On Dec. 29, 2016, interesting microwave QSOs were in the air: Mike, OE3MZC was on air as OE16YOTA on the 3cm band from Buchbergwarte (Locator:JN78xe). Gerald, OE1GAQ and Stefan, OE1ABU activated OE1XTU (QRG 10.3681 GHz, 250mW, 16dBi horn antenna) on the roof of the Institute of Telecommunications, see fotos below. Other stations heard by OE1XTU: OE1TGW/1 and OE4WOG/p. Below you see Gerald, OE1GAQ and Stefan, OE1ABU while listening to OE16YOTA in SSB using the Schneeberg as scattering object. Although OE1YOTA was clearly heard, a QSO with OE1YOTA was not accomplished. At least one QSO with Gerhard, OE1TGW/1 was completed. Next time better using directive antennas with significantly larger gain.
