SILENT KEY

It is with regret that the SARL is announcing the passing away of Dave Larsen, ZS6DN.

Driving between Pretoria and Johannesburg, many a traveller has been intrigued by a farm of antenna masts on the hill overlooking the main road to the OR Tambo International Airport. Turning off the main road down a narrow farm track one finds the sign "SALBU" the home, the office, the research laboratories of Dave Larsen, ZS6DN, until recently South Africa's living legend of radio. His key has now become silent on 26 February 2014 at the age of 81.

During his life time he worked in the interest of Radio and Amateur Radio technology development. He installed and maintained a 5 five band HF beacon as part of an international Amateur Radio propagation research programme. The multi-band HF beacon is operational from Salbu, replacing the 14100 kHz beacon of which Dave has been the custodian since the inception of the programme many years ago. The beacon operates on 14100, 18110, 21150, 24930 and 28200 kHz.

During the seventies Dave and his team evolved an HF frequency hopping system. The concept was initially rejected by the experts at the time. Some 15 years later the authorative publication, Janes Defence weekly wrote in the 11 July 1987 edition : "Frequency hopping is probably the most popular spread spectrum technique. Claimed to have been pioneered in South Africa, it now appears in tactical equipment manufactured by most of the major international radio communication companies."

In 1989 Dave Larsen, ZS5DN was awarded the Order of the Star of South Africa Grand Officer in recognition of his contribution to electronics.

Today's Amateur Radio Today programme will take an in-depth look at the contribution Dave Larsen has made to the development of radio and amateur radio including historical audio featuring Dave talking about the development of SSB in South Africa. It is on the air a 10 am.

To his wife, family and friend's we offer our sincere condolences.
