We have multiple digital Talk-groups and Reflectors, for Amsat, so drop on in and say hi sometime.
Ie..
DMR Amsat-98006
YSF-Fusion US-Amsat-11689
Dstar DCSSAT, REFSAT, XRFSAT, XLXSAT all on Module C
We have DMR and YSF bridged together currently, but the DSTAR is not linked into the bridge just yet, but still planning to do so.
Catch you there before too long.

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

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.
00:00 My setup 00:48 Demonstration 03:44 Background on HO-113 04:41 weak downlink, high SWR? 06:03 Real reasons for weak downlink 06:48 Deaf receiver 07:28 Noisy passband
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.
