You may have worked 4U1ITU recently or you may have seen some 4U1ITU cluster spots. The operation is real and the station will be on the air until 3 June. After a two year lock down, the ITU building in Geneva is back in business. Currently a series of meetings of Study Group 4 (satellites) and 5 (terrestrial and amateur) Working Parties takes place.

The two year lockdown has not been good for equipment and antennas. Lots of technical issues had/have to be solved. As it looks now (but we have to wait and see) 4U1ITU can operate on WARC bands with dipole fixed NW/SE and use the STEPP-IR on 40/20/15/10. A second radio is now being set up for 6 meters including FT8.

This activity will most likely be the last one before the reconstruction of the ITU building starting by the end of the year. The shack will be closed soon for several years. It is recommended to fill empty bandslots now.
