Ladies and Gentlemen,

I think we have probably beaten several types of Cycles to the point where it now Hertz.

How about we move along and let this one go away.

Kilocycle... Is that anything like a Peloton? The last time I used one of those contraptions, I thought I was gonna die!

actually the energy is still there. never destroyed,just absorbed into something else.
remember we cant destroy energy,but can tap into it.Its reused just like the water. same water that fell when Jesus was alive is still with us Today.

william franklin,

if we did that, we would theoretically become infinite mass, we would go to ludicrus speed :)
Einstein and his e-mc2 and niles borg and his quark theories were great , but now we have SPACE BALLS. going at ludicrus speed and then going PLAID!!!!:)

Just think, if you could travel faster than the speed of light you could travel out into space ahead of your radio wave, slow down, and then copy your own transmission as it went past you.  Wow!!  All this geniusing makes my brain hurt.

Some claim that radio waves never go away, they just decrease in amplitude. Does that mean that there are cycles and hertz mixing? Oh dear, perish the thought!

The phrase "cycles per second" carries a lot of information.  The word "Hertz" carries nothing.

I'm all for the memorialization of the dead.  Three generations of my family have dedicated themselves to just that field of service.  Honoring our electronic pioneers is extremely worthwhile in educating all of us and (in my opinion) has always been done best when chronicled in history books, on geographical plaques, by special events, through temporary signage on Hamvention buildings, and other creative ways.

But not in scientific nomenclature.  Not in electronic vocabulary.  And not when indicating frequencies on the air.

Jerry ,
i was once wet behind the ears also.
lots of Rf and UNix programming in the Day.

Sometime u have to think out of the theoretical black box to have fun and create. I  remember my computer was a slide rule.No ram,No rom, No floppy disks,just a Picket slide Rule and pencil and paper.Actually if you really think about it, communications was being completed long before the transistor was created.:)

ke9uw,

I agree, but im an old rebel. like our roundabouts where everyone slows to a stop when they are just supposed to merge .

Kc also reminds me of the corn flakes i ate before school.Kelloggs corn flakes.

j.k.wright,
we could use acres since some of us are down to earth people.HI HI.OOHHHH that one Hertz!!!!Bad joke i know.:)
as for the navy sounding wavelength, we could use leagues or fathoms? sounds cool. im runnin a 1/4 fathom vertical with 1/2 league radials,.uuggghhh

Now with all this talk about hertz which meshes with maxwell and his magnetism theories,maxwell was the first to theorize the radiation of electromagnetic radiation, so i honor maxwell first, then hertz.Even though Hertz actually did the experiments to the theory. Since we are talking basic science theory here,

who can guess the Godfather of wireless telephone?
1.Marconi
2.tesla
3.Nathen Stubblefield
4.Edison
5. Armstrong
6.Reginald A. Fessenden

On 23 December 1900, the Canadian inventor became the first person to send audio (wireless telephony) by means of electromagnetic waves, successfully transmitting over a distance of about a mile (1.6 kilometers), and six years later on Christmas Eve 1906 he became the first person to make a public wireless broadcast.
I deleted the name so you all have to hertz your brains to figure it out.

maybe 4sqrp could make a bundle kit with receiver,transmitter,etc and name them after our forefathers of radio?

The winner of this quiz will win all bragging rights for at least until someone else posts a question

Me thinks you besmirch engineers - our whole hobby is based on things created by what were referred to as "wet behind the ears" engineers and scientists, at the time.  One of the challenges to "we old timers" (been licensed 59 yrs) is to respect the need for progress, uniformity and occasional change.   I guess we would be happiest if sdr, dsp, and those darn transistors had never been created.  Smile...it's just a hobby, with 100 sub-hobbies in one.
 That is the fun in it. Even I was a "wet behind the ears" engineer at one time!

Actually KC/S is just as metric as KHz.


Re: Question About Class E Transmitters

nm0s_qrp
 

There have been very few articles about tubes in switching applications.  The challenge with using a tube is that when the tube conducts large cathode current at low plate voltage, the grid and screen currents may become large enough to cause damage if not controlled.  Otherwise, there is no need to parallel devices, just use a pi network  to perform an impedance transformation.

when you look at a scope you are looking at the cycles of the waveform displayed
So cycles is appropriate to me. Hertz is an adopted term which makes me think of the rental cars.
7039.5kc   vs 7.039.5 mhz.

Look at the old crystals and alot i have in stock says Kc on the body.
Just me being biased,but i enjoy the old ways of Kc
