In the occasion of the World Radio Day and the International Marconi Day the G.R.I. ALFA TANGO, for the first time ever, will be on the air with some special event stations.

For the year 2021 there will be three different special event stations:


1AT/WRD - World Radio Day celebration: 13/14 February 2021

1AT/IMD - International Marconi Day celebration: 24/25 April 2021

1AT0 - Exactly after 30 years the 1AT0 is back! It will be active in both sessions, thogether with WRD and IMD.

This is not a contest.  There are no rankings or special prizes.The special stations (1AT/WRD - 1AT/IMD - 1AT0) will operate as simple S.E.S. and will answer to all the hunters worldwide in honor of the Radio and in memory of its inventor Guglielmo Marconi.


The event is open to all 11m operators and prior registration is not required.
The special event will take place in two sessions:

  1. The first session starts at 00:00 UTC on Saturday 13 February 2021 and ends at 23:59 UTC on Sunday 14 February 2021 (48 hours)
  2. The second session starts at 00:00 UTC on Saturday 24 April 2021 and ends at 23:59 UTC on Sunday 25 April 2021 (48 hours)

Band and bandplan:
Activity must take place on 11m band. The section of the band between .500 and .600 included (called DX part) cannot be used for QSO. In fact, our special stations will operate on the basis of this bandplan.
Participants are encouraged to comply with current legislation regarding the use of their equipment and the allocated band.
Hunters can only make QSO with special Event stations once. The two sessions are considered as a single "on air" event period. DUPE QSO are not allowed.
A hunter, at most, will make three different QSO.
Exchange and Validity of contacts:
There is no serial number system (no progressive numbers).
Just 59 or 599, in the log.
The validity of the QSO will be verified by our softwares. There is no need for hunters to submit their log: QSO will be confirmed based on the special event stations logs.
QSL system and Certificate download:
There is no paper QSL.  All QSO will be verified and confirmed through and that QSO confirmation will be full valid, for all purposes.
On the end of the event all hunters will be able to download their participation certificate (full color award A4) from the AT Portal.
