Echo when transmitting

Ideas to correct the following would be appreciated - thank you in advance.
This is something new and I am perplexed.

I am using a Heil Pro-Set Plus microphone/headphones (with elements HC4 &
HC5). The microphone line is connected to rear of K3 in the "Mono" jack.
The Heil headphone 1/8" stereo plug is connected on rear of K3 to "Phones"
jack. The footswitch is connected to rear of K3 "PTT In".

When in VOX the K3 stays in transmit and sounds like echo of shots (my
imaginary sound) - when in PTT (preferred mode), as soon as I press the
footswitch to transmit, K3 TX light turns red, headphones outputs a series
of sound of echoes even before I say anything and if I speak my voice
echoes...

Mic Select FP.L with Bias set to Off

Mic + Lin On

Mic Gain 20

Comp 12

VOX Gain 050

VOX Delay 0.50

AF Gain High

SPKRS 2

SPKR+PH Yes

Is the TX monitor turned on?

Re: Echo when transmitting

That would be my first question too. How about checking your LINE IN
to see that there is no signal on it. If you have it connected to a
sound device, there could be non-MIC input happening, along with your
voice audio. Or you could have your own voice audio coming into the
input from both the MIC and the computer / sound device if the sound
device's monitor audio is enabled.

Re: Echo when transmitting

Hi Tony & fellow Elecrafters,

Could be that you have your monitor level up too high, could this be the
source of your "echo" but there is virtually no latency or delay (Echo)
as with an echo.

My thoughts for what it is worth.

Eric, VK3AX, (K3 4520).

Re: Echo when transmitting

In reply to this post by Tony McClenny

I had a similar problem some time ago. had me baffled for a while

If your computer is connected to line in and out try disconnecting
them. If the problem disappears then check that the sound card used
for the K3 audio by opening recording devices, then select the device
you are using for the K3 and click properties. Under the Listen tab be
sure that the box for "listen to this device" is not selected.

If it is it can create feed back that has some delays from both the K3
(if monitor Normal) and latency withing the sound card itself to create
this kind of echo. drove me nuts trying to figure it out.

also I find I need to keep the monitor level down when using the
headset, Yamaha CM500 here, otherwise there is some audio feedback

Re: Echo when transmitting

Thanks to everyone, who offered a suggestion. David's thought appears to be
the issue.

It seems you have pointed me in the correct direction - thank you.
Disconnected K3 input to computer soundcard and the SSB noise / echo
disappeared - now to fine tune. Thank you.

There was a time, around the time when dirt was young, that the mic had
a 1/4" phone plug on it and went to the 1/4" mic jack on the front panel
of the transmitter, the headphones had a 1/4" phone plug that was
inserted into the 1/4" jack on the receiver, the key had a 1/4" phone
plug plugged into the 1/4" key jack on the front or rear panel of the
transmitter, PTT was STT ["switch to transmit"], a toggle switch usually
on the transmitter, and there was no computer ... they hadn't been
invented yet. OK, the Collins KWM2 and S-line had a 3/16" two circuit
mic jack, Art was always a little ahead of the pack.

My experience has been that, if something is going wrong or is producing
unexpected results, disconnect the computer. Works just about all the time.

Re: Echo when transmitting

In reply to this post by Tony McClenny

Tony, Glad all seems to be OK.

BUT, the first thing I noticed in your settings list it the Microphone
select is FP.L

You said in the previous paragraph that your were plugging the Microphone
into the REAR PANEL.

If that is the case, then you should select RP.L when setting up the menu.
At least that is what I do.

73 and good luck with the whole banana.

Me too, but I'm a bit too late to answer!

Anyway there are other settings that 'sound strange' to me:
>>
>> When in VOX the K3 stays in transmit ....
>>
>> AF Gain High
>>
>>
>> SPKR+PH Yes
>>
The only thing that 'sounds normal' is that, with SPKR ON, at high volume, the VOX do its job and switch to Tx!
Tony, try to set SPKR+PH => no, AF low, and you will stay Rx until you speak.
About the strange sounds... you have already solved the problem!
