Aloha··on Why does FM sound better than AM?
I’d have to figure out how to yank the board.

It’s tight.

Aloha··on Why does FM sound better than AM?
12 kHz AM on a good receiver sounds absolutely fantastic.

I have a Royal 51/810 (one of each) that I use as a travel/bathroom radio, ironically, both have fantastic AM performance, and.. lacking FM - the IF/Audio bandwidth appears twice as wide on AM, and FM just sounds like crunchy - probably needs caps in the audio section, but its so tightly packed, and has a PCB with the heaviest plating I've ever seen - which means it needs work I cannot easily do.

Needed an emphasis curve applied to it.
Aloha··on Congress fights to keep AM radio in cars
No, but they would to avoid customer complaints at the dealer level - I dont think its a huge cost to add needed filtering.
Aloha··on Congress fights to keep AM radio in cars
My belief? yes, it does. The motor controllers are noisy.
Aloha··on Congress fights to keep AM radio in cars
"Several automakers, most notably Tesla and Ford, have decided to stop putting AM radios in their electric vehicles. They claim their electric motors interfere with the audio quality of the signal and insist that FM and satellite radio are enough."

I can find other references as well if you want. EMI in cars has been an issue for a long time, automakers however did do the needed work suppress the noise from spark plugs, I do not see this as any different.

Aloha··on Congress fights to keep AM radio in cars
The cost isn't in the radio, you have a single chip which is a complete AM/FM radio - the cost is in making cars quiet enough from an EMI point of view - something which, IMO, they should have to do anyhow to comply with Part 15.
Aloha··on Congress fights to keep AM radio in cars
We mandated UHF channel reception for televisions (https://en.wikipedia.org/wiki/All-Channel_Receiver_Act)

I believe that mandating AM reception is perfectly reasonable - as the reason given for leaving it out is because auto manufacturers do not want to spend the money to reduce the EMI from their vehicles.

The total added BOM cost to add AM to a modern radio is zero - because they have a single chip that does both AM/FM.

Aloha··on Congress fights to keep AM radio in cars
Right, but digital radio is a small portion of the US market, and what IBOC stuff that did happen, much of it has been turned off.

So I dont really understand what this comment has to do with the article at hand here?

Aloha··on McDonald's says Tyson and other suppliers fixed beef prices
Interestingly enough, In-N-Out does do their own beef processing, they take whole sides of beef, and turn them into patties.
Aloha··on Filed: WP Engine Inc. v Automattic Inc. and Matthew Charles Mullenweg [pdf]
I moved to WPEngine from a self hosted job, money well spent.

I've never had a lick of trouble, and even though I'm pretty proficient at hosting LAMP apps, it's much less effort than self-hosting.

Aloha··on WP Engine sent "cease and desist" letter to Automattic
Which particular service of Automattic?

Like Wordpress.com in hindsight seems to offer it, but its not clear to me that I'm their customer target.

Aloha··on "Traffic Violence": The Grifters Go After Cars
Everything these days seems be some sort of violence.

I'd like a future where we're less car reliant, I think modern vehicles are dangerous to pedestrians - that does not make this some sort of violence however - violence implies an intent, and I dont think there is any provable intent here.

Aloha··on Bill limits smartphone use in California schools
Parents will howl at the local admin if its locally changeable policy - I suspect that the thought of being out of touch with their children is unbearable.
Aloha··on Bill limits smartphone use in California schools
I think this is great, phones (largely) should be banned in schools.
Aloha··on WP Engine sent “cease and desist” letter to Automattic
Disclaimer WP Engine Customer -

I read the comments from Matt M yesterday, and it felt like a hit piece.

I run a website for a couple scifi like conventions, we need cheap reliable hosting without me having to deal with the vagaries of running wordpress myself.

I would have bought a product like WP Engine directly from Automattic, but AFAIK they dont offer one, this feels like lashing out at a competitor because they failed to enter a market segment, and now feel their lunch is being ate.

