The satellite might have failed and is now inactive:

The BBC quotes an SSTL engineer as saying It was too early to say that the
satellite was dead. He stressed that any spacecraft would be unstable
immediately after launch, and that North Korea could be trying to rectify
the problem.
"We take typically two or three days to get a satellite stable, and we know
what we're doing - whereas this is the North Koreans' first try.
"It would be prudent to wait a little longer and monitor the tumble rate to
see whether there's any attempt to stabilise it."

I've been using the following for portable sat ops using only my Nexus 7 &
Nexus One.
- HamSatDroid
- GPS Status
- QTH Locator (works great for storing positions when your out!)
This combo worked great while I was in Scotland in the summer!

But they exchanged a QSL and both got the original exchange info from each
other.
On a shared single channel resource, we should be concerned with contact
efficiency.
This takes 16 packets for 8x8 or a total of 64 confirmed contacts. 2N for
N*N contacts
Compared to 256 packets for 64 confirmed contacts the analog way (4*N*N)
Or compared to the impossible 2560 retries trying to do it via the ISS
BBS!
