KD3ANN’s clear advantage lies in reaching a substantially larger set of unique receivers, with the differential heavily weighted toward mid-range and long-haul paths, particularly westbound into the Pacific and across the continental United States. The stations share nearly identical power levels and geographic coverage metrics, but KD3ANN uniquely activated more than four times as many receivers as N2LQH missed it, and those receivers skew strongly westward and sit at noticeably greater distances. This pattern suggests KD3ANN is operating an antenna with a lower takeoff angle and stronger gain on the horizon, likely a higher or better-sited horizontal radiator, while N2LQH’s unique receivers cluster closer to home at shorter median range, hinting at a modestly higher angle of radiation that favors NVIS and regional propagation at the expense of skip distance. The higher DX ratio achieved by N2LQH despite fewer total spots reinforces that its antenna is comparatively inefficient at working the dense mid-tier population between regional and true DX range. N2LQH’s operator should experiment with raising the antenna or switching to a configuration that lowers the primary lobe, such as a center-fed dipole at a half-wavelength or higher, and consider increasing on-air time to match KD3ANN’s duty cycle, which alone would close part of the unique-receiver gap.

N2LQH’s exclusive reach into a large and balanced set of European and North American receivers—distributed almost equally between eastern and western compass quadrants—indicates a horizontally omnidirectional antenna with a low takeoff angle capable of consistent DX skip. The median distance of these unique contacts sits squarely in the multi-hop skip zone, suggesting excellent low-angle radiation efficiency. In contrast, NW2W’s unique receivers skew heavily westward and include a higher proportion of closer North American stations, implying either a modest westward pattern bias or a slightly higher average takeoff angle that favors mid-range propagation over the most distant European paths. The much larger total spot count for N2LQH reflects triple the on-air time rather than a fundamental performance gap, but the directional asymmetry and the fact that NW2W reached very few unique European receivers suggest its antenna may not be optimized for the critical low-angle eastbound launch required on 30 meters. NW2W’s operator should experiment with raising the antenna or adding radials if using a vertical, or lowering a horizontal dipole if it’s currently too high and producing a steeper lobe, then compare European reception during morning grayline openings to verify any improvement in low-angle eastward radiation.

KD3ANN’s dominant advantage lies in sheer coverage breadth rather than distance capability: the station uniquely heard more than twice as many receivers as N2LQH missed, with the差分 heavily weighted toward North America and Europe in roughly equal proportions across western and eastern quadrants. This suggests KD3ANN benefits from either more favorable takeoff angles that fill mid-distance skip zones or simply more time on the air—the five additional days of operation translate directly into filling gaps in sporadic openings that N2LQH’s part-time schedule missed. N2LQH’s unique receivers show a similar geographic spread but smaller absolute count, indicating comparable antenna performance when actually transmitting; the slightly higher DX ratio and miles-per-watt efficiency confirm the antenna itself is competitive. The lack of strong directional asymmetry in either station’s unique-receiver set argues against a major pattern deficiency at N2LQH—both are working all compass points with similar median distances—pointing instead to duty-cycle as the limiting factor. N2LQH’s operator should prioritize increasing days on air toward KD3ANN’s near-full-month schedule, as the existing antenna system demonstrates it can match the top performer’s per-transmission effectiveness when given comparable exposure to varying propagation conditions.

KD3ANN’s unique receiver set is heavily concentrated to the west and relatively nearby, suggesting a lower-angle radiation pattern that favors shorter domestic and Caribbean paths, while N2LQH uniquely reaches significantly more distant European stations to the east. This directional asymmetry indicates KD3ANN likely benefits from a lower takeoff angle optimized for skip propagation into the western hemisphere, whereas N2LQH appears to have either a higher mounting or an antenna configuration that favors the longer trans-Atlantic path but sacrifices some western domestic coverage. The fact that N2LQH’s unique receivers are both more distant on average and heavily skewed eastward, yet KD3ANN still leads in total activity despite fewer days on air, suggests KD3ANN’s antenna is better optimized for the typical daytime 15-meter openings that favor mid-range propagation in multiple directions. N2LQH’s higher DX ratio and Europe fraction confirm strong long-haul performance but hint at a narrower azimuthal sweet spot. To improve all-around performance, the N2LQH operator should investigate whether lowering antenna height slightly or adjusting the radiation angle could recapture westward mid-range propagation without sacrificing the existing European strength.

N2LQH’s dominant advantage lies in short-to-medium range North American coverage, evidenced by the large cluster of receivers it uniquely worked concentrated in the western and northern quadrants at relatively close distances. This pattern strongly suggests a lower takeoff angle and better azimuthal distribution, likely from a higher or better-sited antenna that efficiently radiates into the domestic skip zone while maintaining competitive long-haul performance. KC2GYU’s uniquely-heard receivers are fewer but skew heavily toward distant stations, particularly in Europe, with much greater median distance, indicating the station is punching through on long-path DX despite operating at significantly lower power but struggling with regional and mid-range propagation. The directional coverage gap and the short-range deficit point to either a compromise vertical with high-angle radiation that favors NVIS and extreme DX over intermediate hops, or a receiving environment with local noise that masks weaker mid-distance signals while the station’s own transmissions still escape efficiently. KC2GYU should experiment with raising antenna height or adding radials to suppress high-angle radiation, which would likely improve fill-in coverage across the western and northern domestic sectors without sacrificing the impressive long-haul efficiency already demonstrated.
