Very clean, strong signal here in CM98 just now on an overhead pass. I
didn't have a chance to configure the automation, so tuning 70cm Doppler
by hand while trying to copy CW with FLDIGI. Not much decoded, but I
did see "NEXUS" among the gibberish.
Congrats!

With an unexpected new TLE set published, NEXUS now has a slightly
better match with object 43940, 2019-003J. Apparently TLEs have not
yet stabilized.

Illegal? Depends on the ITU region it is flying over.
U.S. 47 CFR 97.207(c)(1) defines 435-438 MHz as the allowable transmit
frequencies for space stations. However, the ITU just marks 432-438 as
AMATEUR (primary region 1) or Amateur (secondary regions 2&3). No
distinction is made for amateur-satellite stations.
The ITU does allocate this swath of spectrum to "Earth
exploration-satellite (active)". I haven't dug into that.
Unfriendly and uncoordinated? Definitely.

Remember to check the RR 5.282.
RR 5.282 In the bands 435-438MHz, 1260-1270MHz, 2400-2450MHz, 3400-3410MHz
(in Regions2 and3 only) and 5650-5670MHz, the amateur-satellite service may
operate subject to not causing harmful interference to other services
operating in accordance with the Table (see No. 5.43). Administrations
authorizing such use shall ensure that any harmful interference caused by
emissions from a station in the amateur-satellite service is immediately
eliminated in accordance with the provisions of No. 25.11. The use of the
bands 1 260- 1 270 MHz and 5 650-5 670 MHz by the amateur-satellite service
is limited to the Earth-to-space direction.
The amateur-satellite service is available world-wide in the band 435-438
MHzn on a non-interference basis.

Art-
Good point, but does the telemetry on the CZ-4B use an amateur radio
callsign? If not, then perhaps it is part of the China aeronautical
radio-navigation service:
5.279A "The use of the frequency band 432-438 MHz by sensors in the
Earth exploration-satellite service (active) shall be in accordance with
Recommendation ITU-R SA.1260-1. Additionally, the Earth
exploration-satellite service (active) in the frequency band 432-438 MHz
shall not cause harmful interference to the aeronautical radionavigation
service in China."
I'm certainly not defending the use of our spectrum for commercial
telemetry, but both China (region 3) and the USA (region 2) are in the
Amateur secondary allocation on 70cm. We have to expect some
interference on this band.

If the telemetry qualifies in the amateur-satellite service, all?s well.
Lots of possibilities exist for making this workable. Need details to know.
