[amsat-bb] CAS-6/TIANQIN-1 TT&C Frequency or Object Number?

Hi all,

>From this article, it looks like the CAS-6 payload V/UHF antennas on
TIANQIN-1 haven't yet been deployed:

I'm wondering if TIANQIN-1 is beaconing on any other frequency? Clearly the
controllers are getting data from the sat somehow.

I have identified a few objects from the same launch transmitting on the
400-403 MHz TT&C band, though none of these have been named in the
catalogues (as seems to be typical for Chinese launches). In particular, I
have seen:
Object 44884 - 401.548 MHz
Object 44886 - 401.951 MHz (This is apparently a rocket body)
Object 44887 - 401.951 MHz
Object 44889 - 401.750 MHz

I'm wondering if any of these are TIANQIN-1 .. if the operators of the sat
have an object number, it would be great if they could share it, so we can
at least point our antennas in the right direction!