I ran websites for a long time without any version control, and would have no problem doing it again, the benefit of WordPress is the semi-WYSIWYG editor and the plugin ecosystem.

Aloha··on Bricked iPhone 16 Can Be Restored Wirelessly Using Another iPhone
You would be amazed how many normal people dont have a computer - they have an iPad and an iPhone (or android similars), and yeah - its like that now.
Aloha··on Apple Watch sleep apnea detection gets FDA approval
What bothers me is that you need a prescription to get a mask for a CPAP - I kinda get the prescription needed for the CPAP - but the accessory mask - that just seems absurd to me.
Aloha··on Flipper Zero Gets Major Firmware Update, Can Eavesdrop on Walkie-Talkies
A lot of these issues if not all are specific P1 P25, which if you're on conventional you're using. I find it interesting they treat P1 as if it's different from normal FM, it is not, its C4FM - so all the normal capture effect stuff works fine.

In the end, the goal of P25 was to make it almost, but not completely possible to listen in - I'd also note the way they did their testing is not how these radios are typically deployed, which is not direct subscriber to subscriber on simplex, its either via a conventional repeated system or via a trunked system.

I do agree that frequent key changes are bad - but for entirely different reason, they're an operation nightmare. Most agencies who deploy it either use very long lived keys deployed by KVL, or deploy a UKEK and then change keys via OTAR on some cycle, which is not infrequently, never.

My belief is the theoretical risks on P25 are not well proven in reality, you're more likely to have some interference issue over say, intentional jamming.

Either way a radio for ~75 bucks plus supporting hardware that will do AES256 isnt bad - and DES-OFB/DES-XL is good enough to keep the casual listener out, which is more or less the point of the crypto here. Also I know they make a big deal about unit ID's, but they carry no meaningful info, its just a hex ID.

I'm using EFJ 5100's and have a full KVL, and software that can make Christmas Tree radios.

P25 Encryption is pretty good, in terms of quality.

Aloha··on iPhone 16 Pro and iPhone 16 Pro Max
You and I both want the phonepliance, I work in tech on highly complex distributed systems, and I use an iPhone because its an appliance, it works, I dont need or want to hack my phone, I just want a phone that works.

I just bought my first iPad, going on a work trip next week, gonna give it a whirl, and try that out.

Aloha··on The Beginnings of FM Radio Broadcasting (2018)
You guys did manage to get UHF CB, which we dont have a direct analog of in the states, GMRS is close, but not licensed by rule, you have to pay for and obtain a license, so its not all screwed up. ;-)
Aloha··on IBM 305 RAMAC and the 1960 Winter Olympics
The thing you'll see if you read the oral history, was they could have made it bigger, but 5MB was so much storage then, they were unsure how to sell a bigger one.
Aloha··on I was asked to leave an event for female founders because I had my baby with me
I'm not suited for raising children as a primary parent, but I'm happy to be part of that village raising kids.
Aloha··on I was asked to leave an event for female founders because I had my baby with me
> Really bad look for YC, being a mother is literally the highest calling a woman can have. A blessing and privilege only afforded to women, and they tossed this founder out for no reason.

This is some sexist godddam bullshit.

Yes, motherhood is important - for all of us, and people raising families are something we need to do better to accommodate society wide, but implying the most important thing a woman could ever do is be a baby factory is stupid regressive thinking.

Which makes a more meaningful impact to society and the world, raising one child or saving every human on the planet two hours of labor a week?

Ideally, no one should have to chose, you ought to be able to do both of those things at once, and not having to pick.

Aloha··on What would happen if North Korea launched a nuclear weapon at the US
I agree.

I accept the (United States) need for nuclear weapons until no one else has any - but I'd be the first to sign up for not having them.

Aloha··on CEOs are running companies from afar even as workers return to office
I had the idea for a bookstore/pizza place/laundromat/bar years ago.
Aloha··on How we communicate signals seniority
In the end, without successful business outcomes, there would be no money to pay the paychecks we all need.

Its great if you're a technical person who has a clear vision for your product, if its not a product anyone else needs however, its not gonna do much good for you.
