Yeppers,
I am there all the time.
I'm sure we'll catch up there soon, or on one of the many birds as well. 😊

Thanks, Walter!
I recognize your callsign from the AMSAT Brandmeister DMR node, which I've recently started monitoring.

Subject: [AMSAT-BB] [Video] New linear satellite HO-113 and its issues
Watch me work this new linear satellite HO-113 / XW-3 and talk about
some of its issues so you can learn how to work it successfully
despite those issues.

03:44 Background on HO-113

On December 25th, while most of the space community was excitedly
discussing the James Webb Space Telescope (JWST) launch of that
morning, the amateur radio satellite community was also anticipating
their own new satellite launching that evening.
On December 26th at 03:11 UTC, XW-3 (CAS-9), was launched on a CZ-4C
launch vehicle from the Taiyuan Satellite Launch Center in China,
piggybacked with the ZY-1(02E) earth observation satellite.
XW-3 was designated HO-113 by AMSAT a few days after launch.
