Yagi on the mast before I put up the 30M dipole but it always seemed strange to have to turn 300# (136 kg) of antennas and mast to listen to regional FM BCB stations!

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.

Thanks for visiting!

73,
