I am finding that PSAT is 6 MINUTES behind the predictions of the previously
provided original Launch TLE :

1 99993U          15140.67013889  .00040043  00000-0  10235-2 0 00009
2 99993 055.0004 339.9238 0251027 182.3314 074.3075 15.12517086000014

So until I get new ones.  Just point at AOS and wait 6 miuntes.

Also, I had said not to TX PSK31 on the 10m u plink until you heard the
downlink.  Well, that was dumb advise, because the transponder does not come
up unless it hears PSK31!

So the new rule is, Listen first.  If not heard, TX anyway.  If not heard
then, Fix your problem, and try again?

We don’t know how the power budget will work out.  So all we can do is
