And yes, please send along any corrections!!! The conversion factor for U hasn't changed in this one. The passband is wider in this chart than the previous one, based on info from the http://www.amsat-dl.org/journal/adljxpnd.htm web site. Also I've widened the "guard band" around the beacon to that site's "stay away" range (a bit wider than +/- 5 kHz). And I've included L-band as well. Can someone verify the frequencies as matching up with what the bird is really doing? (I'm not yet set up for permanent ops, so I can't verify right now myself.) I compared the downlink/L-band uplink to Rolf's (DK2ZF) QSOs he posted, and it agrees +/- 5 to 9 kHz (which I figure is attributable to doppler). Any verifications for the U uplink? This chart doesn't line up very well in my email editor, but the tabs appear to be there, separating the columns so it should come out in most cases.
