At least the AD website usually works on weekends. Many of these companies’ websites apparently need constant manual correction to continue operating, with the result that i often find I can’t download datasheets on Sundays. Bad for the hobbyist for sure.

I have trouble with slow page loads and can't order samples from Microchip on weekends.

This is universally the case for hardware companies I’ve found, even suppliers. We get Farnell, CPC and RS outages at the weekend here in the U.K.

Yes. The LT web site was gold. How it should be done.

The Hittite web site had some great tools such as a graphical mixer spur calculator. Of course that is gone. ADI tech support sucks. The HMC6300 documentation is poor and buggy, and tech support won’t help. Used to be you could call Hittite and speak with an engineer. ADI is a black hole of web forms and forum posts.

I just hope they leave LT Spice alone, but I’m sure they will fix it until it’s broken.

For what it's worth, I think the mixer spur tool is still available here (http://playground.analog.com).

See the recent Amp Hour episode for some specific discussion I heard about these tools and their development. (https://theamphour.com/392-an-interview-with-matt-duff/)

LTspice is incidentally broken as fuck on windows 10 1803 so YMMV with that already.

LTSpice runs perfectly under wine, which is a bit less of a treadmill.

Never tried it under wine. Will have a go at that.
