I'm a bit puzzled by this, especially the selection of mic source. Do you have to go through all this whenever you change from SSB to data mode? Doesn't the K3 have independent settings for data mode so once it's set up you just select data and it's all ready to go? -- Julian, G4ILO K2 s/n: 392 K3 s/n: ???

Re: [Elecraft] K3 PSK issue - How to?
I was using UpperSB. I tried the DATA A mode with the same results. I didn't like the very narrow bandwidth the DATA mode uses. I am a little confused by the DATA mode selections. I don't want to send PSK via CW paddles or by FSK. I am just trying to go to/through the computer soundcard.

Re: [Elecraft] K3 PSK issue - How to?
I am having a little trouble with PSK. big snip Did you put the K3 in Data A mode? You should be running mic gain so that ALC barely registers, or below. Zero is Good. Set the power however you want. I included a previous summary of settings I've uesd that might help out with this. matt - WA6EGJ K3 s/n 24 == stapled-on == Data MD: Data A TX line in setting: 20% of full scale.
