1961: Born in Luzern, Switzerland; 1967-1973: Primary school; 1973-1981: Secondary scool; 1981-1988: Studies of mechanical engineering and computer science with final degree Master of Science ETH in computer science; First license (CEPT class 2, radiotelephony above 30 MHz): 1989; Second license (CEPT class 1, radiotelegraphy, all bands): 1990; Other hobbies: General aviation (private pilot lincenses for aeroplane and helicopter), motorbike riding.

Activities on air: 99% Digimodes (APRS, PSK, Olivia, JT65, JT9, WSPR, QRSS, Slow-Hell, Pactor, AFSK Packet and Robust Packet) and 1% SSB with a 100% solar powered station, whenever possible without the "help" of the Internet (no EchoLink, no DV call routing, no APRS iGating), usually transmitting at low power levels (around 10 Watts or lower). Mainly using Elecraft transceivers (KX1, K2, KX2, KX3, K3) on HF and Motorola/Hytera transceivers on VHF/UHF. Antennas @ hombase station: outdoor inverted Vs for 80/40/30/20m, indoor inverted Vs for 17/15/12/10m, all monoband.

Pactor: station (SCS PTC-IIex & Dragon DR-7400) is QRV occasionally for message receiption/transmission via Airmail/RMS Express P2P mode on 14109 kHz (center frequency).
