Primary session result

What did this run show?

Run details N1RWJ · FN41fr · General coverage · 20 m · tx path; Transmit-focused

General coverage goal: Prioritizes shared-path signal, common listening opportunities, observed reach, distance and bearing, and repeatability. No universal antenna winner is selected.

The recorded goal changes presentation priority only; evidence and calculations are unchanged.

Available

+5 dB

Median signal difference on the same remote paths

On remote paths heard with both antennas, DX Commander's median received signal was 5 dB higher than Attic EFHW's during this recorded run.

83 shared paths · 327 matched observations · 7 alternating blocks

Other evidence, kept separate

These numbers answer different questions and do not change the dB result above.

What these results compare
Same-path signal
Signal reports from remote paths heard with both antennas within the same eligible alternating block and test condition.
Same active receivers
Detection outcomes only for receivers confirmed active during both antenna cycles in an eligible block.
All observed paths
Every unique recorded remote path per antenna, including paths without a confirmed listening opportunity in both cycles.

These populations are not interchangeable. Missing public evidence is not a zero-strength measurement, and this recorded run does not establish a universal antenna ranking.

Shared-path signal

Signed values: Positive values mean DX Commander was stronger; negative values mean Attic EFHW was stronger. The vertical reference is zero.

Test condition: TX path · 20 m · WSPR · Imported spot · WSPR.live (delayed/public)

Each remote path contributes one median regardless of its paired-observation count. Full evidence retains the exact paths, per-path medians, and block-level audit rows.

Observed paths

These are uncontrolled unique-path counts. They do not establish that the same receivers were listening in both antenna cycles, and an observed-only path is not a controlled non-detection.
