I am mainly interested in frequencies above 1GHz and in the microwave technology involved. Much of the equipment in use is homemade or modified commercial stuff.

Current station details:

23cm: 150W to 17 dB(d) yagi, 3m boom

3cm:   Transverter: NF<1dB, 18W at feed, modified DB6NT MK1 with WG-LNA, WG-switch, 45cm Flexguide; PLLXO locked to 10MHz reference, 144MHz IF
            RTL-SDR with LINRAD by SM5BSZ. Antenna: 65cm offset dish, 11m off the ground, homemade dual-mode feed


Inside the 10GHz transverter box

My QTH is located at the western rim of the river Rhein valley, with a relatively clear take-off to the North and South and some obstructions towards the West and East. The map below shows the radio horizon for scatterpoints at 10kms and 14kms height respectively. These figures represent estimated cloud heights for typical or very intense thunderstroms, observed during the rainscatter season in the summer every year. The maximum achievable rainscatter coverage in an ideal situation is, in theory, twice the distance from my QTH to the virtual horizon line.
