Puzzling indeed. Is there evidence that they transmit all the time, and not just above some ground station near yours ? I'm not sure whether figure 2 shows RF sightings or just the orbital planes.

Hmm, technically can't they increase capacity simply by launching larger phased arrays and/or moving to shorter wavelengths ? Their next-gen satellites are rumored to be 2000 kg (vs 260 kg for the first constellation). Whether this makes economic sense is another debate.

Back in my day when the sysadmin managed load-balancers, firewalls, computers, storage, backups, HTTP daemons and back-end databases, and users provided the business logic, it was called CGI scripting :-) Today, FAAS or Serverless ? As in AWS Lamba or Google Cloud Functions.

Probably coming from this 5 W SSPA SDR modem. www.vulcanwireless.com/nsr-sdr-x/s

My first guess was particle physics, but then considering your published work I thought it could also be orbital mechanics :-)

Either that, or the copper gauge is thinner in that wire :-)
