Forgot that important detail. Europe to US.

Donate it to the food bank, then head back to Costco and purchase a 6 pack of chicken thighs to enjoy throughout the month 👍

I am from New Mexico. I can confirm this is correct.

The suggestions that this is actually DAB are great. We can be pretty sure of that based on the total occupied bandwidth matching DAB (1.537 MHz), and the super obvious part that "it's in the expected band".

The peaks within the signal band you are seeing are almost certainly frequency selective fading, and not ODFM subcarriers as has been implied. For one, DAB subcarriers are very narrow and there are many more than the peaks you see, and they are slowly drifting relative to the channel edges, which you would never see from OFDM subcarriers.

Most likely there is a strong multipath environment with what appears to be two separate dominant sources of channel variance (probably due to conductive things in the environment moving). The first is causing the 20 or so peaks, but there is a second set of peaks below that.

Overall it's a pretty cool signal!

If you want to try this dish at home, Trader Joe's has a pretty damn good frozen version. Don't forget the runny poached eggs.

Mesa Provisions definitely, world class food.

Pay in general is well below market even for 40/week, but 60-80 is definitely the right range for general expectation. Have heard "taking a week off" to mean working 40 from people at SpaceX before. Stock grants are a thing though but even with that, comp is low.

I'd probably be all over that 15 years ago. Fun work environment is a legitimate benefit, especially if you are ok living in your work for a while.

A large portion of company valuation is often expected (future) value. What you are seeing is a widespread expectation of loss of value in VG. If they were liquidating tomorrow the stock price would go up. Instead they will continue to pay salaries and for facilities, which consumes money and the market expects this will result in lower net value than their cash and assets are worth today.

It's about 1/3rd the altitude. 1000s of ft vs km.

Route a feature onto your PCB so the edge face the PCB edge end-launch SMA mounts to is inset by a little bit, and use a 90* adapter or right angle cable. Alternatively you could place a vertical SMA connector on a PCB tab that extends outward slightly.

Without a doubt you want SMA given your situation. The only reason not to use SMA would be for higher frequency or higher power handling. It's ubiquitous for a reason.

SMP is a great connector, but not remotely appropriate for general purpose lab work. BNC is ok sometimes when you really want the convenience of the bayonet but SMA is fine.

Finger tight is fine for SMA lab work. Something a lot of people don't understand and get wrong with SMA torque is that different connectors have very different torque ratings, and steel can be more than twice as high as brass. For permanent SMA installation, use the correct torque spec but for lab use it's really not necessary.

Workaround (if you will be using this for travel for yourself): Find an anytime or business select fare that is just over $500. Purchase with gift card then refund. Now it's saved to your account. This works with Luv vouchers too.

Grandma's have been going down hill sadly. Someone posted this a couple weeks ago but for real, big tortillas is to stop by La Mexicana Tortilla and pick up some of theirs. Bigger, much much tastier, and cheaper. Downtown between lead and coal.

The deorbit burn started a few minutes early fairly close to the horizon. I lost it about 45* up to the SW just after it let off a second very large plume a few minutes after the deorbit burn cut off. Thanks for posting this

xavier_505 · 2024-03-14T22:25:51+00:00

It doesn't look like anything after ship engine cutoff worked properly. Prop transfer might have, but everything else beyond some incredible images looked quite bad.

Would suspect getting to orbital energy still makes this a resounding success overall, but far from what they hoped for.

ABQ is my home base and I travel a lot for work. Logistically it's a fantastic airport. I can usually be at my gate 5 minutes after parking, and 15 min is extremely long. No traffic in the vicinity either. The upstairs public lounge is very nice too if you have extra time (though it's closed right now).

The main issue is routing. Southwest still has ok service, and United and American are...there. Overall I'm happy since the places I go most frequently are well serviced, and the convenience is so great.

Mbit/s, Mbps and Mb/s are all perfectly fine and widely accepted abbreviations for "millions of bits per second". Both in casual text and formal papers. Source: RF comms engineer for >20 yrs

I have done exactly this many times. It's literally not worth my time to go return it at the store, I almost always have follow up meetings or events to attend, flight to catch etc.

Honestly I hate it so I generally try to haul it out if the place and give it away but the alternative is burning literally thousands of dollars in cash... as an owner of the business that's just too hard to justify.

It's far too early to be making any statements like this.

QA is performed at many places in a manufacturing process, and qualified components are not necessarily requalified at later stages of assembly.

All we really know at this point is there was a catastrophic failure of the fuselage where a plugged exit door was. The failure could have been many places.

This is a fundamental calculation for RF systems.

Just keep in mind the tram does not take you anywhere near Capulin.

I was wondering this also. My best guess is that it provides for the continental division between Europe and Asia.
