They may be in space, but the transponders have not been activated. So yes, someone bothers.

I heard about the new satellites launched from China, which
includes many transponders.
For long time I have not been active anymore due to
private reasons, but this great news triggered me to check the news again.

is great to see that transponder activities grow, but at the same time I feel
that amateur spirit is gone when even international bandplans are violated on
large scale. When I read the AMSAT-BB threats it seems that nobody bothers at

In the past there were many discussions about AO-7 downlink that is
outside the satellite band, while it was due to regulation change after launch.
This was outside to hands of the satellite builders. Now we have satellites that
work outside the satellite bandplan even known before launch. This is tolerated
When this is tolerated then my next transponder design will be much easier
to design for me.... 

I hope that someone at CAMSAT will do something about
this, and I wonder why they allow this to happen at all...
>From technical point
off view, great work and continue with making amateur satellites (ofcourse
inside the satellite bandplan).
