Hi Les,
... AMSAT Journal (March/April 2013). Can anyone tell me if a later issue has shipped yet ...
The AMSAT Journal comes out 6 times a year. The schedule is January/February, March/April, May/June, July/August, September/October, and November/December.
The May/June issue was at the print shop 10 days ago, likely the post office by now. So hopefully you will see it arrive soon. You can see a preview of the May/June issue on-line at: http://ww2.amsat.org/?p=651
The July/August issue is currently being put together so it appears we'll be on schedule for that too.
Quick note for everyone: The Journal welcomes your input about everything related to amateur radio in space. Please send your articles, photos, operating tips, or announcements to the magazine's in-box at journal@amsat.org or you can send it directly to me.
