I started with Amateur radio in 1965 with a Hallicrafter shortwave receiver and crystal controlled CW transmitter. After some years on shortwave I become interested in operating on 2 m. I built a receive konverter from a kit and a crystal controlled transmitter with QQE03/12 as final amplifier.

This started my interest for the higher frequency bands. At that time, building your own equipment was the only way to become qrv on VHF/UHG. In 1985 I built my first 10 GHz transverter with waveguide parts. The raising satellite TV industri made low noise FET trasistors available and now I designed a new transverter with FETs  on a modular
with 3 FETs in the RX and 3 FETs in the TX with the impressive output power of 200mW into a 90 cm dish.

In 1987 a moved to my present QTH in the country side. I raised a 27 m rotatable tower. The new QTH was not perfect for stationary microwave operation. A closeby hill 60 m higher than at my QTH made operation i direction west almost impossible.
After a period of almost 12 years I was QRT. The
