Direct QSL requests

Direct requests received by the QSL Manager receive direct replies when the following requirements are met.

Card size: 3½ × 5½ inches (90 × 140 mm). Up to eight QSOs can be confirmed on a single card.

  • Ensure QSO details are clear and correct. Dates and times must be in UTC.
  • Enclose a good-quality, self-addressed envelope (SAE) large and strong enough for the return cards. Do not use airmail envelopes or send labels alone. If postage is sufficient, the QSL Manager will apply an A-Priority stamp.
  • Enclose US dollars or sufficient valid, properly stamped International Reply Coupons (IRCs) for postage. Loose Swiss postage stamps are also accepted. Stamps and currencies from other countries cannot be used.
  • Do not send other currencies or cheques. Requests without an SAE, with an undersized envelope, or with insufficient postage will be answered through the bureau.
Donations are appreciated and help fund new QSL cards and bureau returns. Every effort is made to provide a reasonable turnaround time. Requests involving multiple callsigns may take longer; the reply is mailed after the final callsign on the request has been processed.

Direct return postage

Number of cards Within Europe Outside Europe
1–3 cards $3 or 1 IRC stamped in Europe $3 or 1 IRC stamped outside Europe
4 or more cards $4 or 2 IRCs stamped in Europe $5 or 2 IRCs stamped outside Europe

The original policy also states “Europe: 3 greenstamps; Overseas: 3 greenstamps” under direct postage from Switzerland. Both statements are retained here pending confirmation of current postage requirements.

QSL via the bureau

Preferred method: Request a bureau card through Club Log OQRS.

Alternatively, send bureau QSL cards to the USKA (Union of Swiss Short Wave Amateurs) bureau via HB9BOU.

Logbook of the World

4U1UN uploads QSOs as quickly as possible. Existing computerized 4U1UN QSOs beginning in 1993 are uploaded to LoTW and Club Log.

Some older paper-log QSOs have also been entered into the computerized log and uploaded.

QSOs for 4U60UN, 4U64UN, 4U70UN, and 4U75UN have been uploaded to LoTW.
