Subject: Re: [Elecraft] K3 RIT & OFFSET ENGAGES A
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
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
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
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!
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
