Thanks everyone who has responded. If you emailed me personally, I hope I
have gotten back to you already (otherwise, please try to send again in a
way my filter won't catch). For those that cc'd the list:
John - Thanks for the link, I'll look through it as soon as possible.
Henk - Thanks for the dk3wn website, it looks like it has a lot of good
stuff (almost overwhelming).
Can I assume MSK=GMSK? I thought they were different, but they are the same,
and since MixW has MSK, and I could use that with a Rigblaster, etc, right?

The Vienna Wireless Society (Virginia) is planning our 8th
amateur radio balloon flight on May 1st. Info on previous
flights can be found at
http://www.viennawireless.org/balloon/index.php. WWS-8 is
probably a 1200 gram balloon with 2m and 70cm APRS carried by a
single 2-3 pound payload.

Hi Nate,
I was not aware MixW had MSK in it but still identical to GMSK. Perhaps
you are thinking of MFSK? In the MixW program there is MSFK16, a
multitone frequency shift signal, is supported, but not Minimum Shift
Keying or Gaussian Minimum Shift Keying signals. And also FSK, aka RTTY.
There is work going on to make a sound card 4800 bps 0.5 time-bandwidth
product GMSK soundcard modems for use in GMSK DV adapters to use with
D-STAR radios. Perhaps that could be adapted for your purpose?
http://www.qsl.net/kb9mwr/projects/voip/dstar/G4KLX.html seems to
describe some of the work.
http://groups.yahoo.com/group/dstar_development/ and
ttp://groups.yahoo.com/group/pcrepeatercontroller/ are where I see the
discussion underway.
Separate discussion is using an external sound card interface like the
Rigblaster, to connect a computer and radio.

Hi Nate,
Sorry for the long delay....
MixW doesn't support GMSK. You mix that with MFSK.
BeeSat has two CMX909B modems (CML) onboard. The data is sent in the MOBITEX
format, not AX.25 !
See here for more information about Mobitex:
http://en.wikipedia.org/wiki/Mobitex
The CMX909B is a half-duplex Gaussian Minimum Shift Keyed (GMSK) BT = 0.3
modem data pump with on-chip packet data handling. GMSK modulation optimises
the data throughput for a given bandwidth RF channel and the on-chip packet
data handling relieves the host ?C of regular processing tasks, such as
maintaining Bit and Frame Synchronisation, Block Formatting, CRC and FEC
Error Processing, Data Interleaving and Scrambling.

Hi All,
I've pasted a recent post from the IceBridge Twitter link at the end
of this email. It helps one to appreciate the conditions under which
Reid, OX/N0RC is operating when he's standing outdoors with his HT and
Arrow looking for QSOs on AO-51 or HO-68 from FQ56.
Thanks Reid!
