Special Call OE40XTU

During 2023, we activate the special call OE40XTU to celebrate the 40th anniversary of the Radio Amateur Club of the TU Wien („Radio-Amateur-Klub der Technischen Universität Wien“). The special call has been globally announced in the ITU Operational Bulletin No. 1257 (1 Dec. 2022), on page 13.

All logs will be uploaded to LOTW, eQSL (AG), QRZ.com and Clublog. Logs will be uploaded (at least) monthly.

Paper cards: Please request a card at clublog.org. All paper cards will be sent beginning 2024.

We will be active on the waves from the „Top Band“ (160m wavelength) to the X-Band (3cm wavelength) including QSOs via QO-100 Satellite.

CQ WW DX CW 2022

Same procedure as last year … same procedure as every year: The last weekend of November is devoted to CQ WW DX in CW. This year, the OE1XTU station participated in the multi-operator category, all bands, high power, assisted and the team members were Gudrun OE1OMA, Helmut OE1TKW and Chris OE1VMC. We have a total of 393 QSOs in our log. Pics below show some details: the N1MM+ Logger in the shack, the waterfall display of the kiwisdr, our main radio FTDX-5000MP, and a map showing all contacts, the colored markers indicate which band was used for the contact.

OE1XTU Team: Manfred OE4MQW (night shift), Gerald OE1GAQ, Tom OE1TRI. Preparations for the contest were ramped up during September due to a recent boot disk failure in the RTU host PC. Chris OE1VMC and Tom OE3PTC were busy with setting up the RTU host again: re-installing the microHam router and N1MM+ logger and configuring.

Photos below were all taken in Saturday Oct. 29, 2022. The photo of our SteppIR DB-36 Yagi was taken from Karlsplatz near the historic Otto Wagner pavilions.

We participated on Saturday only with 200W of Tx power: Multi-Operator, Single Transmitter, All Bands, a total of 487 QSOs with around 262k claimed score.

OE Headquarter Station 15m SSB

Our station of the Radio-Amateur-Klub of the TU Wien serves as one of the headquarter stations in this year’s IARU HF World Championship. We operate in SSB on the 15m band.

Our rig is based on a FT-5000MP which we hooked up to a historic Collins Radio „30S-1“ Power Amplifier (PA) yielding robust QRO performance. This is a linear PA based on a single tetrode tube suitable for CW and SSB on all HF bands. The PA was provided by Roman OE1RMS in late 2021 and Roman was very helpful in explaining its tuning and operation. Many thanks also to Roland OE1RSA for organising transport of this impressively heavy piece of hardware.

The antenna in use is our SteppIR DB36 Yagi.

The station is operated during the contest weekend (July 9-10, 2022) by Gerald OE1GAQ, Thomas OE1TRI, Dominik OE1ERT, Manfred OE4MQW and Chris OE1VMC.

OE1XTU is QRV on QO-100 Satellite

The Radio-Amateur-Club of the TU Wien has set up a ground station for the Es’hail 2 satellite (QO-100) in geostationary orbit in the course of several student projects. Shengya and Mariam have manufactured the POTY Feed and constructed its positioning relative to the dish. Mariam, Le and Artan have completed the system integration for the ground station. Basic configuration and pictures follow below.

Receiver (X-band downlink, 3cm)

Generally Assembly of the RTU

On May 24, we held this year’s general assembly of the radio-amateur-klub of the TU Wien which operates with the call sign OE1XTU. Apart from the usual agenda items of the general assembly, we also enjoyed the talk given by Roland OE1RSA on packet radio, its historic roots, and various implementations in hardware and software. The newly elected board for the next two years consists of Chris OE1VMC (president), Gerald OE1GAQ (vice-president), and Tom OE3PTC (secretary and cashier). Two photos below show the club members at the beginning of the meeting (right photo, taken at the roof of the institute of telecommunications) and in the roundup after the general assembly (left photo).

All Austrian Emergency Exercise 2022

The OE1XTU Team for AOEE 2022 consists of three OPs: Dieter OE1KDK, Gerald OE1GAQ and Chris OE1VMC. This year, the 40m band opened nicely in the afternoon session. The raw OE1XTU score map (before log checking) from the SaigaAOEC Logger is shown below. Districts coloured in blue have been contacted solely on the 80m band. Districts coloured in green have been contacted solely on 40m. Red districts were contacted on both bands, while white colour indicates districts without contacts.

Girls Day 2022

Friday, April 22, 2022 was declared a „Girls Day“ for amateur radio stations in OE-Country. On that day, unlicensed female individuals could operate amateur radio stations under supervision of a licensed ham. The photo below shows Sophie at our YAESU FT-5K rig. She called CQ on 20m and 15m in SSB and we have several QSOs in the log, including one with W4RN in North Virginia.
