Airsoft?! Huh?

So long as it's a true Montessori and not just in name only. The number of programs I see touting Montessori, Classical, and other models is wild. Usually it's charter and private schools that say one thing but do another.

Also no one is talking about how exposed we are to Taiwan. Nvidia, AMD, Apple, any company building out GPUs (so Google, Microsoft, Meta etc), even Intel a bit, are all manufacturing everything with one company, and it's largely happening in Taiwan.

If China invades Taiwan, why wouldn't TSMC, Nvidia and AMD stock prices go to zero?

We aren't? It's one of the reasons the CHIPS Act et al get pushed through, to try to mitigate those risks. COVID showed how fragile supply chains are to shocks to the status quo and has forced a rethink. Check out the book 'World On The Brink' for more on that geopolitical situation.

You can work the ISS fairly easily from your backyard with an Elk or Arrow antenna and full duplex radio like D72A. I have worked astronauts. During COVID, we all used to get on the satellites as part of late night passes at like 1am and make contacts with each other.

You don't even need full duplex. Just an HT that will do "split".

As someone who only has a 5w transmitter, I avoid field day and major contests. I love doing Parks on the Air when camping, and that ends up being a lot more enjoyable.

This is the way.

QRP for FD is like going fishing without a hook. You better enjoy the scenery and getting away from home because you're not going to bring in much.

Different people find "fun" in different things. Field Day is fun for the planning, deployment, and operation of ham stations in the field. Some community outreach, some teamwork, some emergency preparedness, and some good practice.

I agree that actually operating during field day is less fun than at any other time of the year, unless you're in "competitive mode" and are trying to win the most contacts in your class. During these three days, the conversations are very short and mostly all the same, so there's not much "rag chewing" going on.

Field Day can also be fun in the sense that you may get permission to do things that you ordinarily could not do, such as operate a station in a public park, and camp there with it for two nights. Another "fun" element is improvising with what you have, such as setting up a station on the top floor of a parking structure in a metropolitan area.

All things that can be done at any other point during the year and you have the added benefit of being able to hear other stations.

This is a great time to be on the air especially if you're into late nights and enjoy setting up an outdoor station. Want to work all states? This is a good contest for it. It's my 2d favorite with the November CW Sweepstakes coming in first place.

Actually it's not. It's just wall to wall QRM. You can't exactly setup on a single frequency and call CQ without some asshat setting up right on frequency. I abhor Field Day because it's chaos. POTA, state QSO parties, 13 Colonies, Museum Ship Weekend, those are my speed.

Most every ham club that sets up for Field Day talk like they're doing "public service" and "outreach", but then they post up at some obscure location quite a way away where most any 'public' would be. The scant visitors they get are either ignored or greeted in an overly excited way and then every old timer wants a chance to impress upon the visitor their view of radio which invariably runs off all but the most determined visitors who can see past all that. I've been to over a dozen different club field day events across the country and most of them are pretty cringy.

---

The best was Tucson almost 20 years ago because my wife and I happened to be tent camping on the same mountain peak where they were setup. She retired to the tent early, I played radio well into the night after the daytime RF pandemonium died down. In the morning one of the club members who also runs a restraunt made everyone omelettes to order on his catering flat top.

One of the worst was Palm Springs RATS. Their setup was at their EOC and closed to the public. I had to essentially "prove" I was a ham to even be allowed in with them. (I told them my callsign but that wasn't enough. "Hi. I'm <callsign> in town for work and thought I'd drop in to do Field Day with you guys." "Do you know anyone here?" "No, I'm just in town for work." "Well, this is a ham radio event." "Yeah, it's Field Day. I'm just here for the week ahead and thought I'd come play radio with you guys." "...and you're not a member?")

Some club in DC/Arlington was pretty awful too. Again, there for work. Two old timers took turns mansplaining ham radio to me most of my time there. Nevermind I was a 30-something dude and with-code Extra. I was on their "get on the air" station doing CW and they kept talking at me while I had headphones on copying callsigns and listening for a break in the pileup.

These days I just don't even both going out because I've been disappointed so many times. Maybe I'll give it a go this evening to yet another new club's setup and see what new form of disappointment awaits.

One bigger hit and its gone and you will not even know it till it fogs. Even argon glass of same pressure as air can eventually leak out and be replaced by air, reducing its efficiency significantly.

Are these big national-brand window companies that provide "lifetime warranty" just cashing in today and hoping for the best (bankruptcy) exit strategy later when all their installs from this generation fail in a couple decades?

Not installers, but companies like Pella, Window World, et al.
