Ahoj Honzo, přidělal jsem Ti práci , založit JT na 9 cm na WEBu. ES5PC RIG: My setup: 4.5 m dish, circular pol. 80 W PA, made by combining two Toshiba UM2683A 40 W SSPA-s, homemade preamp, currently about 0.8dB NF, round septum feed with chaparral rings (used an old C-band satellite LNB for rings) Got the echoes from the first key-down of my setup. The echoes were at about 549-559 level. 73 Tonda, OK1DAI
