On this page are only a few of the many projects I have been involved over time.

Next Generation Beacons hardware

I have designed a lot of the Next Generation Beacons hardware used for OZ7IGY and a dozen of other beacons world wide.

Station controller

I designed this station controller to control all my  VHF to SHF transverters, low noise amplifier modules, PA and antenna switching including relay delay control etc.

Relay and splitter board

This small antenna switch was designed as a part of the station controller and for RF switching in the antenna mast system.

FET PA input controller

I designed these input controllers to secure no overdrive to the expensive 1.25 kW MOSFET pa units, they also include RX shift, bandpass filters and a Wilkinson power splitter to feed two 1.25 kW PA units.

DanAmps PA

I designed these HF power amplifiers as a part of DanAmps business but they were too expensive to build in Denmark so only 10 prototypes were made.
