(A Project of the Jupiter Space Station)

Equipment Specs and Configuration

A software and hardware vehicle know as the Jupiter Space Station (JSS) is the principal facility for conducting this project and it is fully computerized. The home page for the project and the news group focal point will be The JSS has a fully steerable 12' dish and is presently adding a 24' dish. The JSS system was originally set up with receiving gear (ICOM R71A) to monitor Jupiter at the decametric frequencies. The station was converted to a 1296 MHz higher power moonbounce system which had one simple requirement: hearing its own voice transmissions bounced off the moon, and thereby setting up on weak signal analysis using DSP. The web site details three papers/experiments for pulling out signal 30 dB in the noise and shows some of our late '90s EME results.

C software for the rf capture of a spectrum analyzer, astronomical and solar tracking of the dish antenna (Alt/Az or Equatorial), and JavaScript triggering was developed and will be provided by the JSS (much currently exists in both JAVA and C).

Basically there would be two types of receiving systems. One system at 2380 MHz would receive signal products from 2000 - 2500 MHz [wide bandwidth obviously] by either employing a sweep spectrum analyzer or scanner; sweeping or scanning the downconverted signal [to your ideal IF] or the base frequency directly. An HP 141T with the 8555b plug-in can sweep up to 18 GHz, and we can provide the sweep software for no cost, DigiSpectrum, which can capture sweeps off the video display and save them for "movie replays" later. A sample of a solar monitoring system and the DigiSpectrum data capture can be found at the Jupiter Space Station. DigiSpectrum can also be used to sweep 0 - 500 MHz for solar radio as seen at:


A second setup can be a basic solar monitor looking at signal from 0 - 500 [the standard Type IV signals from a solar flare] which could have the modulation [pulse] embedded in the signal.
One would have to sweep, locate the emission, and then lock on record the signal in a narrower bandwidth [up to 100 KHz] to see and capture this modulation. SpectraPro 3.14 or better could be used for capturing and isolating this returned solar signal.

For the successful candidate to be a Downlink Station, the station should have an ideal minimum equipment configuration (or equivalent) as follows:
