Amateur Radio and Ham-Spirit

I received my Swiss amateur radio license in December 1983 and was active until 1986 mainly on Oscar-10. After a 30 year interruption (QRT) I started again from scratch in March 2016. Equipment at home, remote DX-Station and all QSOs (10'000+) had been made since March 2016.

Hams know there is no other service like ours. No fraternity on earth has the power & magic to bridge culture, nationality, distance and disparate interests like Amateur Radio does.

Amateur radio, also known as ham radio, describes the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication.

The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with an identifying call sign such as HB9RYZ.

NEWS 2021

On June 17, 2021 we installed the new OptiBeam OBDYA12-5. A 12 Element Driven Yagi Array 20/17/15/12/10m. This is the first OptiBeam of this type installed in Switzerland. At the same time we installed a Wellbrook ALA1530LN Loop for the new WebSDR Server (HF) with a new Diamond X-50N (2m/70cm) Antenna for the new WebSDR Server (UHV/VHF). We also installed a FlightRadar Station for the Buochs airport where is also the homebase of Pilatus Aircraft.

On June 11, 2021, we installed a new high-end cabinet built to our requirements for all our equipment. Now we have significantly more space for new projects and thanks to the side door a better maintenance access.

NEWS 2020

On June 26th we were finally able to successfully put our new Remote DX station back into operation after the winter storm. At the top is the OptiBeam OB5-6 (6m) and below is the LZA 10-5 10 element Beam (10-20m). Underneath is our HyEndFed8 for 30-80m. More details here

OmniRig v2.1 is now called "MultiRig v1.0". We will soon publish the source code of "MultiRig v1.0" on Git-Hub. Every HAM software developer is welcome to implement our new MultiRig solution. Please contact us at

Winter Storms in February 2020 - Rebuild in June 2020

Three strong winter storms (Petra, Sabine and Bianca) totally destroy all our antennas.

Our remote station had already survived several severe thunderstorms (including one that un-rootet a large fir tree close by), so we thought we were safe. The trouble started with storm Petra. There was already ice on the antennas and storm Petra came with heavy snow and strong winds. It broke off two elements of the the 6m beam and bent the top tube. The 40m EndFed wire was torn apart. The pictures below show the state after storm Petra.

The next storm (Sabine) was even stronger than Petra, but it did not do additional damage because there was little snow on the antenna at that time. Snow and ice have an incredible effect on the wind load. The following picture shows the antenna after storm Sabine. The HF beam recovered nicely once the snow and ice was gone and was still working OK.

The last storm Bianca did the rest. There was again a lot of snow and ice on the antenna. The top tube broke apart and everything came down (see the picture below from the morning after).

Due to the current world-wide Corona health crisis we cannot replace the antennas immediately. However, we have already fixed the EndFed antenna and the KiwiSDR is back online for you. We have replaced the FlexRadio 6500 with a FlexRadio 6700 and added two AirspyHF+ SDR's that are able to monitor the bands 24/7 using WSPR and FT8.

Installation 29. August 2019

Almost 2 years ago we carried out first talks with representatives from Rigi Railways Inc. about the possibility of renting a no longer used mast 1660 metres above sea level and using it for Amateur Radio. In autumn of 2018 we installed a temporary G5RV and two Colibri SDR receivers to find out if this location could be used for amateur radio. We found that we had some noise up there, but it was A LOT better than what we encounter at the home QTH of HB9RYZ and HB9CQK! Planning went ahead and Frédéric HB9CQK and myself decided to get our HAM Dream finalized.
