Hi,
A DNS change has occurred that is pointing data.amsat-uk.org to another
machine.
http://warehouse.funcube.org.uk is an alias and is working fine.
I am trying to find out who did it and change it back.

Thank you to everyone attending San Diego Microwave Group's 29 June 2020
Zoom meetup. Part of the discussion was about the possibility of the AREx
broadband digital microwave design being potentially deployed on the
International Space Station.
Since we've focused heavily on high earth orbit, geostationary orbit, and
the lunar opportunity with Gateway, the challenges of low earth orbit (ISS)
now need to be addressed. This will be an ongoing process. Here's what
participants recommended at SDMG:
Since there are LEO constellations up to and including Ka band, the
tracking and doppler have been done. It's just a question of learning the
requirements, design patterns, limitations, and techniques.
We already incorporate the near-space communications recommendations from
CCSDS, so we're in good shape there.
HamTV on ISS is at 2.4 GHz, which while lower than our 5/10 GHz, has all
the other aspects of broadband digital. There is plenty to be learned from
there, and meetings are being set up to begin to collaborate with the
principals of HamTV on deeply appreciated advice & next steps.
Strong advice to eliminate antenna pointing. Use an antenna system in space
and on the ground that does not require tracking, and that would
dramatically increase adoption.
With Adaptive Coding and Modulation, all sorts of systems can be
accommodated.
Meaning, a ground station that does track can use a directional antenna
with a lot more gain, and get a much higher bitrate, while a station with a
120 degree field of view would get a lower bitrate, but would not have to
track at LEO. This needs thorough link budgeting.
We have several link budgets in Jupyter Notebook in progress at
https://github.com/phase4space/payload-dmt
If you are interested in helping here, welcome aboard.
Testing for human rated spacecraft incurs a substantial increase in
engineering, paperwork, and time requirements.
Putting the equipment outside instead of inside does not eliminate the
testing requirements. This is going to require advice/direction from ARISS.
Space heritage of this type, where we are an external payload only
requiring power, makes hosted payload options easier to negotiate. There
are 5-6 GEO missions going up in the next 3 years that we could and should
target.
Doppler is a factor here, and we received strong recommendations about
talking with particular ARISS team members with experience. We will be
learning from and incorporating their advice in the very near future.
Thank you all for supporting this project and being generous with your
time, talent, and treasure. We are making excellent progress while
providing all of our work to the general public, with AMSAT as a primary
beneficiary, at no cost.
Next meeting scheduled is an AREx technical team followup (from last
Thursdays ARISS International review) on Thursday 2 July 2020.

There will be a slight delay in both processing submissions and replying to
email submissions.
My computer SSD drive died during the night. Everything is backed up to NAS
hourly and should not have lost anything.
Will try the cloned drive first and then restore the latest files.
Of course with an 8-10 year old PC this is a wonderful opportunity to
upgrade to a newer PC.
I do not like responding I received your submission from my phone because if
there is an issue loading it on the PC then you will not be included. I
always make sure it is on the PC first.

I removed the crashed drive, installed the cloned drive from April and
everything booted. Reinstalled the crashed drive and was able to look at
all the files, just not boot from it. Moved all my files and databases
over and everything is back to normal. Wasted a couple hours but so much
better than wasting days.
Copied all the files for my email client and everything is as it was.
Nothing lost.

The weather at Mahia is not looking good for the next few days.
I did think they might have got a short slot tomorrow but not so.

I have an older orange case SSB2000 model preamp. I used to use it for EME
but replaced it and now want to use it in another installation for
satellites. I do not however want to power it separately and want to send
power down coax with ft847. This does not seem to work and I?m wondering if
I need to make some sort of internal change to the preamp. The manual
suggests I can power it through the coax. Any thoughts?
