I used the K-3 Big Litz Dx Set for the Open Class. It was the same set up as last year.

For the Loop Class, I used a low Q loop built on cardboard box.

The Active Device Class entry was a WN6Q MPF-102 Regen (Via Owen Poole). I originally
tried this as a double tuned set using 2x 660/46 ferrite assisted air coils, 4 gang ceramic
wiperless variable caps, and a Litz air tickler. The regen set worked well, but was very hard to
line up and very touchy. When the antenna tank was removed the set worked MUCH better!
It still WAS a regen, and therefore still had a few flukes. It was MUCH more tamed, and
Dxing became much easier.

The sets radiation was read off of my Icom R-70, so digital spotting was a snap. The final
version was a single tuned tank of a ferrite assisted air coil, a 4 gang ceramic wiperless and
crystal earphones in parallel. The antenna was VERY lightly coupled via a few insulated turns
of a gimmick capacitor. At times, I could zero beat the set simply by turning my head a bit to
one side!

I copied SOMETHING ( anything from beat notes to ear splitting locals) on nearly EVERY
frequency out of the 119 channels. Maybe 90 stations or more of at least very weak audio
or better.

FWIW, I made a big boo-boo and left the set in place during a vicious white out snow squall.
We had very high winds and blizzard type of snowfall rates. The antenna kept discharging
arcs every 5 or 10 seconds. They could be heard in the next room. By the time I realized
what was going on, it was too late. I pulled the antenna line off and measured the arcs,
which by that time were down to around 3/4". To fry the set in the position it was in, they
had to have been at around TWO inches (30 Kv??) to bypass the gimmick cap twists and
leap to the set. Needless to say, a new FET had to be installed. Live and learn.

The set used was a Litz Special, modified to Dave Schmarder's #44 wiring configuration. The antenna was 250 feet long and 30 feet high. The ground consisted of two 8 foot ground rods. The set used an 1N34A diode and 4K Navy hadphones. No wave traps were used. The spotter radio was a Realistic DX-60 with a frequency counter. Continued on Page 4.
