The Win4K3 suite cannot remote the K3/0 Mini. Its documentation suggests that it can, but the author told me he never completed this project. I have had both Win4K3 and remoterig-K3/0 Mini solutions w

Thanks Alex. My question - with split set to "Fake it", is the radio actually shifting down 1 KHZ during TX. If yes, that is a problem. Here is what Bob N6TV told me: Bob N6TV nailed it. WSJT-X Settin

Jim if one of the options marked red FT8 are on, this behavior is normal for Fox/hound mode

Jim It sounds as if all is well with your setup. When I transmit on FT8 the transmit frequency moves depending upon where I put the red cursor in the passband. It moves in 500Hz increments. On 80 my X

Jim, If you have 'Fake It' on (and you SHOULD); if the tones selected are not between 1500-2000 Hz, the radio will shift the VFO frequency so that the third harmonic of the audio will not be transmitt

Strange behavior. FT8 on 80M 3547 rx and 1000hz tx. When I key radio the K3s shifts from 3547 to 3546 down 1Khz. I expected TX to remain on 3547 with tx Up 1000 Hz. First time on 80 FT8 Jim K7EG

I've read through everything I can find and I think I've just confused myself. I recently acquired a K3S and even more recently acquired a K3/0-Mini. My plan is to use the K3/0-Mini in my house to con

While that shows the keyed waveform, it does not show the sideband noise either side of the frequency, nor the transmitter ALC overshoot. Both of which contribute to noise and artifacts either side of

Hi Lou, The K2 uses RC exponential keying envelope shaping, typical of earlier analog superhets. The K3/K3S and all of our current transceivers use sigmoidal shaping in DSP, with coefficients hand-tun

True, it's easier and more relevant to see it the freq domain, but they are factually equivalent via the Fourier transform. Being aware and looking in the time domain is better than not looking at all

Perhaps it is Yaesu's way of cleaning up their bandwidth mess, if you can't control the rig, you are not transmitting, and hence your bandwidth is reduced... 73, and thanks, Dave (NK7Z) https://www.nk

Unfortunately, Yaesu's firmware update screwed up their CAT protocol (they no longer respond to the "Get Mode" poll) which has broken many logging, contest and digital software packages. Yaesu, of all

So THAT's what's making all those super wide signals I see on the display. Wow, you're right, at least 7 kHz wide, almost filling a ±5kHz display. 73, Charlie k3ICH

Time domain is the wrong way to study CW keying. Frequency domain with narrow frequency bandwidth very narrow frequency resolution (better than 2 Hz) provides the best view, by far. See my data, done

True enough. I did the W8JI clix mod on my FT1000MP MkV ~20 years ago and it made a big improvement. And Yeasu just improved the keying waveform on the FTDX101 with a new software release two days ago

Yaesu has long been well-known to be very dirty (clicky) on CW, which is 100% amplitude modulation of a carrier by a rectangular keying signal, which also intermod, which is heard as clicks. Even wors

Thanks to those who did send me a message, but I am still looking for a 100w K3 or K3S with ATU to finalise my shack line-up. Condition is irrelevant (a few scratches are fully in order) so long as it

Yes, that helps but Rob has told me we need 50v designs. Even operators with yaesu equipment that have class A option do not use it. Oh well. 73 Mike R 7! Absolutely Awesome

Yes and it is known that most radios can be operated at higher voltages, Vcc, and have slightly improved results. For that reason, I have the power supply for my K3S set to 14.8 volts, with only 0.4 v

Yeah, k3 is not the greatest either. Rob Sherrwood says the biggest problem is 13.8 volts limitations and guys running knobs all the way to the right. Of course some people can take a perfectly good s
