Hmm. Maybe my transceiver is just nice, but i have no reception issues when I'm 5kHz up or down - I obviously don't know how I sound, but I've had conversations before. I guess they just assumed I had a weak signal.

Now THAT is interesting!

Sorry, I'm used to VHF/UHF voice operation on 2-meter - a .004 difference isn't all that bad and would still be entirely functional - the service/band that I'm talking about is not channelized.

More context: so the plane would be going, perhaps, 1000km/h (or 0.277km/s). Orbital velocity for LEO is 7.8 to 6.9 km/s.

In short, that was what I would call a stupid question.

LEO is a lot faster than the crusing speed of a 757. The doppler shift involved is almost completely negligible.

Assuming the plane is moving directly away from you (maximal doppler shift) at 858km/h (typical cruise speed), with a wave speed of 'c' - you have a doppler shift of +/- 3.974975 kHz.

I'm pretty sure radios capable of transmission are still a no-no.

I'm pretty sure they have all known about this for some time. This isn't a new thing.

Clapper and Alexander have those new fancy "truth inverters" installed. When they deny something, it's true. When they admit something, it's not true - and if they refuse comment... hide.

Wait! Can we have them play in traffic first?

... and I hope that "string of profanity" was directed at the NSA who put it there.

Wrong. Around here, it's either 45, 50, 55, 60, 65, or 70 - depending on what county you happen to be in at the moment.

Oh not to mention those random spots where it drops from say 65 to 45 and back (or down to 35!!!) for no conceivable reason. Better not miss that (one) sign!

2 seconds!? Do you have a disease or disability? I can sit with a stopwatch (yes, so I'm already multitasking with that) and I can get useful information while only having my eyes diverted for1/2 of a second typically - sometimes shorter if I only need to catch the shape of something (eg the turn direction indicator)

It's more dangerous to reach over and adjust the stereo volume!

Also, at 70mph, you better not be anywhere near houses. 50 feet (1/2 second) is peanuts compared to stopping or maneuvering distance. If something happens close enough that that matters, you're going to roll your car avoiding it or hit it anyway while (ineffectually) stopping.

Indeed. My speedometer has matched every roadside radar display I've encountered.

If they wanted to do such things it would be far easier for them to plant trackers surreptitiously - not fired noisily while tailgating the target.

I have seen high speed chases where the driver was executing maneuvers in such a way... he/she clearly was not only in charge of all their faculties, but calm.

Seriously - we're talking about multiple spin recoveries (after PIT maneuver attempts) in a row. Car started to spin, they spun into it and completely around and kept on going - didn't even veer off course.

Eventually it was a mechanical failure that stopped the chase - one of the tires finally had enough and blew.
