By chance is TX Gate turned on and there is background noise?

The mics work. My problem was a burst of noise when the rig went into
transmit.
It appears re-seating the USB cable in the back of the radio has cured
the problem. It did not appear to be lose. And the noise would appear
even if I was using the VOX or PTT switch or the internal DVR. In
By chance is MIC + LIN set to the ON mode in the MENU? Should be OFF
for just microphone usage.
I agree with Don. Disconnect everything except the power cables,
antenna coax and microphone.

Buck,
It sounds like that noise is coming from whatever computer software
application you are using. You mentioned N1MM.
When you unplug the USB cable, whatever software you are using loses
communications with the radio.
When you plug it back in, that program is not attempting to re-establish
That could be. USB and computer connections are notorious for causing problems
if they are not shielded or connected properly. By unplugging and replugging
the USB cable you just may have seated it properly and fixed things. Play with
the radio for a while, on the air, and let us know if it
Buck,
I would suggest that you not worry about the noise burst until you can
get a good response out of the mic.
If you do not have a computer mic handy, borrow one and plug it into the
rear panel mic jack. See if you can obtain a response on the ALC meter
with that microphone. All computer
I've tried all the combination of mics and mic bias. The noise happens
even with the mic gain turned all the way down and the rig in TEST mode.
It happens when N1MM is not running. It happens using the internal
DVR card. It happens with the mic disconnected and using the XMIT
button on the
I’ve had CM500 (bias) plunged into rear mic jack and various Heil dynamic mics
(no bias) plunged into front panel ever since I’ve owned my K3 and K3S with no
issue.
This guy has some other issue.

I've kept my MH2 plugged into the front panel and the CM500
plugged into the back for years, and used the MIC SEL to switch
between them. It has always worked well.
Note that both mics require bias. Heil sells both electret and
dynamic elements, so refer to the documentation, or web site, or
Buck,
The Heil Goldline mic is a dynamic type, last I heard it has an HC-5
element. It should have bias off.
The Elecraft MH4 is an electret type and must have bias set on - use
"FP.L bias"
It may just be that you have too much mic gain - start with a mid-range
setting. The mic preamp can
Not sure about the Heil, but the MH4 requires Bias to be ON.

Thanks. I was using a Heil Goldline and also tried an Elecraft MH4
plugged in the front. I get the same noise on FP.L and FP.H Bias is
off. And, I still get the noise even when in TEST mode, so there is no
RF.
I had the Tx Dly on the K3S set to 8. I set it to 15 and the problem
went
Is this a dynamic mike with the bias turned on? If so, turn the bias
off. I trust this is a mike connected to the MIC input on the front of
the radio. If you are using the front mike input and something is
connected to the rear MIC input, unplug what ever is connected to the
rear input.
Buck,
Which transceiver and which microphone?
If the K3, are you using the front panel mic jack or the jack in the back?
How do you have MIC SEL set?

I never use a microphone so here I am today trying to run voice in the
Va QSO party.
When I key the mic, I get a burst of noise that lasts maybe a half
second. It does this even if I have the rig in "test" mode ie. no
transmit. So, I don't think it is RF.
I have tried adjusting the mic
