K3 RIT & OFFSET ENGAGES AT RANDOM
Locked
 
|
I operated the 160 contest this weekend and I had several unexplainable
consistent events. My K3 randomly engages the RIT and adjusts a plus offset of about 25-75 Hz. This was noticed about 15 times or so during the contest and nothing was consistent about it. The plus offset did not appear to be exactly the same each time but I was more focused on turning the RIT off than noticing whether the offset was exactly the same. Has anyone experience this before?73¹s Greg N9GB ______________________________________________________________ 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] |

Are you using N1MM? I had the same thing happen for about a 10 minute period during the contest and clicked a few fields on N1MM related to RIT and it stopped. I meant to go back after the contest and learn about N1MM control of the RIT but my poor memory took over and I forgot about it! Thanks for reminding me. I've found that the worst thing about having a bad memory is that you forget that you have a bad memory and don't make notes! :-) 73, Bill WE5P > > On Dec 8, 2019 at 23:46, Greg Best <[hidden email]> wrote: > > > I operated the 160 contest this weekend and I had several unexplainable consistent events.

Hi Greg,
Yes, we experienced this during field day with KK5W. At first we thought there was a problem with one of the 9 K3 rigs, so we swapped it out. It happened again with the replacement rig. It was finally diagnosed to be RFI that was causing the problem. I am willing to bet you are experiencing the same problem. 73 de Jim - KE8G On Mon, Dec 9, 2019 at 6:43 AM Bill Weaver <[hidden email]> wrote: > > > Are you using N1MM?

I am glad to hear I am not going crazy. I was using N1MM when this happened. Twice during the contest N1MM froze and I had to shut it down and restart. I had loaded the latest version of the program a day before the contest. I will look to see if any settings need changing. Thanks for the note abt RFI as the amp sets next to the K3.

I speculate two issues, RFI usually due to CMC. For 160M one should
employ a good common mode choke on the feedline at the antenna feed point and another at the radio. See the research of K9YC on this topic. Secondly, a logging program issue. N1NM has been documented to occasionally have this issue. And it may be the first issue, CMC, causing an issue with the computer. FYI - I despise all logging programs as I find them more of a PITA than efficient use. 73 Bob, K4TAX On 12/8/2019 10:42 PM, Greg Best wrote: > I operated the 160 contest this weekend and I had several unexplainable > consistent events.

Never saw my post appear so am sending it again sans screenshot-Mike VE9AA

It's so if you are assisted and clicking on spots, all callers are not zero beat on the same frequency. I can tell you that being on the sharp end of a pileup more than once, it's horrible to get half dozen or whatever callers all at S1 and all zerobeat.
