LA0BY is my amateur radio callsign, assigned by the Norwegian Telecommunications Authority. I have also had a national license in Germany with the callsign DF9PY. I am a member of the national amateur radio organizations NRRL (Norway) and DARC (Germany). My favorite subjects in HAM radio are propagation and the construction of receiving and transmitting equipment for higher frequencies. Currently I am also the national beacon manager for Norway and Aurora column editor for the DUBUS magazine.
The amateur radio license gives permission to construct, own and operate radio transmitters, receivers and antennas for experimental purpose on wavelengths from under 3 mm to 160 m. By international agreements (CEPT T/R-61) this permission is extended to include many other countries.
On this site you will find some information on topics related to my Hamradio interests. I try to keep it updated wrt information on my activities.
