Amateur Radio

Amateur radio has been fascinating me since I was a kid, and I became a licensed amateur shortly after I left school.

Amateur radio is not just a sophisticated hobby. It is a non-commercial radio service for the purpose of intercommunication, education, and technical research. Although it has got a touch of nostalgia in the era of cellular phones and global satellite communication, amateur radio is anything but outdated. In fact, it has been an experimental medium from the very beginning, and many inventions in the field of wireless communication have been (and are being) made by radio amateurs. Moreover, amateurs can provide an alternative communication network in case of natural disasters and other emergency situations because they do not depend on a complicated infrastructure. There are many examples of rescue operations in which radio amateurs have been involved. Actually, one of the thrills of amateur radio is self-sufficiency. A battery-powered shortwave transceiver and a simple wire antenna is basically all you need to communicate with other amateurs, even over thousands of miles.

Running an amateur radio station requires a license issued by your national telecommunication authorities. To obtain one, you have to prove adequate knowledge of radio technology, communication rules, regulations, etc. Further, proficiency in Morse code may be required, depending on the respective license class. The license you get after passing the exam includes a call sign. The latter is your ID when you are "on the air".

As a licensed amateur, you are privileged to build your own radio equipment or modify existing products according to your needs. You are free to experiment as long as you observe the regulations concerning transmitting power, frequencies, spurious emissions, safety, etc. Otherwise, amateurs couldn't be so creative. Alternatively, many commercial products designed for amateur radio are available on the market.

Training courses for people interested in joining the world-wide community of radio amateurs are provided by the national amateur radio societies. You can find the address of your national radio club on the web site of the International Amateur Radio Union, IARU.

Here is a short description of my own radio station:

The following pictures show my present equipment (always under construction):

My Radio Station

Elecraft K2 Transceiver, SWR Meter, Morse Key, Power Supplies

The K2 is a highly sophisticated, compact transceiver designed for amateur radio. It is supplied as a building-kit.

DEBEG 7201 Communications Receiver, Palstar AT1500CV Antenna Tuner

The DEBEG 7201 (= Siemens E 410) is an all-transistor general-coverage receiver from the mid-seventies.

Siemens E 311 Communications Receiver, Drake T-4XC Transmitter, Drake AC-4 Power Supply

The E 311 is from the mid-sixties and still in excellent condition. It is a masterpiece of tube technology and mechanics. If it were manufactured today, it would be unaffordable. My relationship with this receiver is somewhat sentimental because I spent many night shifts in front of an E 311 during my military service back in 1970/71.

Siemens E 309 Communications Receiver

The E 309 (around 1960) is a heavy piece of equipment (weight: 38 kg / 84 lbs). It is a typical receiver from the pre-SSB era. AM and CW reception is remarkably good.
