CT1BOH / A deep dive for experienced users

Inside SKIMVALID: why this report was delivered

The incoming spot is delivered; the cache supplies evidence. SKIMVALID does not choose the loudest receiver or retrieve one winning old report. It tests whether CT1BOH classified this new report as Valid. Other conditions in the user’s filter must also pass.

These examples include actual live cache snapshots and the actual scan actions, not a reconstruction from Telnet output. A diagnostic-only ARC6.6.159 engine on NC7J-3 recorded a short fresh-cache example and then decisions near the end of a full 30-minute capture on October 9, 2026. Detailed recording for the longer observation began after 27 minutes of normal traffic, without clearing the cache again. Two simultaneous user connections used:

W3BES:   SET DX FILTER SKIMVALID AND SPOTTERCTY=K
W3BES-1: SET DX FILTER SKIMMER AND SPOTTERCTY=K

The user filter does not change the CT1BOH cache or the quality decision. Classification uses the node’s shared incoming-report history before each user’s delivery filter is evaluated.

Both connections used FILTER mode and output ON. The node’s quality decision was correlated with the report observed on each connection. All times below are UTC timestamps from the node.

1. N3GJ: the fresh-cache confirmation path

This first example comes from the initial short capture after the diagnostic restart. The mature-history examples below come from the later full 30-minute observation.

This incoming report was Valid. Observed on both user connections.

KD7EFG-#’s report was Unknown because there were no nearby cached reports. WA7LNW-#’s report found one earlier same-call report, so it also remained Unknown. Neither was sent to the SKIMVALID user. Both were nevertheless stored and became evidence for the next incoming report.

Cached report #1; received 1.788 seconds before the incoming report; frequency difference +0 Hz. Stored quality: Unknown. This exact entry was counted by the live scan.

Same-call match 2

Cached report #2; received 16.385 seconds before the incoming report; frequency difference +0 Hz. Stored quality: Unknown. This exact entry was counted by the live scan.

  1. Scan row 1: WA7LNW-# agrees on N3GJ at 14054.0 kHz. Match count becomes 1.
  2. Scan row 2: KD7EFG-# also agrees. Match count becomes 2.
  3. The algorithm sets WE9V-#’s incoming report to Valid and stops scanning.
  4. The receiver’s CTY matches K, so the complete user filter passes. WE9V-#’s report was observed on both connections.

Earlier evidence need not already be Valid. Both counted cache entries were Unknown. The incoming report gained the Valid classification from their agreement. The older Unknown reports were not retroactively delivered. WE9V’s 11 dB was also weaker than KD7EFG’s 13 dB; this was not a strongest-signal selection.

2. KE6SRN: the oldest evidence actually counted

This decision was recorded near the end of the full 30-minute capture, after the node had accumulated normal traffic for at least 27 minutes. The nearby cache contained 12 reports; its oldest entry was 15m 58.4s old.

The exact two witnesses were K5KHK-# and K1RA-4-#. The older of those two was 15m 54.8s old. The table below shows every entry actually examined before the algorithm reached Valid.

  1. Read the cache newest first; skip other calls for the reasons shown in the table.
  2. Count the first match at cache row 1 and the second at row 11.
  3. Set the incoming report to Valid and stop. Then apply the user’s complete delivery filter.

At the second same-call match, the incoming report became Valid and the scan stopped. The full filter then passed, and this exact incoming report was observed on both connections. Cache age is evidence of what was available; only the annotated witnesses caused this confirmation.

  1. Read the cache newest first; skip other calls for the reasons shown in the table.
  2. Count the first match at cache row 5 and the second at row 25.
  3. Set the incoming report to Valid and stop. Then apply the user’s complete delivery filter.

At the second same-call match, the incoming report became Valid and the scan stopped. The full filter then passed, and this exact incoming report was observed on both connections. Cache age is evidence of what was available; only the annotated witnesses caused this confirmation.

5. K5NJR/B: the competing-call path

Node received UTCDX callReceiverkHzNew qualityUser delivery
17:57:21.834K5NJR/BW1NT-6-#28224.6BustedOnly the broader user feed: SKIMVALID rejected

This decision was recorded near the end of the full 30-minute capture, after the node had accumulated normal traffic for at least 27 minutes. The nearby cache contained 7 reports; its oldest entry was 22m 54.7s old.

The scan encountered the competing Valid call K5GJR/B before normal confirmation completed. Its recorded steps show why this incoming report did not satisfy SKIMVALID.

