K3 Tx audio coming through speaker

Hi all,

After working perfectly for awhile my K3 has developed the following problem, when I key the mike and transmit in SSB mode the audo is coming through the speaker while i’m transmitting, I have not got monitor turned on and this happens wether using the internal speaker or headphones.

I’m hoping this is just caused by me altering a parameter in the menu’s that I shouldn’t have done.

Thank you in advance for your help

Regards
Graham G7NEH

Re: K3 Tx audio coming through speaker

Are you sure it is coming from the K3 speaker and not from speakers on a
computer that is connected to the K3 line out output?

Hi,
Yes, definitely coming from the K3 I have not got anything connected at all apart from the antenna.

Graham,

Turn on TX TEST mode and see if that condition is still present.
If it is, double check the MON setting to be certain you did not
inadvertently change it while trying to adjust the power level or
compression.

If it is gone with TX TEST, next try it while transmitting into a dummy
load.
If it is still gone with the dummy load, I would suggest you look to see
what has changed in your antenna system because at that point I would
suspect some type of RF feedback.

> Yes, definitely coming from the K3

You say audio...but is it really audio, as in demodulated sideband? Or, is it
undemodulated single sideband you are hearing? Big difference. If
undemodulated, then it is likely a change in your grounding or something else
that has affected the RF levels showing up in your mic or line inputs, or even
your speaker system.

Hi,

Many thanks to Don, Jim and others who took the time to answer my post, it was the MON setting that was causing the issue I must have inadvertently changed it as Don said below, now all working fine again. I’m glad it was only finger trouble.

Once again many thanks for the help it was very much appreciated.
