[amsat-bb] Re: BeeSat at 4800 GMSK
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. 73, Tom n4zpt Nathaniel S. Parsons wrote: > Can I assume MSK=GMSK?

[amsat-bb] FW: Amateur Radio High Altitude Ballooning
Tracking two APRS balloons! (one on the east coast!) Sent: Thursday, April 08, 2010 12:14 PM Subject: Re: Amateur Radio High Altitude Ballooning 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.

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? -Nate On Tue, Apr 6, 2010 at 3:17 PM, John B.
