What's EME System ?

Track the moon or any selected radio source with :

• A high accurate (16 bits) Azimuth/Elevation display (runs also without the interface)
• A complete real time dialogue with the hardware interface to point your antenna toward the moon or the selected source with the same accuracy

Manage the traffic procedures in real time with :

• The DXCC Common window world map including the moon footprint, the spatial polarization offset, a complete DXCC database
• The traffic management including the Doppler shift calculation, the RX/Tx corrected frequencies and RIG dialogue, the elapsed time during the Rx/Tx sequence, a text grid to memorize your traffic information (Date, time, freq, call sign, report…) or skeds
• The brightness sky map with the sky temperature at the working frequency, the location of the different radio source (hot and cold), the antenna beam to the sky, your own radio electrical horizon and some astronomical information about the moon (range, hour angle, declination…)

Calibrate the station with :

• The measurements of received levels
• The 2 axes antenna diagram measurement with an automatic scanning
• The tracking of radio-sources
• The complete calculations for an EME budget or noise measurement
• The 2 axes angular corrections

Plan the EME activity to prepare your skeds or traffic period.

• A new front-end module (launcher) to manage EME System and launch directly the other modules
• An initialization module (emesetup) to set the parameters ( callsign, location, serial port, end-stops, station parameters, frequency...) called by the control module.
• A control module (tracking) capable of handling an EME station in real time ( Automatic tracking of sources, traffic periods, Doppler and RIG dialog, polarization, signal level, common window, sky noise temperature, Rx/Tx management ...).
• A module (planner) to plan the EME activity (Moon location, Common window, Doppler, sky temperature ....) or analyse the EME months data.
• A module to edit the prefix and countries DXCC database (dxccedit).
• A module to create an angular correction file of the antenna system (included to emesetup).
• A module to help the operator about EME calculation to evaluate the average performance of the EME station (emecalc)
• A new hardware interface between the control software and the EME station (Motors, angles monitoring, receiver...).

• It needs a free RS232 com port to connect the interface.
• This version runs on a PC compatible with Microsoft Windows (95 and up) and VGA or SVGA monitor.
• The new interface is 100% compatible with the current one.
  • It uses numerical inputs (TTL compatible : 16 bits for Az & El).
• It includes 4 relays ( 2A max ) to drive azimuth and elevation motors (Up, Down, CW, CCW).
• Moreover it adds
  • a new RS 485 interface to support USD & MAB encoders,
  • a new analog input to allow an easy antenna diagram measurement
  • a new analog output to implement speed control option.
• The interface needs a single 12V supply (or 5V without regulator).
• The new PCB (double sided, plated through holes and silk screen) is available.
