[Elecraft] K3 no RF on FT8

[Julia Tuttle]

Just spitballing what I'd check:

Have you checked all the computer-side settings? There's output attenuation
in the app, per-app output volume (on some operating systems), and master
output volume.

If it can be toggled or there are separate jacks, are you using headphones
or line-out? Have you tried the other?

If you've got an audio interface with a hardware output gain knob, have you
checked the settings on that?

Have you checked the cables and connections, and perhaps tried another
cable?

If you're using SSB instead of DATA mode, have you checked the COMP and TX
EQ settings? (DATA mode avoids this problem.)

Have you tried transmitting some other computer audio, like a plain sine
wave of good volume? This would isolate the app, output attentuation, or
per-app volume.

Have you tried transmitting some plain mic audio in the same mode? This
would isolate the app, computer, or interface.

73,

Julie
