[Fourlanders] FW: [VHF] MRO Electra SDR post-launch checkout

[Jim Worsham]

I think this would be a very cool thing to do.  I am sure there are folks on
these reflectors with the gear and antennas to do this.  I assume this would
take a fairly large dish so I copied Ray, WA4NJP and Charles, K4CSO because
they are the only guys I know with access to a dish.  Anyone else interested
in doing this?

Subject: [VHF] MRO Electra SDR post-launch checkout

Advance information, subject to change:

Post-launch checkout of the Electra software-defined UHF radio aboard 
the Mars Reconnaissance Orbiter will be conducted on or about 26 
September 2005.  These tests will include CW transmissions during 
spacecraft turns to verify the UHF quadrifilar helix antenna pattern. 
Interested radio amateurs and amateur and professional 
radio-astronomers in North America with sensitive receiving 
capabilities at 437.1 MHz can attempt to receive the UHF signal from 
MRO during this test.

More details will follow.
