W7PEN Activity

A kerchunk is a filtered quick keyup that is not closely associated with a longer transmission from the same source.

QSO-Interruptus is the percentage of that source's filtered kerchunks occurring within 12 minutes before or after any transmission of 3 seconds or longer, regardless of which source produced the longer transmission. It describes a timing pattern only; it does not identify the cause.



QSO Airtime Share compares that source's meaningful conversation airtime with the meaningful conversation airtime of the entire system during the selected timeline. Only transmissions 3 seconds or longer count toward QSO airtime; filtered kerchunks and 1-to-3-second transmissions do not count. This provides context for Share of Kerchunks by comparing actual repeater conversation use with short-keyup activity.

K/C vs System Keyups compares the source's filtered kerchunk count with all keyups observed by the system during the selected timeline. Share of Kerchunks shows what percentage of all filtered kerchunks on the system came from that source. These comparison columns show the percentage on the left and the source's kerchunk count on the right.

K/C vs Others compares a source's filtered kerchunk count with the average filtered kerchunk count of every other active station heard during the selected timeline. Active stations with zero kerchunks remain part of the average. The multiplier is shown on the left and the other-station average on the right.

This filtering affects only the Short Transmissions list and short-keyup leader. Raw transmission events remain preserved in the W7PEN statistics database.

When a filtered kerchunk has an audited statistical attribution in the database, kerchunk-only statistics use the attributed node while ordinary keyups, airtime, and historical activity remain assigned to the node W7PEN actually observed.

W7PEN RF Repeater represents node 654720. Other sources are directly connected AllStar nodes.

Easy-peasy view: Audio Level is a 1–10 incoming-level score with 8 as the target; 7–8 is green, lower numbers mean quieter, and 9–10 mean increasingly hot. Audio Quality is a 1–10 clipping/saturation score where 10 is best. It uses codec-ceiling occupancy and longest flat-top as warning signals; it does not grade noise, EQ, intelligibility, or microphone quality. The technical measurements remain beside the simple scores for anyone who wants them.

Experimental feature — The public audio statistics use each source's five most recent qualifying transmissions within the selected timeline; older measurements remain stored in the database. These five transmissions form a rolling average: each new qualifying transmission enters the display and the oldest of the five rolls off. If you change your audio settings and want the displayed levels to represent the new settings accurately, make five new transmissions so all five displayed measurements come from the new setup. This recent-five display is for live checking only; the nightly audio awards use all qualifying audio measurements from the full award period, not just the five currently shown. Red-row warning: a red station row means at least one of those recent transmissions reached the decoded codec ceiling. Brightest red = the latest transmission reached the ceiling; each clean transmission fades the row one shade until the warning disappears after five clean qualifying transmissions. This lets the display naturally follow a station after it changes its audio settings. Typical Audio is the average of those transmissions' median active-audio levels (P50); High Audio is the average P95 level. Peak is the highest peak among those recent measurements. Ceiling % and Longest Flat-top use the same recent-five window. Values are shown in dBFS, where values closer to 0 dBFS indicate greater digital amplitude. Temporary receive-audio files are analyzed after each transmission and deleted; this page displays only numerical measurements.
