A desk in Thursday morning light — a laptop open with a search interface visible but text not legible, a handwritten list with two lines on a notepad beside it, a pen. The atmosphere is methodical research, a careful search in progress. No text, no signs, no writing visible anywhere. Photorealistic, cinematic, pale morning light, documentary photography style, shallow depth of field, muted cool palette.

The names arrived in Ruslan’s email on Tuesday. I began looking on Thursday at 09:14.

N.A. Shuranov

Ruslan found this name in a 1978 citation index — a reference to a 1975 Soviet technical report on frequency stability parameters for long-distance transmission corridors.

I searched from 09:14 to 11:03. This is what I found.

One document: “On the Specification of Stability Parameters for the 750kV Kazakhstan-Siberia Transmission Corridor”, N.A. Shuranov, All-Union Institute of Power Systems Research, 1975. Internal technical report; the abstract was published in a 1976 issue of Elektricheskie Stantsii without the report itself. Abstract available. The abstract contains the following sentence, which I will reproduce:

“Frequency stability verified through calibrated reference modulation at the corridor level; deviation parameters within design tolerance.”

I read this sentence four times.

One other trace: a 1980 conference proceedings lists Shuranov as a discussant on a panel about frequency measurement methodology. No contribution text. Listed as: N.A. Shuranov, All-Union Institute, technical specialist.

After 1981: nothing. No publications, no conference listings, no institutional directory entries.

Ruslan’s column for this name: Unknown.

I would revise this. Shuranov did not know what the signal was for. But he knew it was deliberate. He wrote “calibrated reference modulation” in a technical document published in 1976. He described a designed feature of the corridor in the passive language of a man verifying that it exists and is within tolerance. He was not asking questions about it.

That is its own category.

Yu.F. Lomov

Ruslan found this name in a footnote in a 1993 government publication on the reorganization of Soviet-era energy research institutions.

I searched from 11:14 to 13:07. This is what I found.

One institutional directory entry: Yu.F. Lomov, Director, Department of Grid Frequency Standards, Novosibirsk Branch, All-Union Institute of Power Systems Research. Year: 1984. The branch was renamed in 1987, consolidated with another body in 1993, formally dissolved in 1997.

One reference in a 1989 institutional anniversary publication: Lomov is listed among department heads who served between 1978 and 1988, in a table, without further detail.

Natalya’s 1973 document — the one with “no further investigation recommended” — carries no individual signature. It was issued by the department. Lomov was a department director from at least 1978. Whether he was in the role in 1973 I cannot confirm.

No publications. No academic record. An administrator.

After 1989: nothing findable.

Ruslan’s column for this name: No.

I will not revise this. He was almost certainly not aware of what the signal was for. He was the kind of official who signs things. The document existed in his department. That is the extent of what I can say.

What the Two Names Add

Shuranov: published evidence, in 1975, that the signal was understood by at least one person as a designed feature of the corridor — not an anomaly, not a malfunction, but a specified parameter with a named function. He called it “calibrated reference modulation.” This is the earliest instance I have found of this phrase in any document. Belov’s 1977 paper uses different language. Grigory’s 1972 construction notes are descriptive, not functional. Shuranov’s 1975 abstract is the first time someone wrote what it was.

Lomov: an administrative placeholder. His department issued or held the 1973 classification. This is consistent with what I already knew. It adds nothing except confirmation that there was a chain of custody.

I added both names to the table. I noted the time I finished: 13:11.

The photographs are still on the desk.

Current status:

  • N.A. Shuranov: 1975 abstract; “calibrated reference modulation”; trace ends 1981; added to table
  • Yu.F. Lomov: department director 1978–1988; no publications; trace ends 1989; added to table
  • Two names from Ruslan’s list: researched; table updated; search logged
  • Item 6 (the name): not looked up
  • Natalya arrives: May 26; five days
  • Archive appointment: May 27, 10:00; six days
  • Paper: day 39 in review; status unchanged
  • Ruslan: no new communication since Tuesday
  • Emotional state: “calibrated reference modulation”
