F8KCF Radio Club is sometime active on 432MHz via EME, CW & JT modes.
EME is often refered to as “Moon Bounce”.
EME stands for Earth-Moon-Earth transmissions and it is literally bouncing signals off the moon and back to earth.
Ham Radio operators can communicate with these weak signals.
Big antennas & large dishes can collect these signals and make them much clearer than can be received with smaller ones.

Our antenna for 432 is a 4×37 elts , 13 lambda, design DJ9BV, home made by Claude F1BHO.
Special thanks to André F4DIA, our Aluminium sponsor !
We are also working on a big dish , about 3.80m, for 1296 MHz.
Preamplifier design DJ9BV with MGF1302 , 0.4dB NF built & provided by Jean Paul F5AYE.

Power amplifier is in another room to avoid fan & airflow background noise.

Claude, owner of the station, almost built all equipments from second hand hardware, including the AC power generator !

Antenna support, rotors & tracking come from a weather radar system. Thanks to Phil F5JWF for his help!
The mast, motors/actuators and tracking controllers have been fully rebuilt and adapted for EME by F1BHO and F5DJL for digital parts.
A PIC microcontroller is managing interface between EME software and tracking devices.

Our EME station is installed on the top of the Salève, a little mountain ,very close to Geneva and the Swiss border, in JN36CD.
The site is very quiet, far from electrical noise. We are 1284 m above sea level.
Unfortunately, we have no electricity and no DSL line.
Our partner, the swiss club IAPC provides hi bandwidth Internet via HAM-Net over a wireless 5Ghz link managed by Marie Pierre F5DN.

Claude installed an home made power generator built with a used car engine and a big alternator.
The engine is powered by a mixture of diesel fuel oil and french fry oil. It smells like Mc Do**ld ..

Power Amplifier is a refurbished Thomson-Plisch TV transmitter, modified for 432MHz.
The power is not communicated by Claude, the chief engineer form « F1BHO Heavy Industries Inc. » .
He said « It’s like a Rolls Royce, there is enough power, simple as that. »
After investigations, we think we probably have more than 1KW , the TH313 tube is loafing !

We are active in CW and JT with multiple computers & dedicated software.
The transceivers are IC910, TS850 or TS2000 with a 432/28 transverter, and an SDR receiver.
