Re: [Elecraft] Possible issue with K3 Line In port?
You might try a drop of Deoxit on the plug and then insert and remove several times Paula. I've had to do that with my K2 a couple of times. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 6/24/2019 3:05 PM, Paula Uscian wrote: Thanks to the many people who responded to my post, it is much appreciated.

FYI no difference with or without VOX. I have used VOX for RTTY AFSK in the past, but got disabused of that sin when I had some issues with WinWarbler that were resolved by running Commander.2. It is difficult for me to test a different cable as the TASCAM Line out consists of 2 RCA jacks. I happen to have a cable with 2 RCA plugs at one end and a 3.5mm plug at the other end, but I don't have another one to try (note to self -- get another cable just in case). However, I did run a totally different 3.5mm to 3.5mm cable from the Line Out (Green) port on the PC to the Line In port on the K3 and got the same failure (AFTER reconfiguring the software to look to the internal sound card for TX). Yes, it is possible I have 2 bad sound cards and 2 bad cables, but I'm playing the odds for next steps ;-).3. I have been using the meter selection that shows ALC during these tests.4. I do hear tones -- a steady tone when I click the Tune button and modulating tones when I click the TX button, in WSJT -- in my headset, so I think the TASCAM Line Out is working.I just see no bars on the ALC display. I also checked to make sure recent Windows 10 updates didn't alter my Privacy settings for the microphone; those permissions remain the same as when the system was working.

Re: [Elecraft] Possible issue with K3 Line In port?
Paula, Your problem may be as simple as bad cable connections between the K3 line in and your soundcard. I had the same problem that recurred several times and drove me nuts. I was getting audio out of the soundcard when going to transmit. (I also the problem with AFSK-A RTTY.) I finally found the problem by pressing on the cable at the line in port on the K3 while in TX mode and saw power out/ALC action return. Replacing the cable solved the problem. 73 de Ed Warning from God Discovered in Human DNA healthrevelations.net http://thirdpartyoffers.juno.com/TGL3141/5d1116ce27c1a16ce0819st03vuc __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] Possible issue with K3 Line In port?
Try changing the bar graph on the K3 from power to ALC by doing a hold of the DISP button then transmit. Check to see if the level is set properly, i.e. 4 bars with the fifth flickering. If not try setting the line-in gain to that level.

Re: [Elecraft] Possible issue with K3 Line In port?
Paula, Although you said 'it worked before', take a look at the ALC meter. With digital modes, you should have enough audio to drive it to 4 bars with the 5th bar flashing. See the article on my website www.w3fpr.com. Can you transmit in SSB mode? If so, the K3 audio is fine and you can focus on the Line In or the soundcard output for the problem source. 73, Don W3FPR On 6/24/2019 9:29 AM, Paula Uscian wrote: I suspect I may have an issue with the Line In port of my K3, as my ability to TX in any digital mode has gone away.

Re: [Elecraft] Possible issue with K3 Line In port?
Paula, Have you verified that you have audio out of the soundcard? Plug headphones or amplifier computer speakers into the soundcard line out jack and do a "transmit" from the software. Do you hear audio tones? If not, you have a soundcard problem. 73, Don W3FPR On 6/24/2019 9:29 AM, Paula Uscian wrote: I suspect I may have an issue with the Line In port of my K3, as my ability to TX in any digital mode has gone away.

[Elecraft] Possible issue with K3 Line In port?

When I try to TX on FT8 from within WSJT, the K3 red TX light comes on and over my headphones I can hear a steady tuning tone, but I have no power out, not one bar. 2. During TX I do hear “behind” the tones a brief low level buzzy/crackly sound that recurs every second or so. 3. I get the same results as above when trying to TX in WSJT, though I hear tones typical of a transmission vs. a steady tone. 4. I get the same results as above when I switch to RTTY and TX within WinWarbler; RYRYRY, but no power out. 5. The Tascam and WSJT work fine together to decode FT8 signals. T-shooting Steps to Date: 1.
