Analog satellite still uses FM, but there is very little of that left. 30MHz
wide channels. Think there used to be one version of SECAM (in France, IIRC)
that used FM video. That's gone now, too.

Actually SECAM also uses AM for the luminance signal. However, it uses
FM for the color [chroma] signal.

The only FM on standard TV is the audio. Video is vestigial sideband AM.

I want it to be the opposite.

No doubt waiting for the Navasites from the Shirley Maclean alternative

Hint: Extended GSM is a tower feature, not a handset feature.

False.

1.9 GHz is in the -region- of 3 GHz.

False.

I want you to go away until you at least have a high school education
in science and techology and learn how to use Google.

I don't think either is going to happen.

False.

It certainly is within about 20%.

No radio engineer would agree.

Probably not, but that's Usenet. ;)

That should have been about 30%, but in any case, I am an engineer
and there isn't a whole hell of a lot of anything different between
1.9 GHz and 3 GHz.

What? Some trivial differences in path losses? Antennas a bit different
in size by what, 4 mm unless I slipped a decimal point in my head?
