MGM Springfield just announced Aerosmith will do 4 shows in August to celebrate their one year anniversary. $89 to $499 a seat. 3 of the 4 shows are on week nights. Somehow I don't think it will end up being 4 shows.

The RF Workbench / Re: Beginner class D design

Maybe OT but could you modulate a class D amp by controlling the duty cycle of the drive?
Does that exist, if so does it have a name?

It's a Fox News story, at least none of the comments about it blame Hillary or Obama, so far...

Teotwaki, that's the exact MP3 module I was referring to here:
https://www.hfunderground.com/board/index.php/topic,48577.0.html
I ordered the diodes and they arrived a couple days later but I never did anything else.
Str. posted a schematic that looks adaptable. Next step would be to figure out the transformer. Probably a small toroid core?
The audio amp is rated 2 watts so you could use it to modulate a 4 watt transmitter.
