Huh? / Re: Peter Tork, Court Jester of the Monkees, Is Dead at 77

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.

Do a web search for 'meth in north korea'.

The RF Workbench / Re: Beginner class D design
« on: February 26, 2019, 0441 UTC »
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?

Huh? / Re: What Happened To Radio AND “Liberal Talk” Radio?

Last time I tuned in the area npr station I thought it was mostly classical, some jazz and some soft news. So I had to check.

Huh? / Peter Tork of the Monkees dead at 77
« on: February 21, 2019, 2001 UTC »
It's a Fox News story, at least none of the comments about it blame Hillary or Obama, so far...

Nice! Only one problem: "Does not ship to United States"    :'(

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.
