rtty and MK2R+ K-3
Locked
 
|
Well audio can be found off the front headphone jack. Which is totally
wrong. Audio should be coming off the back line in and out. Something is not right. I am using a Microham set of cables for the K-3. Is there a "trick" to shut off headphone audio and take it off the back.

Audio is simultaneously available at front and rear headphone jacks, and at the LINE OUT jack. Nothing special need be done. CONFIG:LIN OUT and sets the LINE OUT level (nor 10, for example). You can safely insert headphones into the LINE OUT jack and verify there is audio coming out. It will probably be low in level, but present. To keep distortion to a minimum, use a level of 10 or less when feeding the sound card input. Remember LINE OUT on the K3 is receiver audio from the K3 to the PC and should go to the LINE IN connector on the PC soundcard. LINE IN is transmit audio to the K3 and should come from LINE OUT on the PC. If there is no audio at the K3's LINE OUT connector, even with the level set quite high (50, for example), email k3support. If there is audio, then the problem is not in the K3. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Interesting, that's the first time I've seen that advice. The range of
the Line Out control is 0 to 100, and according to the manual the default is 30. Is there a distortion problem at the default setting?

Bob,
That is highly dependent on the computer sound card. Lyle has recommended the setting of 10 to keep from overdriving the input of the sound card (overdriving the sound card will cause distortion). The 'problem' is *not* the K3 creating any distortion. Of course, if you are driving a device that needs more audio than the typical sound card, the range from 10 to 100 may be required - it all depends on the device. 73, Don W3FPR Bob Cunnings wrote: > Interesting, that's the first time I've seen that advice.

my "lin out" is set to nor 025 and the
MK2r "recording/ digital" controls on the bottom right front panel are set about 12 high.... and all my apps have great audio input.... bill At 08:32 PM 7/19/2008, Lyle Johnson wrote: >>Is there a "trick" to shut off headphone audio and take it off the back. > >Audio is simultaneously available at front and rear headphone jacks, >and at the LINE OUT jack.

Of course overdriving the sound card will cause distortion, and it's
also true that the amount of drive required depends, as you say, on the nature of the device being driven. That's why the statement caught my attention - taken at face value, it implied an absolute limit, without reference to the gain of the driven device. For example, in my case, it happens that LINE OUT is set to 25 to correctly drive the sound card in my PSK31 setup because as it happens, I'm using a cable with some attenuation built in. Anyway, anything that Lyle writes I read quite closely, so thought that I would ask!

Make sure Line Out in the K3 (CONFIG Menu) is set to NOR and with the level around 020. Also make sure the cable with the female pigtail is connected to the Line out jack of the K3 (some early K3 cable sets had the Line Out and Line In labels reversed). 73, ...

Is there a distortion problem at the default setting? Yes. I have measured significantly increased distortion on the line out with gain settings above about 10. I believe the line out xfmr is the culprit. Elecraft is aware of it. 73, Jim K9YC _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
