The DL5NO Amateur Radio Homepage

Welcome to my shack!
DL5NO in his shack

Amateur radio (also called “Ham Radio”) is a friendly high-tech hobby that has got something fun for everyone. Radio amateurs use radio stations (transmitters and receivers) from their homes and outdoors to get in contact with other amateurs around the world, even complete strangers. They communicate with each other using morse code, voice or computer-supported digital modes. About 3 million people troughout the world enjoy this interesting hobby. In all countries amateur radio operators have to pass an examination to demonstrate technical knowledge, operating competence and awareness of legal and regulatory requirements. More about amateur radio at Wikipedia….

The callsign “DL5NO” has been assigned to me after I have passed the amateur radio exam in 1975. Some time afterwards I received a diploma in electrical engineering from the University of Erlangen. I worked in medium-sized and large ICT companies in various positions from development engineer to CTO and technology consulting manager. After retiring, I now find more time for my hobbies, which besides amateur radio include skiing and playing piano.

Amateur radio offers many different possibilities to become active: Radio amateurs may build transmitters, receivers and auxiliary devices for their own use without a certification of the equipment and operate the equipment in internationally allocated bands of the radio spectrum. Within this framework most radio amateurs have their special preferences. My main interests in this hobby are:

  • CW (using morse code)
  • DX (far distance connections) on shortwave
  • Contesting
  • Digital modes (RTTY, PSK31, FT8/FT4, JS8)

As a trainer I also support preparatory courses for the amateur radio exam.

Within my webpages, I’d like to give some impressions of my activities as radio amateur. Just click through my website…

There is also a DL5NO social media space at Mastodon (posts are in German).
