AUSTRALIAN REGION IONOSPHERIC SUMMARY MUFs at Sydney were 30-60% enhanced until 06UT, 15-30% enhanced 07-18UT, and near predicted monthly values thereafter. T index: 72 4B. AUSTRALIAN REGION IONOSPHERIC FORECAST DATE T-index MUFs 16 Feb 30 Near predicted monthly values. 17 Feb 30 Near predicted monthly values. 18 Feb 30 Near predicted monthly values. Predicted Monthly T Index for February is 30. 4C. AUSTRALIAN REGION COMMENT Regular Sporadic E layer, and continued geomagnetic activity, may have combined to degrade local propagation conditions yesterday. Similar conditions are expected for today. Conditions at Townsville appeared normal yesterday. -- Dave Horsfall (VK2KFU) VK2KFU @ VK2OP.NSW.AUS.OC PGP 2.3 dave@esi.COM.AU ...munnari!esi.COM.AU!dave available ------------------------------ Date: Mon, 14 Feb 1994 10:54:32 GMT From: ucsnews!sol.ctr.columbia.edu!howland.reston.ans.net!pipex!bbc!ant!boyer@network.ucsd.edu Subject: Landsat Transmissions To: ham-space@ucsd.edu I have seen the orbital elements for Landsat in this group. Does anyone know about the transmissions from this sat. Yes we have all seen the great pickies, but is it at all feasable for 'joe public' to receive and decode the info? Has anyone got frequecies and info on the modulation?

To: ham-space@ucsd.edu Has anyone tried to make a contact by bouncing a signal off the ionized gasses surrounding the Shuttle as it re-enters? I assume it would work just like meteor-scatter, except it would be predictable. When there is a high-inclination orbit (like 57 degrees), a KSC landing puts the re-entry path over the middle of the US. Anyone want to try a VHF QSO? -Bill VanRemmen billy@urhep.pas.rochester.edu URHEP::billy My opinions. No one else's. Definitely not the U of R's. ============================================================================== "Experience should teach us to be most on our guard to protect liberty when the government's purposes are beneficient . . . the greatest dangers to liberty lurk in insidious encroachment by men of zeal, well meaning but without understanding."
