K3 Inquiry

[Bob Lightner]

My High School club station, K4WTL, uses a K3 for CW. It works great!
Recently we tried to transmit on SSB. The radio doesn't seem to want to
transmit audio. The Elecraft hand mic is plugged into the front and the
menu confirms that. The Mode is correct and the firmware is up-to-date. We
have substituted microphones and nothing seems to solve the problem. Have
any of you had similar problems??? Bob/W4GJ, trustee for K4WTL.

Bob,

Is the MIC SEL set to "FP.L bias"?
If bias is not applied, there will be no audio from that mic - it uses
an electret type element.
The default is bias OFF - because the bias could harm dynamic type
microphones.

Most likely problem is: the Elecraft mic (MH2 or MH4) is an electret mic and requires that a bias voltage be present on the audio pin.  The MicSel should read “fPL bias”. If “bias” is not shown, press the “2” button on the panel to right if display to toggle the bias.

If MicSel shows fPH, press the “1” button to toggle H/L.
