Xmit Audio

Roy Davis
I have had a couple of stations report a gravely or sort of overtone on my K3's xmit audio.  Not everyone reports this, but more than one has.  Has anybody had a similiar experience?  Could it posibly be RF?  This was not noticed with another radio when in line.
 
Thanks for any help.

If you're using compression, try turning it off and see if the audio report improves.

Re: K3 Noise Gate Function

Roy Davis
In reply to this post by Roy Davis
I down loaded the Beta 2.46 version with no glitches.  I haven't noticed so far any problems created by it.
 
However, when using the Noise Gate function, after quieting the back ground noise, in between words I hear a crackling or static sound in the headset.  I haven't spoke with someone yet to know whether it is heard on the air.  I suppose it is not.
 
But it is annoying.  Has anyone else had this to happen, and is there a cure for it? 
 
I think the noise gate feature has been long over due in the radios manufactured.  Thanks Elecraft!

Roy,
 
The crackling happened here too when I first tried the noise gate but it stopped when I turned the threshold a bit higher. I assumed it was background noise breaching the threshold and a sign I hadn't got the setting right.
 
73 to all

Hello Roy!

Thank you for trying the new TX GATE feature.

Increase the threshold further.  Noise peaks are not uniform, and as you
increase the threshold you'll find that most of the noise stops but
occasional peaks still get through, resulting in the crackling you are
hearing.

Hear cracklies? Keep increasing the threshold!  After they stop,
increase it a bit more.

Another possible approach: Listening on the MON function, find the
*highest* level you can use (where your voice starts to get chopped) and
then set the threshold about midway between that point and the point
where the crackling noise stopped.

Roy Davis
In reply to this post by Roy Davis
I will be going to Bon Aire NA on the 21st with Kyle, WA4PGM, and others to participate in the CQWWSSB Contest.  I am taking My K3 #1366 along to be used as one of the stations.  If time permits before contest day, I hope to operate portable as PJ4\WK4Y.
 
Please work us in the contest.  The call for the contest will be PJ4E.
 
Thanks,
