I've been a ham since 2005. I'm located near Allentown, Pennsylvania, USA. Grid FN20en.

My equipment is as follows:

  • Kenwood TS-590s Transceiver
  • ICOM 718 Transceiver
  • LGD AT-100 Pro II Antenna Tuner
  • Astron RS-35M Power Supply
  • K4KIO Hex Beam at 30 Feet
  • Home Brew 80-40 Fan Dipole at 30 feet
  • Hustler 6BTV Vertical Antenna (Ground Mounted with 60 radials)
  • Tigertronics Signalink USB PC to Rig Interface for Digital Modes
  • Heil Headset with Microphone.

I enjoy digital modes including PSK31, Olivia, Contestia and RTTY. I plan to try Phone Contacts now that I have my new Kenwood Rig. I enjoy learning more about Radio, Propagation, and Electronics in general. I like building kits, homebrewing and experimenting in general. I put together my first Surface Mount kit, a small Software Defined Receiver. Other hobbies include gardening, long walks with my faithfull dog, Fluffy, reading Science Fiction, and Business and Economics. I'm usually on the air a couple of times a week. I enjoy a good rag chew as well as quick DX contacts. May we meet on the air waves!

I reply electronically to QSL cards sent to me via eSQL.cc. I'll reply with my paper QSL Card to folks that send me their card via Direct or Bureau. No need to send postage. However, an address label or self addressed envelope is appreciated.

I have been happily married for 36+ years,have two adult sons and a dog. A special thanks to my wife for letting me indulge in my hobby.

My Station KB3MDT

  • Always a little cluttered, but lots of fun.
  • There are several home brew computers under the table.
  • My wife calls this room my Man Cave.



My K4KIO Hex Beam and my FAN Dipole

  • The Hex Beam is on a 4 1/2 foot aluminum tower from Glenn Martin.
  • I use a Yaesu G450A Rotor and GS-065 Thrust Bearing with a 5" Long 1.9" Diameter Aluminum Mast from OnlineMetals.com
  • The Fan Dipole currently has wires for 80M and 40M. I removed the 20M and 10M wires when I installed the Hex Beam to prevent distortion of the Hex Beam's pattern.




My Hustler 6BTV with Homebrew mods for 12 and 17 Meters

  • Its squeezed into my back yard and is surrounded by Power Lines, Wire Fence, and my House with Mylar coated "Blue Board" underneath Vinyl Siding.
  • I lost count after adding 60 ground radials. I even have radials laying on the ground in my Vegetable Garden that I move around as needed (so I don't cut them with the shovel).
  • The Antenna is guyed with rope above the 2nd trap, guys barely visible in the picture.
  • Note: I have since removed the 12 and 17 Meter modifications. I couldn't get the SWR down below 2.5 on 15 Meters with the 12 and 17 Meter modifications in place. I prefer using the Hustler without an Antenna Tuner.



Here is a closeup of the top of the Hustler 6BTV Showing the 12 and 17 Meter Mods

  • The horizontal additions are PVC Pipe held on with stainless steel U Clamps.
    • Don't use metal for these brackets as you don't want them as part of the antenna.
  • The springs above the insulators keep the proper tension on the 12 and 17 Meter Wires.
  • I used the formula 234 / Freq in MHz = Length of Wire in Feet as a starting point.
  • The length includes the 1 foot that is at the bottom of the antenna shown in the next picture.






Here is a picture of the Hustler Base with the Homebrew 12M and 17M Mods

  • The 12M and 17M wires are parallel to and about 1 foot away from the main mast.
  • The bottom brackets are 1" by 1/8" aluminum stock held to the mast with Stainless Steel U Bolts.
  • The brackets are electrically part of the antenna.
  • The 14 gauge wires are also electrically part of the antenna. They are fastened to the main mast via a stainless steel hose clamp.
  • The wires have insulation where they pass through the holes simply to protect them from fraying.
  • Some other details in the picture:
    • Choke Balun created with 20 foot of Coax and "half" of an old 5 Gallon pail as a form.
      • I rewound the Choke Balun on a 5" Diameter piece of PVC since this picture was taken. Some folks on eHam.Net suggested this would be more effective.
    • DX Engineering Tilt Base - Highly recommended as major labor saver!
    • Ground Radials terminated in upside down soda bottle to minimize corrosion on the connectors.
    • Tomato Cages in the background - no, not part of an antenna.






Aerial View of House

  • Red = Fan Dipole 80-40-20-10 Meters (Guy Ropes not shown)
  • Blue = Utility AC Power Lines
  • Yellow = Ground Mounted Hustler 6BTV Vertical 80-40-30-20-17-15-12-10 Meters

Note: This is before I installed my Hex Beam and removed the Fan Dipole 20M and 10M wires.





My wife Janet and I while on vacation

  • We rode the horses in the ocean a few minutes later.
  • It was lots of fun - I almost fell off the horse!



My faithful dog Fluffy.

  • She is often on the floor at my feet.
  • Fluffy is studying for her Technical License :-)


My QSL Card.

  • Send me one of your paper QSL cards if you would like one of mine!
  • No need to send me postage. However, an address sticker or addressed envelope is greatly appreciated.