  1. Skip the first entry; its different call is too far away for the competing-call test.
  2. The next entry is a nearby, similar, already Valid call; enter the busted-call check.
  3. The neighborhood contains no earlier reports of the incoming call. The resulting Busted classification fails SKIMVALID.

The broader connection received this report, but the SKIMVALID connection did not. The diagnostic directly records the competing-call branch and the final Busted result. The full snapshot also lets us verify that zero recent cached reports support K5NJR/B. The secondary corroboration loop checks those call names; nonmatching secondary visits were not individually logged by this diagnostic. “Not examined” in the downloaded record refers to absence of a primary-scan visit after the competing call was encountered.

The orange row marks the competing Valid call. This is the algorithm’s classification, not independent proof of which callsign was on the air.

Same-call match 2

Cached report #2; received 7.722 seconds before the incoming report; frequency difference -200 Hz. Stored quality: Unknown. This exact entry was counted by the live scan.

The live scan counted WS2C-# first, then MM0ZBH-#, and classified OK2PMU-#’s report as Valid. However, OK2PMU-#’s CTY was OK, so SPOTTERCTY=K failed. Its report was absent from both user connections. The diagnostic made this otherwise invisible decision available.

WS2C-#’s Unknown report was visible on the broad connection because its receiver matched K. It was absent from the SKIMVALID connection because its quality had not yet become Valid. These are two different reasons a report can be excluded.

The complete CT1BOH decision path

How far back does it look? The current scan stops at 27 minutes of report age, while minute-based maintenance normally removes reports aged 26 minutes or more. This is a roughly half-hour evidence window, not a requirement to wait 30 minutes before a callsign can become Valid. A decision may need only two recent matches even when much older reports remain in the cache.

The examples above use the normal same-call confirmation path. Here is how the other branches fit around it.

  1. Select the band and nearby cache. Convert the incoming frequency to Hz and locate its 100 Hz bin. Collect that bin and three bins on either side, bounded by the band’s cache range. This is a seven-bin neighborhood, not an exact ±300 Hz test. Sort its reports newest first.
  2. Apply the age limit. The scan stops when a prior report is at least 27 minutes old. Periodic maintenance normally removes reports aged 26 minutes or more. Only reports still present in this node’s memory can provide evidence.
  3. Count exact callsign matches. A prior report with the same DX callsign increments the match count, regardless of its stored quality. On the second match the incoming report becomes Valid and scanning stops. This counts reports, not distinct receiver callsigns; UNIQUE is a separate filter field.
  4. Check a competing callsign. For a different call, first require a prior Valid flag and a frequency difference strictly less than 110 Hz. Then require callsign similarity greater than 50%. Similarity is 100 minus the integer percentage edit distance, measured against the longer callsign. If these conditions fail, skip that entry and continue scanning.
  5. Resolve a possible busted call. If that competing-call check is reached before the normal second match, search the same recent neighborhood for two reports supporting the incoming call. Fewer than two gives Busted. Two gives BustedOverride, which is exposed to user filters as Unknown, not Valid. The earlier competing call is retained as the reference. Scan order therefore matters: two same-call matches reached first establish Valid; a qualifying competing call reached first takes this branch.
  6. Recognize possible QSY. If quality is still Unknown and the call is in the band’s recent validated-call memory, change it to QSY. BustedOverride is a separate internal result and is not changed to QSY by this check. The Valid memory is refreshed on successful validation; a validated move greater than 400 Hz also removes that call’s old neighborhood reports.
  7. Store the result and distribute. Store the incoming report with its assigned quality. Map Valid to SKIMVALID, QSY to SKIMQSY, Busted to SKIMBUSTED, and Unknown / BustedOverride to SKIMUNKNOWN. Evaluate the user’s full filter and normal output/delivery conditions. A cached report is evidence, not a delayed delivery candidate.

CT1BOH applies to CW / RTTY RBN skimmer reports. Human reports and FT Modes reports do not receive these quality classifications. Valid means this algorithm found corroboration; it does not guarantee a correct decode.

Evidence and credits

The full nearby cache, stored quality flags and executed scan actions were captured inside the live node for each selected decision. All published snapshots are complete and untruncated. The green reports were independently observed on both user feeds; the non-K IK4HLO report was excluded from both.

Mature-cache XML records are linked beneath each example. For the initial short-capture records: N3GJ / WE9V trace, and IK4HLO / OK2PMU trace. These contain spot data and decision evidence only.
