LOTW
by Jim Bennett 22 Jan '11

22 Jan '11

I have been using LOTW and eQSL for over a year now. And it appears some are just entering their contacts now since it supports VUCC. I enter my contacts manually and sometimes I make a mistake when transferring from paper to electronic. So if anyone gets a rejection of my call, don't hesitate to drop me an email. Jim KE4KOL

Looks like the volunteer card counter does all the work for FREE and the ARRL gets the spoils WA4hfn

Hallo I found possibility of Doppler correction in TS 2000 split mode. Very usefull during ISS/ARISS contacts. Here is short description: http://www.enduro.idl.pl/TS_2000_soft/ts2000.htm Matt SQ7DQX

ISS ground digi
by Andrew Rich 22 Jan '11

22 Jan '11

Perhaps one of the smart guys that make TNC"s from uP can include some search and replace code in the digi path ? Add another option "Satellite SGATE DIGI" Search for "SGATE" replace with "WIDE2-1" or preserve the "SGATE" as well. Maybe a satellite "robot" can be made like I did years ago with a PIC chip It listened for "SGATE" to come in on the serial line , (ie satellite in range) and the TX for 10 minutes every minute then went back to sleep. Maybe we need to launch a satellite that "triggers" ground stations, and then relays the list ? The ground unit could be considered a "transponder" itself. Maybe the sat could have some smarts and "POLL" heard ground stations ? Maybe the ground transponders could have a "lock" light. I see the ground device as being a simple radio and a uP style TNC Just a few ideas. The best satellite I liked was dove i thnk its was ? Just straight packet down ? What would be cool is a satellite that sends it position LAT and LON.

I can work out the frequency bit, thats fine. It the downlink path I am having issues working out. ISS only have SGATE How do you make the "go further" than just "SGATE" How can you turn RS0ISS-4>CQ,SGATE:>ARISS - International Space Station (BBS/APRS on) into RS0ISS-4>CQ,SGATE,<another digi>, <another digi>:>ARISS - International Space Station (BBS/APRS on) Perhaps a simple cross band VF repeater might be the trick ?

Never mind, LOTW already works with HO-68, just needed to update my config.tq6 file.

Video: very low bitrate digital voice communications
by Bruce Robertson 22 Jan '11

22 Jan '11

I'm sure many of you are very interested in the current state of Codec2, the open-source, low-bitrate voice codec that is being led by David Rowe VK5DGR. If so, I'd like to draw your attention to the following video that ZL3IN and I made over the past weekend, which comprises the actual audio of our first meeting over the Internet, using codec2 bitstreams. I hope you'll agree that this alpha-level software is very usable right now: http://www.youtube.com/watch?v=_k-nhHE6CrI Our conversation was conducted using a bash script that I wrote to provide simple codec2 voice communication over the Internet. Since October, I've been spending what would normally be my ham time working on that, or trying to help improve the c2 performance on low-power CPUs. Codec2 could be very important to AMSAT's future. Running currently at 2500 bps, and aiming for 2400 bps with FEC, it could make satellite voice communication comprise a smaller bandwidth, offering less demanding downlink systems. Because it is open source, the codec could even be implemented in the satellite, perhaps to provide voice-encoded telemetry for a FUNcube-like project of the future. The Codec2 site is http://www.rowetel.com/blog/?page_id=452 The source files of my conversation with ZL3IN, and many ancillary c2 materials are available on my blog: http://ve9qrp.blogspot.com 73, Bruce VE9QRP
