D-Star

I was reading the July edition of Monitoring Monthly and came across an article by Paul Marsh. In it he mentioned a home-brew D-Star transciever designed and built by Moe, AE4JY and detailed here. Thanks for the info Paul, kudos to Moe and his buddies for a very interesting prototype and some excellent information. Is it the future of Amateur Radio? who knows, but the work done my Moe, his buddies, and others like them will definitely shape it.

Killarney

Dee and I made a last minute decision to head for Killarney for the weekend. What a fantastic weekend it was. After we arrived on Saturday afternoon we wandered up Torc Mountain. After dinner I suggest that we attempt Mangerton on Sunday morning.
Maybe it was the wine or the weather, but Dee agreed, and we had a fantastic day in the hills.

Work work work.

Wow, what a busy two weeks. I spent last week preparing for the GAISS field trial. Which was reasonably succesful, though I’m knackered after it. I was also acting as “Net Control” for the “Base” VHF/UHF Radio Station that we had set up for the weekend. Technically I had the easy job as I wasn’t actually walking, though I was wearing ‘many hats’ for the weekend (WIT/AREN/TARG).

Scott N1VG’s prototype OT2’s and T2-135’s worked very well over the weekend. And we had better voice communications than previous years, so we will call it a success on all fronts. I have a few pictures available here, most of the pics were supplied by others.

Back in the ‘salt mines’, several things went wrong this week. Came in on Tuesday to find both drives in a mirrored raid array had failed, thankfully we didn’t have too much on the drives, but it just goes to show, it can , and does happen. The best thing to come out of that was we re-checked that all our project data is being backed up properly. Then, last night, I was trying to access some IPv6 only sites from my home network (to test a SHIM6 enabled server in work), no joy. The laptop wasn’t getting the radvd advertised prefix. Checking it out, radvd is giving me an error:

radvd[8411]: sendmsg: Invalid argument

As a quick test, I downloaded the latest version of radvd, same problem, my guess now is that it is a kernel (2.6.17.10) issue. It will have to wait until after the weekend, or SWMBO will shoot me.

Now, I think I’ll try and catch an hours sleep before the STS-117 launch later on this evening. About 20 minutes after launch, it should be possible to hear voice communications on their downlink frequency of 259.7MHz AM.
