Between you ord # and living in Wisconsin I think you should have gotten it by now
is there any rhyme or reason to the madness.
LOL
We’re you given an approximation when you would get your dish? I was given mid to end of 2021
Latest update that SpaceX gave the FCC. SpaceX says Starlink has about 90,000 users as the internet service gains subscribers
plus the little blip in the article that they could launch 400 at a time with the Starship

It would make a lot of sense to me for mobile purposes. Such as putting it on top of an RV or private "bus" vehicle especially when getting to a location at night to use it. I've certainly seen bigger things on rec & tour vehicles. But on a car? yup, that would look strange.I'm going with Funny on that one - Funny as in the driver, the person that decided to attach a starlink dish to their car

good post about the 2nd gen dishy on reddit
"The second generation is elliptical. See E33/34 field: 0.29 m minor and 0.48 m major diameter. That's the dimensions of the antenna radiating elements not its housing."
meaning the internals have an oval layout but we don't know if the dish will still have a circular housing or not.

3 weeks later and almost all the gaps are filled in, today I realized the proper spacing is every 5 degrees and the bottom bar chart should only have 72 bars if sats were all in final positions. As of this morning there were 6 bars out of position mostly with one sat each. The actual gaps in the top portion of the image are a better representation of actual gaps in service.
I didn't mark all of them but notice how the short bar that looks like a huge gap near 260 is really just one sat sitting between two basically full orbits, not an actual huge gap in service like the mostly empty bar implies.
The one big gap is around 141 and a single launch would provide enough sats to fill that and then some.

Interesting. Caveat that I am in no way an antenna person let alone a phased array person, but this, In general:
1. Reduces the number of radiating elements
2. Reduces the number of unique beams that can be formed
3. Reduces the beam forming processing required
4. Increases the size of each beam
5. Changes the shape of each beam from ~conical to ~elliptical
6. Reduces the FOV/half angle is the array (can see less sky)
I would guess that #3 is most important here—the number of elements is likely ~linearly proportional to the processing (and effectively, the number of processors), and the beam forming chips (ASICs, IIRC) are almost certainly the most expensive line item on the BOM. So, fewer chips = lower cost. It’s unlikely this also enables them to drop in an ~OTS fpga, but opening that option up as a result of lower processing demand would manifest as even lower cost.
The downside of fewer and larger beams is likely a minimal issue (that’s rather self-evident since it’s what they’re doing) but theoretically that means each of the UT beams will see more sky and, importantly relative to my speculation here, a higher probability of more satellites in each beam. To be clear I have no idea what their frequency reuse plan or protocol actually is so, again, heavy speculation here, but in general this phenomenon would likely lead to lower user throughput.
Flip side, while the smaller FOV/half angle of the array means it can’t look at low elevation satellites, that’s also the worst case geometry for seeing more sats/beam and the hardest to form useful beams. Low angles are also the most ranging loss (and so, theoretically the hardest to maximize throughput)…so…from an abstracted ‘value to the system’ perspective, those low angle geometries are exactly what you’d eliminate first if you were trying to iterate for total system efficiency. Clever.

The reddit hive mind feels my last statement there is misleading as there are already enough sats from the May 2021 launches to fill those gaps.
The number of gaps is less than 60 so if you use one launch as a unit of measurement to mean 60, then my statement stands with a different connotation, they don't have to launch any more sats, but if they did "a single launch would provide enough sats to fill that and then some."
The point wasn't to say they need to launch more sats ASAP, the point was to compare how close to a full first shell they are. Out of thousands of positions filled they have less than 60 to go.

Seems that a major reason for the amendment is that when they start to use Starship to loft Starlinks they want to use different orbital configurations to take advantage of Starship’s capabilities.

Covid hospital cases are preventing SpaceX from launching as many rockets as they would like. SpaceX can't buy enough oxygen because it's being used for covid patients.
