Logging and confirming contacts: LoTW, eQSL and paper cards

A contact nobody confirmed still happened. It just does not count toward anything.

The short answer

Log date and time in UTC, band, mode, callsign and both signal reports for every contact. Confirmation happens through Logbook of The World for most awards, through eQSL for its own program, and through paper cards for the ones people actually keep. Electronic confirmation is free after a one-time identity verification and matches automatically.

A log is not a legal requirement for an amateur station in the United States, which surprises people. You keep one anyway, for three reasons: it is the only way to claim any award, it is the record you reach for when somebody asks whether you worked a station, and it turns out to be the most interesting document in the shack after a few years.

The mechanics are simple and the conventions are worth learning correctly the first time, because a log with local times and inconsistent band notation is a log you cannot use later.

This page covers the fields, the time convention, the file format everything speaks, and the three confirmation systems.

What to record

Log fields

The six fields every contact needs, plus the ones worth adding

FieldExampleWhy

Time0247UTC, 24 hour, no colon
CallsignW1XYZExactly as sent, including portable suffixes
Band20mBand rather than exact frequency for award matching
ModeSSBSSB, CW, FT8 and so on
Report sent59What you gave them

GridFN42Needed for VHF and for grid-based awards

Award matching compares callsign, band, mode, date and time. If any of those disagree between the two logs by more than a small window, the confirmation fails, which is why sloppy time entry is the usual cause of a missing confirmation.

UTC, and why local time ruins a log

Every amateur log runs on Coordinated Universal Time. It removes time zones, it removes daylight saving, and it means two operators on opposite sides of the world write the same timestamp for the same contact. That last point is the entire reason: confirmation systems match logs against each other, and they cannot do that if one side logged local time.

  • UTC does not observe daylight saving. Your offset from it changes twice a year even though UTC does not.
  • Evening contacts in the Americas fall on the next UTC date. A contact at 8pm Mountain time in summer is 0200 UTC the following day, and logging it under yesterday is the single most common logging error.
  • Set your logging software clock source to UTC and never convert by hand.
  • Write the date in year, month, day order in your own notes. It sorts correctly and it removes the ambiguity between day-first and month-first conventions when you work stations abroad.

ADIF, the format everything speaks

ADIF is a plain text interchange format that every logging program, every confirmation service and every contest robot reads and writes. It looks unpleasant and it never matters, because you never edit it by hand. What matters is that your log can export it, because that is how a log moves between programs and how it reaches an award system.

The practical rule: whatever you use, export an ADIF file periodically and keep it somewhere that is backed up. Logging software comes and goes. ADIF has outlived several generations of it.

The three confirmation systems

Logbook of The World
The system nearly every serious award uses. You verify your identity once, receive a digital certificate, and then upload signed logs. When another station uploads a matching entry, the contact is confirmed automatically. Free to use, with a fee only when you actually apply for an award. This is the one to set up first.
eQSL
A separate electronic system that produces a visual card and supports its own award program. Easier to join because there is no identity verification, which is exactly why the major award programs do not accept it. Worth having as a second channel, not as your primary one.
Paper QSL cards
A printed card sent by post, directly or through a bureau. Slow, and the only confirmation anybody pins to a wall. Direct exchange with return postage takes weeks. Bureau exchange costs almost nothing and takes a year or more. Many operators send cards only for contacts that meant something.

Choosing logging software

There is no single right answer, and the choice matters less than committing to one. All of them export ADIF, so switching later costs an export and an import.

  • A dedicated desktop logger is the traditional choice, works offline, and integrates with rig control so band and mode fill themselves in.
  • A cloud logger syncs across devices and handles confirmation uploads automatically, at the cost of needing a connection.
  • WSJT-X logs digital contacts itself and hands them off to whichever logger you point it at, so a digital-heavy station needs almost no manual entry.
  • Paper works, and plenty of portable operators use a notebook and type it up later. A Camp Field folding aluminum table and a pencil in a field kit is a perfectly respectable logging system.
  • For an award chase, pick a logger that tracks worked and confirmed status per entity, band and mode, because doing that by hand becomes impossible quickly.

Every one of these depends on the other station confirming, which is why the confirmation system matters as much as the log. See how to work POTA for the one on this list you can complete this weekend.

What removes the manual entry

Rig control fills in band and mode automatically, which is where most logging errors come from.

Common questions

Questions people ask about this

Am I legally required to keep a log?

Not in the United States. The FCC dropped the logging requirement for amateur stations years ago, so there is no rule about what you must record or how long you keep it. You keep a log because every award requires one, because it settles questions about whether a contact happened, and because it becomes a genuinely interesting personal record after a few years.

Why did my contact not confirm on Logbook of The World?

Nearly always a mismatch between the two logs. The system compares callsign, band, mode, date and time within a tolerance window, so a contact logged in local time instead of UTC, a date off by one because the contact fell after midnight UTC, or a band typed as 20 when the contact was on 17 will all fail to match. Fix your entry and re-upload.

Do I have to send paper QSL cards?

No, and most operators now confirm almost everything electronically. Cards remain the tradition and the thing people display, so many operators send them only for contacts that mattered: a first contact, a rare entity, a friend. If somebody sends you a card with return postage, sending one back is the expected courtesy.

What is the difference between LoTW and eQSL?

Logbook of The World verifies your identity before issuing a signing certificate, which is why the major award programs accept it as proof. eQSL has no identity verification, joins in minutes, and produces an attractive electronic card, but the same lack of verification means most award programs do not credit it. Use both if you like, and treat LoTW as the one that counts.

How far back can I upload old contacts?

Indefinitely, as long as your log has accurate data. Logbook of The World will accept logs going back decades provided you hold a certificate covering the callsign and the date range in question. Many operators upload a lifetime of paper logs after they set the system up, and confirmations arrive for contacts made years earlier as other operators do the same.
