Topband: lower ionosphere?

That is a myth in the making due to poorly written press releases. If 
you dig into the details, you'll find that the satellite was only 
measuring the equatorial ionosphere (the orbit inclination is 13 
degrees) at altitudes from about 400 km to 870 km (the perigee and 
apogee of the orbit). To extraoplate this data from the dynamic 
equatorial ionosphere at high altitudes to the worldwide ionosphere is 
not valid. Visit mysite/verizon.net/k9la/, click on the Timely Topics 
link at the top, and then read "Is the Ionosphere Really Lower?" for 
details.
