I'm a big fan of Tapestry too. It's deep, but not "I'm gonna cry uncontrollable tears" or "I'm gonna be uncontrollably angry" deep. It's just ... deep.

Q: Why did you cut snap and health care research?

NEW: Minnesota just ranked the third best state to have a baby. That’s no coincidence.

We’re expanding paid leave and child care, delivering a nation-leading child tax credit, and investing in public schools. We’re putting families first and it’s making a difference.

Elizabeth Warren on Why Billionaires Are Doing All They Can to Stop Zohran Mamdani Elizabeth Warren explains why billionaires are boosting Eric Adams and Andrew Cuomo to keep Zohran Mamdani from becoming New York City's mayor.

At @rollingstone.com, @elizabeth-warren.bsky.social lays out the stakes of our election.

"It turns out there are some billionaires and Wall Street CEOs who can’t stand the idea of a mayor who wants them to pay their fair share to create a city that everyone can afford."

If you buy a home, learn from my mistakes and keep a list of:

* the manufacturer and model of all of your faucets / fixtures
* every paint color + manufacturer + glossiness of every paint you do

Next up is cracking open this TS-430S and checking for the usual suspects (dry joints again, loose cables again, loose crimped connectors again) and make sure it's A-OK on both transmit and receive.

I'd like to at least know I can do 10W of 220MHz AM, FM and sideband with decent audio.

Gnight!

I plugged it in today and hit the KU6V 1.25m repeater just fine. However, I have in the past had issues where my little tone board hack would engage the repeater itself fine but wasn't strong enough to engage the REST of the repeaters in the network.

Also, sideband TX power seems low. So.

It puts out ~ 10W, and I put it in a box a few years ago with a little control PCB and ALC detector to detect SWR/power issues.

I should open it up again and finish designing some clean PCBs to control it.

Anyway.

So, the TS-430S has a transverter output jack which helpfully gives you all the TX/RX/PTT signals you need, and disables the on-board amplifier so you just use the transverter.

And I'm using one of those ukranian transverters from transverters-store (which has since shut down, cry.)

Anyway.

Ok, so the TS-670 QRP setup is working fine, and although 10W isn't a lot of power on 6W, it's a "adrian wants to build a collection of period radios" correct for the setup.

I'll have to go find or make a 100W 50MHz amplifier.

Anyway, next up - the TS-430S 220MHz transverter setup.

A fun reminder that a loss of 60,000 jobs in and around academia is ~50% more than all coal mining jobs in the entire country.

A friend’s kid dabbled in steroid use. It gave him breasts. Instead of having to suffer the consequences of his mistake he was able to have breasts removed. This is gender affirming care. Good thing he’s a cis male or it would be denied. Trans people lose rights - we all lose rights.

PSA for Millennials: new advice is that HRT can begin in early perimenopause. I had my first big hot flash when I was 39 - I'll be 48 in a week.

Talk to your doctor. We want you to have the information that we didn't get (and our mothers/grandmothers didn't have).

How about eliminating cruelty and instead of limiteding it?

Also, ICE needs to be abolished entirely.

And THIS! the lack of money means we don’t foster the smart talented people. We lay them off *every cycle*, AFTER we airdrop them into communities. We cancel White House job offers to dozens of people because they smoked weed in a legal state.

Stars burn out and go take β€œsteady” (corporate) jobs.
