Jim,
Are you setting your audio correctly to produce 4 bars with the 5th bar flickering on the ALC meter? If not, you will not transmit properly. See the article on my website www.w3fpr.com. Scroll down in the left column to the last article and click the link. Ignore the recommendations on the internet and many data mode applications to set the power to max and adjust the power with the audio level - it just does not work that way with Elecraft transceivers. 73, Don W3FPR On 2/18/2018 5:00 PM, James Bobo wrote: > Just trying to get on FT8 with K3.

I am assuming you are running WSJT-X.
I don't think you can use the same COM port for the CAT Control and PTT Method. If you don't want to use a separate COM port for PTT then you should be able to get it to work by selecting CAT instead of DTR.

Mike,
The same COM port can be used for both control and PTT. You must set the K3 KEY-PTT menu to the correct setting (depends on the PTT setting you have chosen in your software application. If the red TX indicator does not turn on, you have not set it correctly. OTOH, using PTT via CAT command works reliably (with PTT-KEY set to OFF-OFF), and I recommend that. Alternately, VOX works reliably in DATA modes, so that is a good second alternative. If the TX LED turns on, the K3/K3S/KX3/KX2 is in transmit mode (so no problem with that), but if you do not get proper transmit, check the audio levels as I indicated in the last 2 emails I have sent on this subject. Two different problems - 1) failure to turn on transmit (PTT problem) and 2) Insufficient (or excessive) audio from the soundcard. Each one has its separate indicators. 73, Don W3FPR On 2/18/2018 7:14 PM, Michael Eberle wrote: > I am assuming you are running WSJT-X. > > I don't think you can use the same COM port for the CAT Control and PTT > Method.
