Yes, PCSAT is coming over in the mornings local sun time and in
3 days when it is about an hour earlier, then it will be close
enough to sunrise and sunset to be in full sun 24/7.  At that
time, we can send the recovery commands and everyone will get
access to PCSAT for several weeks.

The default is to have them on (we wont make that mistake
again).  But they contain no real text, other than something
like "default L-text"...

So once we recover PCSAT, we will load those with meaningful
beacons.
Since those beacons are on 144.39, every mobile in the country
has a chance of seeing them now that the New-N paradigm keeps
the frequency quiet enough...

> Four Beacons in  6 seconds looks like a bit much. 

You got that right.  They are spaced out about 4, 5 and 6
minutes., but unfortunately the FIRST packet after booting up
are quite close.  We wont make that mistake again next time
either... Since PCSAAT is resetting on every orbit! (until we
get to full sun)...
