The other choice is the Kenwood TH-D7(g).  In additoiin to FM
voice, it can also do APRS packet via satellite with the
built-in APRS TNC and displays.

Next month, ANDE and RAFT amateur Satellites will be launched on
the space shuttle and both not only carry an APRS digipeater for
HT to HT digipeating, but they also carry a packet-to-voice
synthesizer.  This means you will be able to enter a text APRS
message into your TH-D7(g) HT and when the ANDE or RAFT pass
over, and your packet is successful, then the satellite will
SPEAK your message.

This mode was designed to let those with only an HT (without
APRS) at least hear something besides packets when doing a
school demo of these satellites.

Two caveats however:

1) ANDE goes to sleep when not in use, and each wakeup starts
the pass with defaults.  Thus someone on the West coast will
have to logon and activate the Voice Synthesizer.  Also ANDE
runs on dry-cells only and so we want to limit battery usage to
last as long as we can.

2) RAFT is only a 5" cubesat and its solar panels cannot support
this VOICE FM downlink very long.  So we will have to play this
by ear.
