Loren,
for ITASAT-1 (1k2 BPSK) use UZ7HO soundmodem
http://uz7.ho.ua/packetradio.htm -> other-versions.zip
You can also use MixW or Warbler

for MOVE-II (12k5 BPSK) see more information and decoder here:

Betreff: [amsat-bb] Decoding the new AX.25 packet satellites
I have several raw IQ captures from last few days with the new satellites
passing and am trying to decode the AX.25 packets from two of them. I'm
using SDRSharp to reply them and pull the signals out using USB mode. I've
already replayed them successfully and decoded both JY1-Sat and AO-95 using
their respective software packages, but I'm having trouble figuring out
ITASAT and MOVE-2. I'm using Virtual Audio Cable to loop back the audio and
UZ7HO Sound modem in an attempt to decode them. For ITASAT, it's set to 1200
bps BPSK and for MOVE-2, I'm using the 9600 baud variant of BPSK Sound modem
from his site. However, efforts have been fruitless to get it to resolve any
packets. Any pointers for these satellites would be appreciated.
