Microwave-Experimental-Radiostation of Peter Cerveny EA6ADW/P (EA6/DF5JJ) in JM19NW, 370m ASL Operating periode 1996-1999.
10368 MHz: SSB/CW 100cm-offset-dish, f/D 0.80, 38dBi, 15dBi-Horn-Feed (long version) TX MGF2340 1.2W out RX NE32584 nf=0.80dB local oscillator OCXO (70°C) frequency-accuracy/stability is better 500Hz on 10368MHz! azimuth-accuracy is better 0.5° with 50cm-scaled-disc (3mm/degree resolution)
24192 MHz: SSB/CW, same 100cm-offset-dish 15dBi-Horn-Feed (long version for low phase error loss) transverter full WG-version TX: 2xMGF1303 parallel, 90mW output RX: 2xNE32584 nf=1.70dB + 0.10dB by WG-switch
Measurements on 24192MHz in 9/1998 (100cm-dish): sun 8.5dB S+N/N (SolarFlux 135), earth=4.0dB with horn, 3.75dB in dish gain=46.3dBi, G/T=23.5dB, Ta=35K, Tcs=5K The transverter heads can be change in 10 sec. without shift in az./el. (error <0.2°)
ODX 10368MHz: 27.th june 1999 9H1ES/P, JM75FV, RST 55/59, 1090km wkd 29 grids total ODX 24192MHz: 10.th may 1998 EA5/F6GBQ/P, IM98XR, RST 419/419, 226km , (at 18°C, 85% humidity!) wkd 7 grids total
On 10368MHz made maritim-mobil-QSO with F6BVA/MM in JN22VT, RST 55/57 over 386km as MM-worldrecord at 08.th july 1997. Later two further MM-QSOs were done.
