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

New Antenna back-to-back configuration since June 2015: 100cm mesh dish / 65cm offset dish 

Current station details:

23cm: 100cm mesh dish, triband loop feed

13cm: 100cm mesh dish, triband loop feed

9cm:   100cm mesh dish, triband loop feed

6cm:   65cm offset dish, pyramidal horn, mounted 7deg offset, next to 3cm feed

3cm:   Transverter: NF<1dB, modified DB6NT MK1 with WG-LNA, WG-switch, 45cm Flexguide; PLLXO locked to 10MHz reference,  Antenna: 65cm offset dish, 11m off the ground, homemade dual-mode feed

I use an RTL-SDR USB stick with LINRAD by SM5BSZ.


Inside the 10GHz transverter box

65cm offset dish with 10 GHz and 5.7 Ghz feeds


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.
