That was needlessly snide and nit picky.

Re: [Elecraft] KX3 manual page 14 regardincg "TUNE".
Please disregard my post as I have "re-found" the answer. Long story short...I started this activity some six months ago and had to stop for personal reasons. I had simply forgotten that Ray K2ULR had provided the answer back then. When I realized it, I tried to stop my post but Keith WE6R emailed me that there is no way to do that.

Kent, You're technically correct, but for the 67 years I've been a ham, "CW" has meant Morse code on the ham bands. This has, indeed, led to misunderstandings about the bandwidth of Morse transmission. A constant carrier has near zero bandwidth. Morse transmission occupies hundreds of Hz in a GOOD transmitter. And Morse operation on the ham bands is 100% amplitude modulation of a carrier by a train of rectangular waves, which in poorly designed rigs produces intermodulation distortion in the RF signal chain, sidebands that are heard as key clicks. In general, the strength of sidebands is proportional to the speed of the transitions from on to off and off to on -- the faster the transition, the stronger the clicks. One of the many virtues of Elecraft rigs beginning with the original K3 is that these transitions are carefully shaped to minimize clicks while maximizing readability. 73, Jim K9YC __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] KX3 manual page 14 regardincg "TUNE".
Let's get our nomenclature right ... CW never means Morse Code. It means continuous wave or carrier wave (used interchangeably). Morse-type Code occurs only when a continuous wave is turned on and off to represent letters, numbers, and punctuation according to a given language's agreed upon chart of correlation. CW is a mode of transmission. Morse Code is an application using that mode. 73, Kent K9ZTV > On Feb 6, 2023, at 10:15 AM, an Amateur Extra wrote: > > Normally, "CW" means morse-code. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

It's not really an unmodulated "FM" signal; it's an unmodulated carrier. There's no reason to assign an arbitrary modulation designation -- why not say it's an unmodulated FSK or PSK signal? --- Mike N4CF __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

You are correct, it puts out a plain carrier, CW with the key held down. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Feb 4, 2023, at 10:46 AM, JEROME SODUS wrote: > > Hello, > > My question is about the "TUNE" selection (half second hold of the XMIT > button). > > The manual's wording is > "TUNE is used to put out a CW signal at the power level selected by the __ > PWR control.". > > Normally, "CW" means morse-code. > But, in this instance, am I correct in thinking it stands for "continuous > wave" or, in other words, an unmodulated FM signal (constant carrier and > amplitude)? > > The reason for my email is > I am setting up a Magnetic-Loop-Antenna that has a "remote tuning" capability > and that "remote tuning" set-up is not going very well for me. > If the KX3 is putting out a continuous wave, then there is a serious problem > with the "remote tuning" box. > > TIA for any reply. > 73 jerry km3k > KX3 #6088 > __ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to wun...@wunderwood.org __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

CW = continuous wave, an unmodulated carrier CW <> Morse code, although many take it to mean that these days. One doesn't "learn CW", one "learns Morse code". Do you have a watt meter between the KX3 and the loop? 73 de Lee, AA4GA On Mon, Feb 6, 2023 at 11:14 AM JEROME SODUS wrote: > Hello, > > My question is about the "TUNE" selection (half second hold of the XMIT > button). > > The manual's wording is > "TUNE is used to put out a CW signal at the power level selected by the __ > PWR control.". > > Normally, "CW" means morse-code. > But, in this instance, am I correct in thinking it stands for "continuous > wave" or, in other words, an unmodulated FM signal (constant carrier and > amplitude)? > > The reason for my email is > I am setting up a Magnetic-Loop-Antenna that has a "remote tuning" > capability and that "remote tuning" set-up is not going very well for me. > If the KX3 is putting out a continuous wave, then there is a serious > problem with the "remote tuning" box. > > TIA for any reply. > 73 jerry km3k > KX3 #6088 > __ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to lee.hi...@gmail.com > __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
