Hello, My name is Peter Knol. My interest in the radio hobby started in 1982 when I bought a CB 11 meter rtx. A few Years later around 1997 I got my Novice licence and the radio call PD0SDB. A few years later in 2001 I started learning the theory for CEPT-class-II (thanks Tonny). The results where positive, and I got my PE2SDB call. In 2002 I started Learning CW (thanks Gerrie) and a few months later I got my CEPT-class-I call, PA1SDB.

These day's I'm activer on 10 GHz with a HB100 motion detection device...
Take a look here: http://home.deds.nl/~knol/HB100

At the other end of the spectrum, I'm active on the 630 meter band in OPERA with a Raspberry Pi v3 as transmitter, and a IRF510 based final. The Raspberry generates te 477 KHz signal. The final is keyed in OPERA mode. (OOK)

The IRF510 based final !



Below the variometer coil in a growtent to keep the coil dry !


The antenna is a Zig-Zag. That means 60 meter of wire at 8 m agl. 20m to the far end, then 20m back to the feedpoint, finaly again 20m wire to the far end.
