"Says who?  ::)"

Says someone who can't find it on FM anymore! The best that's out there is 15 min. of tunes you heard thousands and thousands of times then 15 min. of commercials.
But now we have bittorrent and youtube-dl so we can rebuild our long lost vinyl collections.

The whole reason for using shortwave is to use skywave propagation and to broadcast rock music mostly from the late 60's to early 70's.

Even Pigmeat is sounding paranoid these days! What gives?!?!?

I looked again for that variable attenuator circuit but can't find it. It is just a 200 ohm pot and a 51 ohm resistor. The input is the wiper of the pot. The resistor goes from one end of the pot to ground. The other end of the pot is output. More at Wikipedia:

Seriously dude? Half a watt? Nobody is gonna hear you!

Edit

That was rude of me. You could use a variable power supply and run it at less than 12 volts. You could make a Variable RF attenuator from a potentiometer and a resistor.
There is a name for the circuit but I can't remember or find it now. I would look at the Chinese Pixie kit on ebay. For about $4 you get a nice PCB and a bunch of parts and there is alot of info on youtube.

I think somebody put a FM pirate TX up there (9000 ft.) and they were trying to find out who did it.

We lost internet the last 2 nights around 8:45 PM ET. I was listening to WBCQ Saturday night and they lost the feed from the Lumpy Gravy show. But later RFE played side 2 of Humble Pie Smokin.

Earlier tonight there was about a dozen very strong wefax stations on at the same time around 6.3-6.5 Mhz.

The good thing about the technology today is that the hardware, Arduino, Raspberry pi, Orange pi, ESP8266 is very cheap and the software and documentation is free and easy to find on the web. I remember when it cost hundreds of dollars for a book and a C compiler.
One thing I don't like is that most Arduino tutorials start out by showing how to blink a LED. Why use a microcontroller to do something you can do with a 555 timer I.C..
You already have what you need to do it from the keyboard of your computer using 'serial begin (9600).

'You know who' hates science, the post office, unions and dumb southerners. He took $10M from FEMA and gave it to ICE. He needs the space to build more baby jails.
