Very Cool - US to South Africa on QRP -VOICE-

[RadioRay]

Here's a YouTube video of a voice contact from USA to South Africa. They eventually drop the power to one Watt. Evidently, the US station has a 200 meter long vee-beam (wire beam) antenna, but still, this is impressive! In Morse it would have been quite 'do-able, because of the virtual 13dB+ system gain of CW over HF radio.

On the other hand, this is an attempt at a 15 mW contact using a speaker cone to generate the electricity to run a small transmitter by ... er, ... well yelling Morse code into a bean can.  You just have to see this.

My ex-wife could probably generate a kiloWatt this way, she could yell so loud and long...

You could hook a generator up to my ex's mouth and power NYC for a month!

And then there's this guy who made a straight key with generators from flashlights in it that power the transmitter with each dit and dah.

My wife brought home an old sewing machine treadle base.  It's been sitting in the garage for 2 years.  The first time I get boored I'm mounting a generator on it.  That way I'll have a desk and power source in one portable unit.  It would be a laugh at Field Day.
