Re: [IRCA] Cape Lookout Oregon non-DX Overview - Oct. 31-Nov. 2

[Guy Atkins <dx@xxxxxxxxxxxxx>]

Hi Nick,

The conclusions were inconclusive, LOL!

The bulk of the so-called experiments involved observing phasing results
with close spacing (approx. 70 feet between antennas). Andrew Ikin of
Wellbrook has said repeatedly to me and Dave that his phaser design
requires a minimum of 40 meters spacing to work effectively. However, Dave
had the Quantum Phaser along, and he knew we could get *some* results at
closer spacing but with a limited bandwidth. We did not have a Wellbrook
phasing unit with us this trip.

Dave found that he could indeed get decent nulls (loop vs loop, or loop vs
vertical) at 70 feet, but unfortunately the desired DX signal strength
dropped along with the nulled station! That's the main takeaway that I
remember from our work, which granted wasn't very scientific. Too bad you
weren't along, Nick, as I know you'd keep us in line and help us reduce
variables and banish wishful thinking :^)

73,

Guy
