At this moment I am planning a new system based on modules from Kuhne Electronics and a waveguide switch from OE2JOM At the end of January 2017 all modules have arrived and I have started building my new system It should be giving about 0,8 Watt output and an overall noise figure below 6 dB When it is ready it will look a bit like the system from OE2JOM
This project is my first project in microwave building the new way.
In the old days I always build my modules myself, sometimes
using ready PCB's and prepared housings but always assembling the microwave
module myself with soldering all components and tuning the module for optimal
performance. I started by individual checking of the different modules First I checked the LO and the transverter.
I started preparing of the housing of the new system I needed to build in a ground plate to hold the different modules
At this time I was also experimenting with a Raspberry Pi 2 using a small 5 inch display. When this was working I came up with the idea if I could build a Pi with an SDR radio for displaying the spectrum on 47 GHz to be able to see signals which are not audible yet. After searching the internet I found a SDR program which should work on the Pi called CuteSDR. At first I installed this on my windows computer which worked fine connecting to internet webSDR radios. I started with installing CuteSDR program on the Pi which
succeeded but then I did not succeed in getting it to work with a funcube dongle
pro plus.
