Yes, this is one of the proposed methods. It's known as "Independent Sideband".

It works, but it is a fairly expensive method to implement.

There were a number of successful AM stereo broadcasting methods proposed and trialed. These were completely compatible with conventional AM transmissions.

The conceptually simplest of course whas where the LSB and USB are used as separate channels.

Although most of the systems did work, they were not ultimately successful simply because insufficient stereo receivers reached the market.

Go search in Wikipedia on "AM Stereo".

Of the methods listed on Wikipedia only ISB is a true AM. All the others use phase modulation for the difference signal, as an easy way to achieve compatibility with mono AM receivers; and PM is basically the integral of FM.

Wikipedia says that there was basically one station doing ISB stereo; which I guess is close enough to "nobody did it", but not quite "it was never done".

There is no reason that the channel spacing need limit the sideband bandwidth.

The only downside to this is that listeners on adjacent stations hear a slight "monkey chatter" from the overlapping sidebands.

This is one of many reasons why station frequencies are never allocated close to stations which are physically close.

You only need glance at the waterfall display on a good SDR receiver to see that the actual audio bandwidth is often much wider than the channel spacing implies.

The pickle will shunt (steal) some signal, but the radiated power from the antenna will be very much greater than that flowing through the pickle.

Because your nerves don't respond to high frequencies, you cannot "feel" RF current.

What you do feel is the intense burning associated with the RF energy being converted to heat.

You have it backwards:

Fessenden is famous for developing a electomechanical RF generator which put out a clean sinewave (eg a coherent wave), which helped replace the earlier Spark-Gap systems (which generated wide-band hash).

Or even simpler, use a Neon bulb. or even a Fluro light.

Indeed.

But little neons are getting scarce (they aren't dear -- they're just much, much less common than they used to be). And working fluorescents (with magnetic ballasts that actually run at line frequency) are pretty much that way are too.

LEDs and resistors, though? Bright, cheaper than chips, and ready for all kinds of modern digital shenanigans.

The alternative is to do the standard sitting exercises intended to avoid DVT.

eg wiggle your toes, flex your leg muscles, rock your feet, etc.

All you need do is avoid pinch points which block blood flow.

These are routinely taught to solders on point duty, pilots on long flights, patients confined to bed,etc.

There are simple exercises that you can do while seated to avoid DVT. Just wriggling your toes help a lot, or flexing the muscles in your legs.

I fly a lot on routes over the tropics and have experienced serious turbulence multiple times. There's no way I will be wandering around the cabin unnecessarily.
