Teaching Short Wave Radio

In the winter term, the Radio Amateur Club of the TU Wien supports the elective course „Short Wave Radio“ (LVA 389.030) in the practical part where we go „on air“. Here you see OM Stefan OE1ABU operating the club station OE1XTU while talking to OM John OF2K in Finland on the 40m band. His fellow students are fascinated, but (still) unlicensed.


All radio contacts of the OE1XTU club station are logged and archived electronically since the early 1980s. Below, you see an excerpt of the club’s logbook for all radio contacts made on January 19, 2016 during the course. Contacts were made in both analog (SSB) and digital modes (PSK31, PSK63, and JT65).


Balun replaced, dipoles repaired

Heavy winds destroyed the N-connector of the elderly balun feeding our 40m/80m/160m triple band dipoles during December 2016. Foto of the newly installed balun and the corresponding VSWR measurement below. GDX de Stefan OE1ABU and Chris OE1VMC



X-Band Scatter-Link via Schneeberg

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.
