wonder how many of these we could have had (with maybe an AO-10 or two thrown in) for the dollars spent on AO-40?

It really does sound pretty cool. I'm already looking forward to chasing it across the sky with my handheld!

This sounds like a nearly ideal LEO satellite.

An FM cross band repeater to get newcomers to use the satellite without new investments.

A linear transponder for more serious work that the FM ops can move up to. It seems to me that when the FM ops see what others are doing with the linear transponder on the same satellite it will be a good incentive to move up. More QSOs, better DX, less QRM.

And a digital transponder for those so inclined.

Kind of one stop shopping.

It could be a bit higher, but one can't hope for everything. - Duffey

Hi Trevor,

Aaah good! I guess I missed it since the name was listed as CAMSAT and XM-1 was in the text.

I'm very pleased that the IARU coordination process is being followed by our fellow Chinese Amateur satellite enthusiasts.

I hope they'll get a better break on launch costs then what we're faced with.

Michael, we'll all being looking forward to continued progress reports and will be wishing for their success.

Regards...Bill - N6GHz

A quick check of the IARU satellite frequency coordination web site doesn't shown XW-1 as being in the coordination process.

Hi Bill,

It's on the co-ordination pages at
