EQUIPMENT ON 24 GHz EME
• 2.4 m Solid dish (Andrews)
• 11.5 W Kuhne SSPA (10 W at feed) short WR42 flexible W/G to W/G Switch (~0.5dB loss)
• Feed: Super VE4MA choke flange with Circular to rectangular transition (WR42)
• W/G switch: “EVENTS HORIZON”
• LNA @ feedKuhne 1.5dB NF 27 db gain + DB6NT design (homebrew) NF= Max 2.0dB Gain = 11.5dBTotal gain is 38.5dB in “feed box”
• LMR240 with Radiall 18GHz connectors for short run on Tx and Rx from “feed box” to transverter
• Transverter = Thales 26 GHz units running 1296 MHz IF. Then 2nd down-conversion to 144MHz IF.
• Kuhne 24 GHz W/G filters on Rx and Tx ports of Thales unit. (Absolutely necessary due to very poor image rejection ~4dB only with 1296 MHz IF)
Perfomance:
• Best Moon noise measured at 2.2dB
At low path loss and low levels of libration my echoes are audible.
