I grew up on a vineyard. Each harvest time the grapes would hang down heavily and almost touch the ground. Our pet dogs would park themselves beneath and greedily consume a whole bunch.

They would also scoff any dried grapes they found on the ground.

The worst effect seemed that they all would get noticeably pudgy during the season.

However "Longwave and Mediumwave Broadcast" unambiguously refers to that service.

Once-off Broadcast Transmitters need only demonstrate that they meet the relevant standards.

Many of the existing LF and MF BC transmitters were effectively custom built to meet the requirements of their transmit license (for example, the radiation pattern of the antenna were often unique for each station).

Many good AM receivers do exactly the same thing, especially those receivers which have "Synchronous Detectors" for AM.

It's just that the circuitry involved is simple for FM, but rather more complex for AM.

As the OP has said, it cannot give louder bass, but simulates the bass harmonics.

The "Woolyness" of AM broadcast (at least in America) is due to the stations purposefully tailoring their audio processing to suit typical cheap AM receivers. And this in turn is because designers of cheap AM receivers fit narrow filters instead of using noise reduction techniques, eg a good outside antenna.

There was a period (in the rest of the world) where high quality AM receivers had a narrow/wide switch to give better audio response to stronger signals.

The good news is that modern SDR receivers usually have selectable bandwidth on AM so as to derive the full transmitted audio. And many of these have AM stereo decoders as well.

If you listen to a good quality AM broadcast (eg Gov AM stations in Australia) you will hear audio which are very hard to tell from FM audio.

Go back and read the many high-quality AM tuner articles in the electronic hobby magazines from the past.

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

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".

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.

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

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).

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.

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.
