KPA500 Oper/Stby beep

[mike]

I am not finding where to turn off the beep that sounds when changing the KPA500 status from standby to operate (and back). Sometimes it gets very 'buzzy' sounding and a I would like to just turn it off. Anyone else have this happen?

Are you sure this is coming from the KPA500?

The only beep the KPA500 emits is when a hard fault occurs.

I guess I did not describe it well. I am listening to the K3 audio. The K3 is connected to the KPA500 via the Elecraft Auxbus cable. When I hit the Oper/Stby button on the KPA500 to toggle on or off, I hear a tone. Usually it is a clear bell like tone. Sometimes that tone gets very 'buzzy' sounding although I cannot tell you when or how at this point. If the tone comes from the K3, as I most likely does, I want to turn it off. Since it is initiated by the button on the KPA500, I wondered if that was where I would make the change. I have already set the SW Tone to Off on the K3 configuration, but it does not effect the KPA500 Oper/Stby tone.

It might be better to try and find out what causes the 'buzzy' sound, but for now I would be happy just to eliminate the beep's initiation.

Hookay, I figured out what I am responding to. It turns out the 'buzzy' beep only happens when the K3 is in SSB mode (not a mode I use all that often) and Noise Reduction is on. It almost sounds like an overloaded audio circuit, or maybe like the trailing hash that you see/hear in the movies when the police officer un-keys his mic..."that's roger, over.. kesssssh!" Unpleasant to hear, but not more than an annoyance. I still would like to silence the beep when I switch the Oper/Stby button on the KPA500. Is there a way?
