[K3] SSB no output

Hi all,
Here is the problem. I am using my K3 in SSB mode. I key down the mic, and
it shows the red LED "TX" quite bright, but no power is coming out.
However, when I key the radio with the audio input from the computer (using
N3FJP's AC Log software) I am able to play a recorded file (e.g., "W4PAH",
"Thank you, you are 59 into Wisconsin", etc.).

I've tried both my hand mic and my desk mic. No difference in behavior.

I haven't changed any settings that I can recall. Help!

Re: [K3] SSB no output

Double check the Mic setting (front panel knob). If you accidentally
turned it to zero you'll get no output. Don't ask me how I know.

John,

Specifics on the microphones involved may be helpful as well as your mic
gain settings.
Some microphones are Electret type and need bias turned on in the menu,
others are dynamic and do not like bias (they might work, but can 'sound
funny'). The Elecraft mics all use electret elements and need bias
turned on.

In other words, more information is required for a good answer rather
than guesses.
You can (and should) do testing in TX TEST and obtain enough audio to
drive the ALC meter to 5 to 7 bars with compression set to zero. Once
you have obtained that level, increase the compression to whatever you
desire.

If those conditions are all OK, you should have SSB output.

73,
Don W3FPR

Wow! Thanks for all the positive and helpful comments. I feel like a
fool...somehow I had MIC GAIN down to 0. I am clearly the most talented guy
on this list! ;-)

Ha.

Nope, there are lots of us 'talented' types around here. Welcome to
the club. I remember learning that the VOX was important when running
CW on the K3. I never would have guessed.
