K3S MIC Problem
Locked
 
|
I'm guessing that I'm not the first to notice this on the K3S. I don't do
much SSB but was active in Sweepstakes this past weekend and noted that occasionally the audio would go dead. Looking around I found that the MIC gain had dropped from the usual (about 16) down to zero. I placed a toroid around the MIC cable and this seemed to prevent the problem most (but not all) of the time. The MIC cable (and the K3S) both sit next to an Alpha 87A amp. I don't recall reading about this. Is some protective function being activated? -- 73, William (Bill) Rogers / W3UL Annapolis, Maryland U.S.A. ______________________________________________________________ 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 Message delivered to [hidden email] |

Since I installed the KIO3B in my K3 I have had issues with RF getting into
the computer and into the radio via the ACC port (a toroid on the cable helped). I currently have the K3 on the bench, but parts are due tomorrow so I will be back on in a couple of days. I can't remember the last time I made a phone Q on it though so I will check that out. Will probably as did some ferrite on the USB cable too.

Hi friends and neighbours,
was there a contest logging software used? If so, I am thinking about a "mute of the MIC" My favourite mode is CW. But when ever I used SSB with N1MM+ I recognized such behaviour as described by Bill. 73 de Chris Am 23.11.2020 um 17:50 schrieb Bill Rogers W3UL: > I'm guessing that I'm not the first to notice this on the K3S.

I have not seen this occur, is there any chance that you were
adjusting the VOX or some other way of accidently bumping that control?

I have been using N1MM+ for years and this is the first time I recall
seeing this problem. I'll need to check the MIC muting possibility. I am a PTT footswitch person (no VOX used). Thanks for these tips. 73, Bill W3UL On Mon, Nov 23, 2020 at 1:44 PM Bill Rogers W3UL <[hidden email]> wrote: > I have been using N1MM+ for years and this is the first time I recall > seeing this problem. > > I am a PTT footswitch person (no VOX used).

The K3(s) as I understand it has protective circuitry that will reduce mic output if there are return power issues.
I once had an experience during Field Day where my K3 was suddenly not transmitting or doing so at a very low level. Mine was traced to a SO239 connector that had worked loose and was not making good connection. You can also try recalibrating TX to see if that helps. In my case the unit went back to the factory for diagnosis, inspection and repair. Elecraft's gentle ministrations restored it to full function and I have not had a problem since. -----Original Message----- From: [hidden email] <[hidden email]> On Behalf Of [hidden email] Sent: Monday, November 23, 2020 10:27 AM To: [hidden email] Subject: Re: [Elecraft] K3S MIC Problem I have not seen this occur, is there any chance that you were adjusting the VOX or some other way of accidently bumping that control?

MIC ISSUES...
"" The MIC cable (and the K3S) both sit next to an Alpha "" I think the proximity of the antenna/s is more relevant than the position of the amp box. I don't see a tower in the QRZ page view, so maybe there are some "close to the shack" antenna wires ????? bill On 11/23/2020 11:50 AM, Bill Rogers W3UL wrote: > I'm guessing that I'm not the first to notice this on the K3S.
