All emissions on those channels are FM. 73 de Dave, NF2G

Thanks Dave, is it via some sort of data burst? On Wed, Jul 29, 2009 at 10:30 AM, nf2g d...@nf2g.com wrote: All emissions on those channels are FM. 73 de Dave, NF2G __._,
[digitalradio] CQ Hawaii
I need a LOTW verified QSO with a station in Hawaii via any valid digital mode . This is all I need to accomplished the ARRL LOTW Triple Play award. Any Hawaii stations on this list ?

I use a docking station that allows you to drop a SATA drive into it, and it acts just like another hard drive on the system. it plugs into the computer via a USB line, and has an external power supply to get the +5 and +12 to spin the drive. This model of dock also has memory card slots and 2 additional USB ports for memory sticks. I use it to reformat and image drives at work, and to read the memory cards of the different cameras that everyone uses. Most of our tech staff has portable drives made from laptop drives put into an external USB enclosure. Not the cheap way to go, but it was more cost efficient at the time.

Access via USB is significantly slower than native IDE access, but you can connect to any PC with a USB interface; perhaps they have a USB 2.0 version by now: http://www.addonics.com/products/io/ While converters like these are somewhat slow, they allow you to connect a drive up to a running PC -- eliminating the need to power it down, open its chassis, and make the IDE or SATA connection -- which can be difficult in a smaller chassis stuffed with cables.

They are not normal FM transmissions. AIS uses an emission designator of 16K0FD. More specifically, a 9.6kbps GMSK FM modulation using HDLC packet protocols.

Looks like AX.25 9600 packet by a different anme. Anyone know if the G3RUH modem decodes it ? 73 Trevor M5AKA

Hi All...have tried to see if Shipplotter will run on Linux under Wine have got the GUI up and it seems as if may be working ok. havent got the hardware to fully try it out. 73 David VK4BDJ aa777888athotmaildotcom wrote: Google is your friend.

[digitalradio] New FX.25 Protocol - Amateur Radio Satellite Experiment
ANDE due for deployment from the Space Shuttle tomorrow will experiment with the FX.25 protocol. Based on the 1980's AX.25 standard the new FX.25 features forward error correction. ANDE FX.25 Protocol Experiment https://goby.nrl.navy.mil/ANDE/Amateur_Radio.html Four Amateur Radio satellites are to be deployed from the Space Shuttle mission STS-127 on Thursday July 30 The satellites are ANDE Castor, ANDE Pollux, BEVO1 and AggieSat2. They will be deployed from the space shuttle Endeavour (STS-127) at 7:27 am CDT via the Space Shuttle Picosatellite Launcher (SSPL). You can follow AggieSat2 on Twitter at http://twitter.com/aggiesat2 ANDE Castor - 145.825 MHz FM transmits telemetry every 30 seconds https://goby.nrl.navy.mil/ANDE/Castor.html ANDE Pollux - 145.825 MHz FM transmits telemetry every 33 seconds https://goby.nrl.navy.mil/ANDE/Pollux.html BEVO1 (DragonSat 1) - 437.325 MHz FM, Morse Code at about 20 WPM http://www.utexas.edu/news/2009/06/09/picosatellite/ AggieSat2 (DragonSat 2) - 436.250 MHz http://209.85.229.132/search?q=cache:FMerJChhzs4J:aggiesat.org/+aggiesatcd=1hl=enct=clnkgl=uk 73 Trevor M5AKA RSS Daily Radio News: http://www.southgatearc.org/ Daily News via Email: http://www.feedburner.com/fb/a/emailverifySubmit?feedId=2783644loc=en_US Submit your news: http://www.southgatearc..org/news/your_news_1.htm or email editor at southgatearc.org
