FM via K3
Locked
 
|
Gentlemen,
Is there any way to manipulate the transmitted audio when on FM using the K3??? Nothing in the manual suggests that it's even remotely possible, while of course when on SSB or AM it can be accomplished using either TX-EQ or ESSB! I ask this question because I work a club-rptr on 6mtrs w/FM and eventhough I'm FQ into the machine they mentioned to me that my FM transmitted audio sounded a tad (SHARP) lacking the fidelity of most mobile FM rigs available today!

Tx EQ is applied. You can adjust the deviation as well. 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Jim,
It certainly could be the bandpass response of the microphone element itself. What are you using for a microphone on the K-3? Check that out.

Hi Jim,
Like you I find the K3 lacking on both FM and AM. The audio sounds thin. The AM is lacking, in that with full mic gain and full compression I only get about 85 percent modulation. I would like to be able to control the audio as I can on SSB, which is excellent. Any chance of having another look at these modes in the near future, Wayne, Eric and Lyle? I've reverted back to the IC706 mk 2 for AM and FM and use the K3 on receive at the moment. 73 John Petters www.traditional-jazz.com Amateur Radio Station G3YPZ JIM DAVIS wrote: > Gentlemen, > > Is there any way to manipulate the transmitted audio when on FM using > the K3???

Hi John, Jim,
I have noticed this problem with AM for some time, and hope that a solution would soon be coming soon. 73 Bill Churchill AA1O On Jun 23, 2009, at 3:05 PM, john petters wrote: > Hi Jim, > Like you I find the K3 lacking on both FM and AM.

The Tx EQ is applied in AM and FM modes, so you should be able to tailor it pretty nicely. Some months ago (I don't know exactly when) the components in the Tx audio path, and Rx headphone path, were changed to improve low frequency response. > The AM is lacking, in that with full mic gain and full compression I > only get about 85 percent modulation. The most recent Beta release increases AM maximum modulation. 73, Lyle KK7P ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

That's great news Lyle. It looks better on my monitor scope. I will
try it live on our AM gray hair net tonight. Thanks for the great work. Bill AA1O K3 287 K2 1740 On Jun 23, 2009, at 3:16 PM, Lyle Johnson wrote: >> ...I find the K3 lacking on both FM and AM.

So does that mean that after some specific serial number there is
better LF response in both transmit and receive than earlier radios? Is this a change that can be worked into the mods list, or would it require replacement of the board(s)?

I'm having a hard time finding where these changes are. Were these changes
rolled into the current production? -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Lyle Johnson Sent: Tuesday, June 23, 2009 12:17 PM To: john petters Cc: 'Elecraft' Subject: Re: [Elecraft] FM via K3 > ...I find the K3 lacking on both FM and AM.
