I go by "Shel" on the air.

Originally licensed in 1965 in NY, I've lived and operated as KF0UR in Colorado Springs, CO since 1991.

I am mostly an HF operator and enjoy DXing, contesting, and ragchewing using CW, SSB, RTTY, FT8, and PSK31. My rig at home is an Elecraft K3 and either a W5GI Mystery Antenna or a multiband dipole. I'm also on 6 meters whenever I find the band open.

At 6850 feet (2088 Meters) above sea level at the base of the Rocky Mountains, my wire antennas do reasonably well going east and south in our antenna restricted neighborhood, as we are high above the surrounding terrain, and have a clear view of the eastern horizon (see picture below). Going west, the Rockies are less than 1 mile ( 2 km) away, and rise another 2500 feet to 9433 feet (2875 meters), which makes QSOs to the west more challenging (but not impossible!).

For 6 meters, I have a stressed Moxon hanging on an upside down rotor under the deck. It's painted the color of the deck and is pretty stealth (pictures below).

I also enjoy QRP hiking quite a bit. My portable setup is an Elecraft KX3, SideKar, a homebrew (very) portable vertical, and a small LiFePo4 battery. I also made a portable homebrew 6 meter Moxon. The Adventure Radio Society's "Flight of the Bumblebees" contest mid-summer is my favorite QRP hiking event.

And speaking of QRP and operating portable, Steve KB3SII, another QRP enthusiast, and I are in partnership in QRPworks LLC, which produces a number of neat QRP accessories:

QRPworks SideKar, SideKar Plus, K-Board

QRPworks has created a number of innovations for portable and home operations. 

The SideKar, SideKar-Plus and K-Board are ideal for the Elecraft KX2, KX3, and K3/K3S.

Physically, the SideKar (40 character display) and SideKar Plus (80 character display) mount on the right side of the KX3 and on top of the KX2 in seconds.  Or sit on a desktop.  They have the same features such as sunlight readability, sending 20 CW/PSK31/RTTY messages, logging 1000 QSOs with ADIF file export, Field Day logging, Summits on the Air logging, contest features, freezing/scrolling back the text received, and more.

The K-Board is great to add a wireless or wired keyboard to your KX2, KX3, or K3/K3S top send with a keyboard or send 200 user-defined messages.  

Check them out at www.QRPworks.com and download the full manual to see all the features.


Key Log Go

The Key Log Go is ideal for the Yaesu FT-817.

While the SideKar family is KX2/KX3/K3 centric, the KLG can be used with all rigs, with special features for the FT-817 and KX2/KX3. It has a WinKeyer built in that can key any rig, while offering the logging, SOTA, messaging, and contest features.

Plus you can enter data using your paddle in addition to a keyboard, so you can leave the keyboard at home and still log, create/edit messages, edit SOTA refs., etc.

The Key Log Go manual is also available at  www.QRPworks.com.


QRP hiking early morning up on Mt.Herman, CO (9000 feet, 2743 meters), above the clouds, with my KX1 and 12 foot (4 meter) homebrew vertical (collapses to 1 foot):


Same morning as above, but the a little later as the clouds were clearing. That's the 12 foot ( 4 meter) homebrew vertical mentioned above against at FB view of the clouds. Activating National Parks on the Air (NPOTA) "MN28" with a KX3 and a SideKar for message sending and logging, homebrew vertical, and a Bioenno Power 6 amp LiFePo4 battery (blue thing).


Up on the side of Mt. Blodgett at 8000 feet (2438 meters), near my QTH:


The FB view from Mt. Blodgett, looking east:



QRP setup: Elecraft KX3 and QRPworks Key Log Go, Palm Mini-Paddle, and Watt's Up meter (blue thing).    



QRP set up on Iron Mountain, Manitou Springs, Colorado. The KX3 and Key Log Go's feet fit nicely on the back edge of the rock.


The vertical's view on Iron Mountain. Looking east over Colorado Springs.   The tallest mountain in the distance is Pikes Peak (14116 feet).



When I used a Gel Cel for power, I used a PowerFilm Solar 10 Watt folding solar panel to keep the battery topped off all day. It's lightweight and stores easily in the backpack.  I've now switched to using a LiFePo4 battery from Bioenno Power.  



The shack at home: Elecraft K3 & P3:


Looking east from my shack window, which is on the lowest level of the house. That's the eastern horizon you (and the antennas) see. They do well in that direction. The structure is a wooden deck on the back of the house. The antennas are very high above average terrain, which helps a lot. It's also a FB view while I'm operating.


Here is the 6 meter Stressed Moxon underneath the same deck, looking east. The end of the Alpha Delta DX-EE multiband diploe is visible above the Moxon. The Moxon is 10 feet (3 meters) above the ground, but much higher above average terrain, as you can see. The road below is about 100 feet lower.


And here's a shot of how it's mounted, on an upside down rotor mounted to the deck. I can point it from 0 to 180 degrees. If I point it west though, it points directly into the house 10 feet away, which is not too helpful.
